Objectives: The aim of this workshop is to bridge the gap between mathematical and biological researchers with an interest in the quantitative analysis of animal vocal sequences. Recent developments in the mathematical analysis of complex animal communication have generated opportunities to understand the functional aspects of animal vocalizations, their role in social organization, and ultimately to explore the origins and evolution of human language. Until now, however, the collaboration between mathematicians/computer scientists and biologists/zoologists in this field has been very limited. We aim to define the state of the art in this field, explore new horizons for collaboration, and provide new techniques through a synthesis of the mathematical and biological approaches to communication analysis. We will also use this unique gathering to define some of the key questions that need to be posed to address ultimate and proximate hypotheses about behavior, in the context of animal vocal communication systems.

Biologists can benefit from a broader set of tools and methodologies, whereas mathematicians can use the input of biologists to channel their research towards more biologically meaningful hypotheses. Current tools have brought us only so far in the analysis of vocal signals; new techniques such as analysis of non-linear phenomena, syntactic analysis, and network analysis, are necessary to move the field forward.

This workshop that will take a first step towards building a coherent community of researchers of animal vocal sequences, with a well-defined framework for collaborative research and consistent hypothesis-driven paradigms. It will bring together researchers specializing on key animal taxa (such as cetaceans, bats, song birds, etc), biologists investigating animal communication in general, cognitive psychologists and computational linguists, and mathematicians and computer scientists with specialist knowledge of key algorithms and analytical principles. The structure of the workshop will be highly interactive, with repeated sessions of one or two talks plus question and answer sessions, followed by break-out groups in which existing techniques can be scrutinized and new ideas floated. Four main subjects will be addressed:

  • state of the art in computational techniques;
  • finding common terminologies and comparative computational metrics;
  • defining the mathematical aspects of the important behavioral/evolutionary questions; and
  • specific computational challenges in the investigation of communication complexity.

We expect this workshop to provide biologists with a practical understanding of the methodologies available to them, to provide mathematicians with an understanding of the requirements of biologists in the development of new techniques and algorithms, and consequently to generate genuine collaborations between participants for continuing research. This synthesis is likely greater than the sum of its component parts – not only generating new ways of analyzing behavior, but possibly also new theory about behavior and behavioral interactions.

NIMBioS Investigative Workshops focus on broad topics or a set of related topics, summarizing/synthesizing the state of the art and identifying future directions. Organizers and key invited researchers make up half the 30-40 participants in a workshop, and the remaining 15-20 participants are filled through open application from the scientific community. Open applicants selected to attend are notified by NIMBioS within two weeks of the application deadline. Investigative Workshops have the potential for leading to one or more future Working Groups. Individuals with a strong interest in the topic, including post-docs and graduate students, are encouraged to apply. If needed, NIMBioS can provide support (travel, meals, lodging) for Workshop attendees, whether from a non-profit or for-profit organization.
