CAA 2018 is coming up

The CAA (Computer Applications and Quantitative Methods) Conference has been for the last few years the main venue to modelling archaeologists. Next year does not disappoint either. In fact, CAA Tubingen features what may be the largest selection on simulation, complexity and ABM yet. The CfP closes on midnight,  29th of October (Sunday). Follow this link to submit an abstract.

To spare you some time here’s a quick selection + summary; You will find full session abstracts further below.

S19 Agents, networks and models – the overarching session for all things complexity, simulation, networks etc. If in doubt submit here.

S10 Expanding horizons – roundtable on computational models of large scale human/hominin movement, such as migrations, colonisations, etc.

S17 Early human land use – if your agents lived in Pleistocene Europe and had big noses chances are you will fit in this session.

S9 Show your code – want to demo your ABM? Have an ingenious snippet of code that streamlines the data analysis? Share your genius with us! Note that submission to this session does not count towards your ‘one podium presentation’.

S22 Social Theory after the spacial turn – how could we account for cognitive, social, and agency-like factors in our spatial models? Discuss! Or write an ABM to show how.

S16 Play, Process and Procedure – a session on archaeo-gaming but also on artificial worlds so it would be a shame if it didn’t feature a couple of ABMs.

S34 R as an archaeological tool – some of us write our simulations in R. Others use it to analyse their outcomes or wrangle the inputs. Either way this will be an interesting session for any archaeological modeller.

S19 Agents, networks and models: formal approaches to systems, relationships and change in archaeology

Even if much ink has already been spilled on the need to use formal, computational methods to represents theories, compare alternative hypotheses and develop more complex narratives, the idea is still far from being firmly established in archaeology. Complexity Science provides a useful framework for formalising social and socio-natural models and it is often under this umbrella term that formal models are presented in archaeology. It has a particular appeal for researchers concerned with humans, thanks to its bottom-up focus, which stresses the importance of individual actions and interactions as well as relations between system elements. Equally, archaeology is a discipline where long-term, large-scale shifts in social change, human evolution, or interactions with the environment are at the heart of our interests. Complexity Science offers an arsenal of methods that were developed specifically to tackle these kind of research questions. This session will provide a forum for archaeological case studies developed using Complexity Science toolkits as well as for more methodological papers. We invite submissions of models at any stage of development from the first formalisation of the conceptual model to presenting final results. Possible topics include but are not limited to applications or discussions of the following approaches: – Agent-based and equation-based modelling, – Network science, – System dynamics, – Game theory, – Long-term change in social systems, – Evolutionary systems, – Social simulation in geographical space, – Complex urban systems, space syntax, gravity models.

S10 Expanding horizons: confronting issues of scale, resolution, and representation in the study of human expansions

Panelists of this roundtable session will discuss theoretical and methodological issues associated with the study of prehistoric human expansions and computational methods used to represent them. From the earliest hominin expansions in Africa and Eurasia, to the settlement of Australia and the New World, to explorations of the world’s oceans: the historical record of humanity is structured by the movements of people over the earth. Human expansions have been facilitated by changing environmental conditions, technological innovations, and shifts in the social relationships between different human groups, all of which have consequences for patterning observed in the archaeological record. Many major human movements occurred at spatial and temporal scales that differ from that of both archaeological investigations and many conceptions of human culture, leaving room for a good deal of uncertainty and presenting challenges to the construction of prehistoric narratives. Computational modelling approaches like GIS, network analyses, and agent-based models, offer opportunities to place these narratives in a framework where different potential historical processes can be assessed and uncertainty can be quantified. How we represent our ideas about the past in computational form involves trade-offs between realism and generality, as well as negotiations between different areas of expertise. This roundtable will include panelists from a range of research specialisations in order to expose common issues in the field of modeling human expansions and generate ideas about how best to bring together these areas of expertise.

S17 Early human land use strategies during Middle and Late Pleistocene glacial and interglacial times in Europe

The transition from the Middle to the Late Pleistocene is characterised by the transition from a distinct glacial cold phase (MIS 6) to a distinct interglacial warm phase (MIS 5e; Eemian sensu stricto). While changes in climate, environment, vegetation and fauna are obvious, this session aims at identifying possible differences or continuities in Neanderthal hominin performances, resource space and range between MIS 6 and MIS 5e. Several research questions have been addressed by researchers of the project ‘The Role of Culture in Early Expansions of Humans (ROCEEH) and will be discussed during the session. What did climate, environment and vegetation look like during a distinct cold phase and a distinct warm phase? Did corridors and barriers change? Are resource space and dietary breadth greater during a warm phase? Did changes between glacial and interglacial times have any impact on Neanderthal lifestyles and behaviours? Is there a relationship between changing climatic and environmental conditions and the distribution of Neanderthal sites? Can we observe different site preferences in Middle and Late Pleistocene Neanderthals? Did human land use strategies change? Are tool diversity and mobility different between MIS 6 and MIS 5e? Does an interglacial – or rather a glacial with stronger challenges – trigger an expansion of cultural capacities and/or performances? Do glacial or interglacial phases lead to specific cultural adaptations? Several computer-assisted methods from different scientific fields that have been (or might be) applied to answer such questions shall be discussed. They include, among others, measurements of tool diversity, tool-flake-core ratios and artifact density; agent based modelling; modelling of climate and vegetation; GIS-based analyses and modelling of geographic parameters. Colleagues from all scientific fields are invited to contribute to the session.

S9 Show your code: task streamlining, reproducibility and replicability in archaeological computing

Once a fringe component of archaeology, digital data and methods are rapidly becoming commonplace, changing how we learn about and discuss the past (Bevan 2015). This presents many technical challenges, but also an opportunity to reshape archaeological science by automating many of the most tedious tasks while encouraging reproducibility and replicability of computer applications. This session will be part seminar and part live-coding demonstration to which we invite anyone with a working piece of code that automates or streamlines any task that may be undertaken by an archaeological practitioner. We ask participants to show their code, explaining what the code does and how it works to make it easier for others to use it (Eglen et al. 2017). In doing so the session will showcase the principles and benefits of open science (sensu Nosek et al. 2015). We invite demonstrations from all points in the production of knowledge, from building and using archaeological databases, to statistical analyses and modelling (simulation, GIS, etc), to dissemination and public engagement. We also welcome more traditional papers that can bear on the following issues: -Improving usability and discoverability of code; -Communicating coding results with non-experts; -Managing concerns regarding intellectual property and data ownership; -Maintaining code and data in the long term; -Using code examples for teaching archaeology. Whether you are producing grand-scale syntheses of big data or those bits of programming that make life just a little easier, we want to see your code! All programming languages welcome.

S22 Social theory after the spatial turn

The past has always offered new and interesting insights that could be simulated, modelled and evaluated with computational approaches. In recent years the applications of advanced geospatial statistics, as well as modelling have become a central methodological framework to analyse past human behaviour and societies in general. However, often archaeological applications falls short on the capacities of these methods or massively overestimate their potential. On the one hand it is clearly related to the pursuit of model and test assumptions. On the other hand causal expectations are strongly simplified and in general more basic statistics are used. Predominantly, this leads to rather simple, purely environmentally constraint versions of reality, neglecting the presence of more than a topographical landscape with certain resources. Other factors, such as a “landscape of ancestors”, differing perception of space, or unknown human factors are mostly ignored in the models. The social sciences have constantly stressed the complexity of human decision making and have successfully implemented complex statistical procedures, such as sophisticated self-learning algorithms in order to achieve a better representation of reality. However, societies modelled in archaeology are often devoid of this cognitive human factor, which cannot be represented in the predominantly deterministic, almost Darwinian models. Furthermore – if at all – theoretical frameworks which were long since updated in social sciences are used to retrospectively interpret the model’s outcome. In this session we wish to address and discuss this problem in current archaeological human behavioural research with an interdisciplinary approach of archaeology and sociology. We welcome theoretical as well as practical contributions on the inclusion of social theory in geospatial analyses and predictive modelling, new ideas for a theoretical framework, and how archaeology can deal with the fuzziness of human decision making, which is never purely environmentally driven.

S16 Play, Process, and Procedure: An Experiential Digital Archaeology

Videogames and virtual worlds have increasingly become areas in which archaeological research is situated. These emerging venues straddle the divide between analogue past and digital present, asking the archaeologist to consider where that divide exists in their own archaeology, or whether it exists at all. Through this session, researchers are asked to look towards these new settings for how process, procedure, and play are being incorporated into digital archaeology, and what challenges to traditional archaeological practice can be overcome by embracing spaces of play as research arenas. Designed as an experiential exercise, each participant is asked to condense their presentation into 15 minutes, and one digital slide. Immediately following the presentation of papers, a working session to incorporate the themes of the session into prototype archaeological experiences of play will see participants creating together, and making the results of their collaboration available for further comment and discussion during the conference.

S34 R as an archaeological tool: current state and directions

In recent years, R has silently become the workhorse for many quantitative archaeologists. It’s open source, platform-independent and can be linked very well with other programming languages. As an interpreted language with simple and flexible syntax it is easy to learn but hard to master. Due to its huge community, spanning from hobbyist to commercial data scientists and researchers from scientific fields like statistics, ecology or linguistics, the catalogue for freely available packages is enormous and continuously growing. The foundation of the R-Consortium, a group of corporations highly invested in R, including Microsoft, IBM and Google, pushed the language and its abilities further ahead. Nevertheless, there are still many colleagues who have not yet realised the potential of the language and how easy it is today to conduct high quality research with the available tools. This is reflected by the fact that the workflow of many students of archaeology is at best still limited to Excel or SPSS. The solutions for archaeological problems in R are already manifold — although maybe developed for a different purpose. For example spatial analysis, multivariate statistics and scientific visualisation are well reflected within popular R packages, which makes it a very useful tool for archaeological research, teaching and publication. R also provides an advanced environment to produce truly reproducible research, which will be of growing importance in the future of scientific dialogue. Within this session we would like to explore the state of the art and the potential application of R in archaeology. We invite presentations for this session that explore questions like (but not limited to): * What are the specific benefits of this statistical framework in the eyes of its users? * What are the possibilities? What are the limits? * What future directions might the usage of R in archaeology have? * Which archaeological package has been developed, and which package still has to be developed to improve the usability of the software for archaeologists? * What has to be considered to optimise the workflow with R? We especially would like to attract colleagues who might present archaeological R packages that are ready or in the making and demonstrate their relevance for archaeological analysis. Also we would like to encourage potential presenters to demonstrate their research approaches via live coding, for which we would support them in ensuring that their presentations will work offline and on foreign hardware. If desired, we would like to publish the session and the code in an open online book embedded with runnable code. We hope to foster a productive and inclusive exchange between both young and experienced users from all backgrounds.

Digital Archaeology Sessions at the Brazilian Archaeological Society Congress

Our colleagues in Brazil are planning two sessions on digital archaeology at the Brazilian Archaeological Society Congress (Teresina, 10-15 September). So if you working in or with South American archaeology, this may be of interest. Note the close deadline: 7th of July. For more information see below or get in touch with Grégoire van Havre (gvanhavre at gmail dot com).

Call for Papers - Brazilian Archaeology Society Congress

The Brazilian Archaeology Society will meet in Teresina (Brazil) in September 10-15, and there are two session proposals (yes, two!) dedicated to computers and digital archaeology. Check out the official website for more details (in Portuguese): http://www.sab2017.com.br. The call for papers was extended to July, 7.

Both sessions are calls to gather computer archaeologists from around the country, as well as people from abroad working in Southern American contexts, and discuss experiences and problems.

1. Computer resources for archaeology: from excavation to data analysis
2. IPads in the Trenches: Digital Archaeology in Brazil - where are we?

This will be the first time digital archaeology and computer matters will be directly addressed in a national congress in Brazil.

Come to Cancun to talk about the Evolution of Cultural Complexity

The annual Conference on Complex Systems is one of the scientific gatherings where researchers present, discuss and debunk all things complex. This year it would be a double shame to miss it since it takes place in Cancun, Mexico between 17-22 September. If anyone needs any more encouragement, we are organising an exciting session focused on the evolution of broadly defined cultural complexity. Please send your abstracts by the 26th of May here. Any questions? Drop us an email: ccs17-at-bsc-dot-es
Details below and on the website: https://ccs17.bsc.es/

Scientific Background

Human sociocultural evolution has been documented throughout the history of humans and earlier hominins. This evolution manifests itself through development from tools as simple as a rock used to break nuts, to something as complex as a spaceship able to land man on other planets. Equally, we have witnessed evolution of human population towards complex multilevel social organisation.

Although cases of decrease and loss of this type of complexity have been reported, in global terms it tends to increase with time. Despite its significance, the conditions and the factors driving this increase are still poorly understood and subject to debate. Different hypothesis trying to explain the rise of sociocultural complexity in human societies have been proposed (demographic factor, cognitive component, historical contingency…) but so far no consensus has been reached.

Here we raise a number of questions:

  1. Can we better define sociocultural complexity and confirm its general tendency to increase over the course of human history?
  2. What are the main factors enablingan increase of cultural complexity?
  3. Are there reliable way to measure the complexity in material culture and social organisationconstructs, that is?
  4. How can we quantify and compare the impact of different factors?
  5. What causes a loss of cultural complexity in a society? And how often these losses occurred in the past?

Goals of the session

In this satellite meeting we want to bring together a community of researchers coming from different scientific domains and interested in different aspect of the evolution of social and cultural complexity. From archaeologists, to linguists, social scientists, historians and artificial intelligence specialists – the topic of sociocultural complexity transgresses traditional discipline boundaries. We want to establish and promote a constructive dialogue incorporating different perspectives: theoretical as well as empirical approaches, research based on historical and archaeological sources, as well as actual evidences and contemporary theories. We are particularly interested in formal approaches which enable more constructive theory building and hypothesis testing. However, even establishing common vocabulary of terms and concepts and discussing the main methodological challenges in studying sociocultural complexity is an important step towards a more cohesive framework for the understanding of cultural evolution in general and for individual research case studies in particular. Our approach is informed by the convergence between simulation and formal methods in archaeological studies and recent developments in complex systems science and complex network analysis.

The session will focus but is not limited to:

  • Social dynamics of innovation.
  • Cumulative Culture and social learning.
  • Evolution of Technology and technological changes
  • Cognitive Process,Creativity, cooperation and innovation
  • Population Dynamics and Demographic Studies
  • Computer tools to understand the cultural evolutionary change

CAA 2016 Session Videos

Continuing on the video theme: awhile back we encouraged folks to attend this year’s Computer Applications in Archaeology conference in Oslo. It was a blast to attend, and Oslo is a really cool city to spend a week in. I even briefly considered staying on to start a career doing car advertisements..

However, if you weren’t able to make it up to Oslo, Doug Rocks-Macqueen, author of the excellent blog Doug’s Archaeology, has you covered: his session recordings have been making their way out on to the interwebs via his YouTube channel, Recording Archaeology. Now you can relive all of the action of CAA Oslo right in your own home!

Here’s a few of the sessions, helpfully organized as playlists of individual talks:

Linked pasts: Connecting islands of content

Methodology of archaeological simulation. Meeting of the Special Interest Group in Complex Systems Simulation

The road not taken: Modelling approaches to transport on local and regional scales

Can you model that? Applications of complex systems simulation to explore the past

Networking the past: Towards best practice in archaeological network science

CfP: Computer Applications in Archaeology, March 14 – 17, Atlanta, GA USA

The folks at CAA have recently announced a call for papers for the 2017 conference, to be held at Georgia State University in Atlanta. From the conference website:

The 45th CAA conference will bring together scholars from across the globe to share their cutting edge research from a diverse range of fields in a focused, but informal, setting.  One thing that the CAA prides itself on is a strong sense of community, and we hope to continue to grow that community by welcoming new participants this year.  This is only the 3rd time the conference has been held in the United States, and we are excited to have old and new members join us in Atlanta this coming spring.

There are a TON of sessions to choose from this year, showcasing the diversity of computational approaches in archaeology as well as interest in theory and ways of knowing. The full list of sessions is here.

The authors of this blog will be co-chairing a few different sessions at the conference, including:

 

Data, Theory, Methods, and Models. Approaching Anthropology and Archaeology through Computational Modeling

Quantitative model-based approaches to archaeology have been rapidly gaining popularity. Their utility in providing an experimental test-bed for examining how individual actions and decisions could influence the emergence of complex social and socio-environmental systems has fueled a spectacular increase in adoption of computational modeling techniques to traditional archaeological studies. However, computational models are restricted by the limitations of the technique used, and are not a “silver bullet” solution for understanding the archaeological and anthropological record. Rather, simulation and other types of formal modeling methods provide a way to interdigitate between archaeology/anthropology and computational approaches and between the data and theory, with each providing a feedback to the other. In this session we seek well-developed models that use data and theory from the anthropological and archaeological records to demonstrate the utility of computational modeling for understanding various aspects of human behavior. Equally, we invite case studies showcasing innovative new approaches to archaeological models and new techniques expanding the use of computational modeling techniques.

Everything wrong with…

This is a different kind of session. Instead of the normal celebration of our success this session will be looking at our challenges. But, not degrading into self-pity and negativity, as it will be about critical reflection and possible solutions. The goal of this session is to raise the issues we should be tackling. To break the mold of the typical conference session, in which we review what we have solved, and instead explore what needs to be solved. Each participant will give a short (max 10 minutes but preference will be for 5 mins.) presentation in which they take one topic and critically analysis the problems surrounding it, both new and old. Ideally, at the end each participant would have laid out a map of the challenges facing their topic. The floor will then be opened up to the audience to add more issues, refute the problems raised, or propose solutions. This is open to any topic- GIS, 3D modelling, public engagement, databases, linked data, simulations, networks, etc. It can be about a very narrow topic or broad ranging e.g. everything that is wrong with C14 dating, everything wrong with least cost path analysis in ArcGIS, everything wrong with post-prossussalism, etc. However, this is an evaluation of our methods and theories and not meant to be as high level as past CAA sessions that have looked at grand challenges e.g. the beginning of agriculture. Anyone interested in presenting are asked to submit a topic (1-2 sentences) and your estimated time to summarize it (5 or 10 minutes). Full abstracts are not necessary.

The ups and downs of archaeological simulation

The continuing rise of computational modelling applications, in particular simulation approaches, resembles the ‘hype’ cycles our discipline experienced in the past. The introduction of statistics, data management or GIS all started with inflated expectations and an explosion in applications, followed by a ‘correction’ phase seeing the early optimism dwindling and a heavy critique towards exaggerated claims and examples of misapplication. The next phase, ‘maturity’, is reached when the use of a particular technique is not questioned any more (although particular applications of it may still be) as it becomes part of the standard research toolkit. The verdict is still out whether the use of simulation techniques in archaeology is reaching the peak of the ‘optimism’ phase or is perhaps still in the midst of the ‘correction’ phase. However, lessons learned from other, now commonly used, computational methods or coming from other disciplines could accelerate the process of establishing simulation in the mainstream of archaeological practice. The Special Interest Group in Complex System Simulation would like to open the discussion to a wide audience of archaeologists and therefore invites all CAA2017 participants to take an active part in the roundtable. During the meeting we will consider the current place of simulation in archaeological practice, the main challenges facing modellers and the road map for the future.

The conference promoters are also looking for folks interested in putting together workshops for the day before the session. The deadline for abstract submissions is midnight on Friday, October 28th. For more information, visit the CAA conference website.

CFP: SwarmFest 2016, Burlington, VT Jul 31 – Aug 3

Possibly the longest running meeting on agent-based modeling, SwarmFest, is being held this July at the University of Vermont campus in Burlington. Now in its 20th(!) year, SwarmFest brings together people from a range of backgrounds in ABM and simulation. From the website:

SwarmFest is the annual meeting of the Swarm Development Group (SDG), and one of the oldest communities involved in the development and propagation of agent-based modeling.  SwarmFest has traditionally involved a mix of both tool-users and tool-developers, drawn from many domains of expertise.  These have included, in the past, computer scientists, software engineers, biomedical researchers, ecologists, economists, political scientists, social scientists, resource management specialists and evolutionary biologists.  SwarmFest represents a low-key environment for researchers to explore new ideas and approaches, and benefit from a multi-disciplinary environment.  

Given the concentration of computational and complexity labs at UVM, this promises to be a very exciting meeting. And summertime is a fantastic time to be on Lake Champlain, or really any lake in New England, so I wholeheartedly recommend the trek to Burlington.

Call of abstracts closes June 15th, so get in quickly. For more info, see the website.

CSS2016 Amsterdam

If the most important annual conference in complex systems simulation is anything to go by then researchers in humanities are slowly infiltrating the ranks of complexity scientists.

This year the CSS (Complex Systems Society) conference is taking place in Amsterdam between 19-22 September. It is structured a bit differently than traditional conferences, that is, it consists of two main parts:

  • Core sessions such as “Foundations of Complex Systems” or “Socio-ecological Systems”, which are held every year, and
  • Satellite sessions, usually focusing on smaller topics or subdisciplines, which are proposed independently and, therefore, change from one year to another.

Archaeology (and humanities in general) has been on and off the agenda since 2013 but usually this meant one dedicated session and perhaps a paper or two in the core sessions classified as social systems simulations. However, this year there seems to be a bit of an explosion (let’s call it ‘exponential growth’!) in the number of sessions led by folk who have interest in the past. These three are particularly relevant:

10. Complexity and the Human Past: Unleashing the Potential of Archaeology and Related Disciplines
Organizer: Dr. Sergi Lozano

26. Complexity History. Complexity for History and History for Complexity 
Organizer: Assoc Prof. Andrea Nanetti

27. The Anthropogenic Earth System: Modeling Social Systems, Landscapes, and Urban Dynamics as a Coupled Human+Climate System up to Planetary Scale
Organizer: Dr. John T. Murphy

In addition, there are a number of satellite sessions that, although not dealing specifically with past systems, may be of interest for anyone who deals with evolution, urban development, economic systems or networks and game theory.  Finally, the most excellent student conference on complex systems (SCCS) will run just prior to the main event, between 16-18 September.

To submit an abstract, get in touch with the session organiser (you can find their emails here). The official deadline is 10th July, but the organisers may have imposed a different schedule so get in your abstract soon. And see you all in Amsterdam!

How useful is my model? Barcelona, 24-26 May

Our colleagues from Barcelona are organising a two-day workshop on the challenges of relating formal models (not only ABMs but other types of simulation and computational models as well) to the archaeological data. See below for an extended summary. The deadline for abstract submission has been extended to 25th April. For more information, check out their website.

Aim

The last decade saw a rapid growth of quantitative and computational methods apt to analyse long-term cultural and biological processes. In particular, the wide diffusion of agent-based simulation platforms and the enhanced accessibility of computer-intensive statistical analyses are offering the possibility to replace explanations based on natural language with formal models.

While these advances are providing powerful tools that are enabling us to tackle old and new research questions, their use is rarely coupled with appropriate epistemological discussions on how to ultimately relate the model to the data. Problems such as the choice of an appropriate statistic describing the empirical record, the balance between parsimony, complexity, and goodness-of-fit, the integration of taphonomic and sampling biases, or the inferential framework for selecting or rejecting alternative hypotheses rarely occupy the spotlight. In the case of simulation models, discussions are often limited to the model-building stage, and comparisons between prediction and observation are too often qualitative and not supported by sufficient statistical rigour. Yet this is the fundamental step that enables us to evaluate our models. In historical sciences, where the challenges imposed by the nature and the quality of our samples is at its greatest, this issue deserves more discussions and solutions. We believe that this is a critical issue that transcends the specific used in each discipline and cannot be dismissed as a challenge for statisticians.

We invite experts at different stage of this endeavour, sharing the same challenge of evaluating archaeological, historical, and anthropological model to the empirical evidence. We welcome the widest range of expertise (e.g. agent-based simulation, phylogenetics, network analysis, Bayesian inference, etc.) in order to promote the cross-fertilisation of techniques, as well as to engage into deeper theoretical and methodological discussions that transcends the specific of a given geographical and historical context. Participants will present examples showcasing problems (and solutions) on a variety of topics, including: uncertainty in the observed data, parameter search and estimation, model reusability and reproducibility, and more broadly applications of hypothesis testing and model-comparison frameworks in archaeology, anthropology, and history.
