Behavior Informatics, and Behavioral AI, [1,2] refer to a research area that aims to develop methodologies, techniques and practical tools for representing, modeling, analyzing, understanding, managing and utilizing observable, symbolic, mapped and non-occurring behaviors, behavioral interactions, behavior networks, behavior patterns, behavior impact, the formation of behavior-oriented groups, collective intelligence, consequences, the emergence of behavioral intelligence, and their causes and evolution.
In essence, behavioral AI, analytics, computing and informatics seek to deliver quantitative and computational technologies and tools to deeply understand behaviors, social behavior networks, their evolution, effect and impact. In this sense, we also call it behavioral computing. As a research issue, BI consists of many research directions that are worthy of systematic research and conducting case studies from aspects such as behavioral data construction, behavior modeling and representation, behavior impact modeling, behavior pattern analysis, behavior network analysis, non-occurring behavior analysis , and behavior intervention and management. Additionally, behavior measurement and evaluation, behavior presentation, and behavior use are very important topics.
Why Behavioral AI, Computing and Informatics
Behavior forms a critical ingredient and engine of human beings, artificial systems, business, society, environment, and economy. Behavior is ubiquitous, and behavior intelligence drives the development, consequence, and evolution of our human beings, artificial systems, business, society, environment, and economy.
Complex behaviors are widely seen in artificial and natural intelligent systems, on the internet, physical and virtual systems, social and online networks, multi-agent systems, and brain systems. The in-depth understanding of complex behaviors has been increasingly recognized as a crucial means for disclosing interior driving forces, causes and impact on businesses in handling many challenging issues.
However, traditional behavior modeling mainly relies on qualitative methods from behavioral science and social science perspectives. The so-called behavior analysis in behavior science and data analytics and learning often focuses on human demographic and business usage data, in which behavior-oriented elements are hidden in routinely collected transactional data. As a result, it is ineffective or even impossible to deeply scrutinize native behavior intention, lifecycle, dynamics and impact on complex problems and business issues.
Behavioral AI, analytics, computing and informatics aim for an in-depth analysis of behaviors and their interior driving forces, causes and impact. Behavior informatics consists of theoretical and applied studies on high impact behavior sequence analysis, impact-oriented combined behavior analysis, high utility behavior analysis, nonoccurring behavior analysis, coupled, group and collective behavior analysis , statistical modeling of coupled behaviors, probabilistic modeling of sparse rating behaviors, understanding behavior choice and attraction, behavior analysis with recurrent networks, behavior analysis in visual data, behavior learning from demonstrations.
The research topics include but are not limited to the following areas:
- What is Behavior: abstract behavior model to capture both intrinsic and contextual properties of behaviors from both subjective and objective perspectives;
- High Impact and High Utility Behavior Analysis: algorithms and case studies to identify behaviors associated with high impact and utility;
- Nonoccurring Behavior Analysis: algorithms and case studies about analyzing and mining negative behavior sequences in an efficient way;
- Coupled, Group and Collective Behavior Analysis: algorithms and case studies for identifying and analyzing group/community behaviors and anomalies;
- Statistical Modeling of Coupled Behaviors: statistical models to induce explicit and implicit couplings between attributes into statistical models for modeling behaviors;
- Understanding Behavior Intent: choice modeling, attraction learning and deep models to learn user choice and attraction and sequential interactions;
- Behavior Analysis with Recurrent Networks: deep recurrent networks to address behavior sequence analysis problems using several representative cases;
- Behavior Analysis in Visual Data: traditional approaches and recently emerged deep learning-based approaches for learning visual behaviors;
- Behavior Learning from Demonstrations: advanced imitation learning approaches to imitate human behaviors in a set of demonstrations data;
- Challenges and Prospects: open issues and potential of complex behavior modeling, analysis and mining in terms of both qualitative and quantitative aspects.
