Title: Model-Based Reasoning for Explainable AI as a Service

Abstract:
As AI systems are increasingly being adopted into application solutions, the challenge of providing explanations and supporting interaction with humans is becoming crucial. Partly this is to support integrated working styles, in which humans and intelligent systems cooperate in problem-solving, but also it is a necessary step in the process of building trust as humans migrate greater responsibility to such systems.
In this talk we discuss progress made in Explainable Planning, particularly in scenarios involving human-AI teaming, and we present recent advances in using model-based reasoning for designing Explainable AI as a Service.

Title: Some Shades of Grey! – Interpretability and explanatory capacity of deep neural networks

Abstract:
Based on the availability of data and corresponding computing capacity, more and more cognitive tasks can be transferred to computers, which independently learn to improve our understanding, increase our problem-solving capacity or simply help us to remember connections. Deep neural networks in particular clearly outperform traditional AI methods and thus find more and more areas of application where they are involved in decision-making or even make decisions independently. For many areas, such as autonomous driving or credit allocation, the use of such networks is extremely critical and risky due to their “black box” character, since it is difficult to interpret how or why the models come to certain results.  The paper discusses and presents various approaches that attempt to understand and explain decision-making in deep neural networks.

Title: Mapping the challenges and opportunities of CBR for eXplainable AI

Abstract:
The problem of explainability in Artificial Intelligence is not new but the rise of the autonomous intelligent systems has increased the necessity to understand how an intelligent system achieves its solution, makes a prediction or a recommendation or reasons to support a decision in order to increase transparency and user’s trust in these systems. The CBR research community has a great opportunity to provide general methods of self-understanding and introspection on other AI systems, not necessarily case-based. CBR provides a methodology to reuse experiences in interactive explanations and can exploit memory-based techniques to generate explanations to different AI techniques and domains of applications. This talk will review the state of art of XCBR, the synergies with the XAI community, and will give the opportunity to review the underlying issues like confidence, transparency, justification, interfaces, personalization and evaluation of explanations. It will include a review of the lessons learnt at the XCBR workshop and the challenges and promising research lines for CBR research related to the explanation of intelligent systems.
