International Workshop: AI-Biz2021

November 15, 2021:
Online (because of COVID-19 pandemic):

Aims and Scope

The objective of this workshop is to foster the concepts and techniques of“Business Intelligence (BI).” in Artificial Intelligence. BI should include such cutting-edge techniques as data science, agent-based modelling, complex adaptive systems, and IoT. The application areas include but not limited to business management, finance engineering, service sciences, manufacturing engineering, and so on.

The basic idea of BI would enhance the capabilities of conventional techniques in business domain, however, so far, we have not discussed BI concepts deeply in artificial intelligence literature. We would like to focus on BI topics to the issues of firms and organizations for getting more benefits on interactions with human- and computer- mixed systems.

The main purpose of this workshop is to provide a forum to discuss important research questions and practical challenges in Business Intelligence, Business Informatics, Data Analysis and Agent-based Modelling to exchange latest results, to join efforts in solving the common challenges. It is also to establish an effective communication between researchers and developers involved in the both areas. The workshop will provide opportunities for the participants to exchange new ideas and experiences to establish research or business network and to find global partners for future collaboration.

Prof. Tzai-Hung Wen

Building an Agent-based Network Model for Simulating Epidemic Outbreaks and Epidemic-induced Medical Demand


Due to the complex interactions between human behaviors and the environment, it is essential to quantify the association between epidemic progression and human spatial behaviors. We proposed a methodological framework for generating geospatial agent-based networks and established a spatially explicit model for simulating epidemic outbreaks and epidemic-induced medical demand. The model combined dynamic epidemic process and resource accessibility to assess the availability of medical resources. We used the model to characterize the spatiotemporally dynamic patterns of the COVID-19 transmission under different ration levels of medical resources. It demonstrates that the medical resource demand and ration level in each area varies over space and time. The methodological framework captures the spatial-temporal dynamics of epidemic-induced demand and establishes the integrated accessibility modeling to deal with time-varying demand. It clarifies the effects of medical resource accessibility on disease transmission dynamics.

Empirical inference for agent-based models, where are we going next?


We want our agent-based models to answer empirical questions and provide actionable insights. This can only be done if our agent-based models can be informed by the large amount of data the world collects. Because of their nature, it has often been difficult to "fit" agent-based models and their parameters to data. Fortunately, in the past ten years a large number of methods and techniques have been developed to parameterise simulation models; these have often proved successful but their limitations have also become apparent. In this talk, we will review recent developments, test their limits in agent-based models and look at possible future avenues for research.
