KEYNOTE: Explainable Artificial Intelligence, Explained
Peter Flach, Department of Computer Science, University of Bristol, UK
Abstract: Explainable Artificial Intelligence (XAI for short) aims at giving insight in the behaviour of AI models in general and machine learning models in particular. In this talk I will give an overview of this growing field, using some recent results from my group as examples. These include explainability for time series (LIMEsegment); actionable counterfactuals (FACE); explainability fact sheets; as well as the fat-forensics.org toolkit for evaluating Fairness, Accountability and Transparency of AI systems. Finally, I will discuss the importance of properly treating probabilities in feature attribution methods such as LIME and SHAP through log-linear models.

KEYNOTE: Machine Speech Chain: A Deep Learning Approach for Modeling Human Speech Perception and Production with Auditory Feedback Mechanism for Low-Resource Languages
Sakriani Sakti, Japan Advanced Institute of Science and Technology (JAIST), Japan
Abstract: The development of automatic speech recognition (ASR) and text-to-speech synthesis (TTS) has enabled computers to learn how to listen or speak, imitating the capability of human speech perception and production. However, computers still cannot hear their own voice, as the learning and inference to listen and speak are made separately and independently. Consequently, the separate training of ASR and TTS in a supervised fashion requires a large amount of paired speech-text data—furthermore, there is no ability to grasp the situation and overcome the problem during inference. On the other hand, humans learn how to talk by constantly repeating their articulations and listening to the sounds produced. By simultaneously listening and speaking, the speaker can monitor her volume, articulation, and the general comprehensibility of her speech. Therefore, a closed-loop speech chain mechanism with auditory feedback from the speaker’s mouth to her ear is crucial. In this talk, I will introduce a machine speech chain framework based on deep learning. First, I will describe the training mechanism that learns to listen or speak and to listen while speaking. The framework enables semi-supervised learning in which ASR and TTS can teach each other given unpaired data. Applications of multilingual and multimodal machine speech chains to support low-resource ASR and TTS will also be presented. After that, I will also describe the inference mechanism that enables TTS to dynamically adapt (“listen and speak louder”) in noisy conditions, given the auditory feedback from ASR.

INVITED TALK: Pedagogy-infused AI for Precision Education
Patcharin Panjaburee, Faculty of Education, Khon Kaen University, Thailand
Abstract: Artificial Intelligence (AI) has been recognized by scholars as one of the challenging research issues of education. Several researchers have indicated the challenges and importance of considering individual students when designing AI in education based on their learning status, preferences, or personal characteristics. This talk aims to review the current state of AI in education and proper pedagogies. To this end, various implementations of AI-based systems and harmonization of learning strategies are introduced in this talk, such as their implementations in mathematics, science, computer science, and information literacy courses for elementary school students to undergraduate students. Moreover, the experience and thinking of conducting these studies of pedagogy-infused AI for precision education and the promotion of the research results across Thai school and university settings are presented. With my experience in conducting research on pedagogy-infused AI for precision education, this talk is expected to ignite researchers and school or university teachers devoted to AI in education to reach interesting research issues and design effective AI-based learning approaches relevant to your context.
