Prof. DR. KACHI YASUYUKI

University of Aizu, Japan

Abstract: At predominantly non-math-leaned institutions, the fact that math is a catalyst for inquisitive minds is often underappreciated. Regardless, many institutions reap benefits from retaining mathematicians within their faculty. Mathematicians in such an environment are in a bind, having to amass scholarly outputs that align with their ethos while keeping camaraderie with non-mathematicians intact. The flip side: while mathematician-faculty must value academic freedom, them pulling away from reality and not working to understand quantum computing, say, might mean an opportunity loss. In the era of renewed interest in technology, finding one’s own niche in an interdisciplinary environment goes a long way. I describe how my research evolved while coping with this trend at an engineering-centric university, prompted initially by the strategic rapprochement rather than “art-for-art's sake.”. I talk about a mathematical outlook that has grown on me, on (1) integer sequences (rhythm), (2) permutations (information security), and (3) random number generation (computational complexity). 

Towards an integral AI ethics: the emerging case of voice companions

In recent years, AI ethics has been a core part of the global conversation around the issues that matter. However, it is often seen as a tentative field, which is not only distinct from the purportedly more concrete field of AI regulation but also far less impactful for the real-world development of AI. This could not be farther from the truth. The relationship between regulation and ethics is underexplored yet an emerging field of study. However, it is clear that ethics cannot be segregated from regulation.

This can be witnessed quite clearly in a fast-emerging use case of AI-powered voice companions. They vividly illustrate how ethics and regulation must intersect through the ethical issue of the manner in which these companions shape and ‘nudge’ our behavior. Concrete regulation can only extend itself to cases of clear wrongs committed upon the user, such as deception, dark patterns, etc. However, the subtle, long-term behavior modification of users is a real ethical concern without any clear regulatory response. An ‘integral’ AI ethics must be developed that uses the subtle regulatory force of both social norms and technological design to counter the ethical concerns raised. 

The AI Revolution: The transformative role of Chatbots in Marketing and Customer Service

The rise of AI-powered chatbots is revolutionizing marketing and customer service, reshaping how businesses engage with consumers. These intelligent systems provide instant responses, streamline interactions, and enhance personalization, leading to improved customer satisfaction and brand loyalty. In marketing, AI-driven chatbots analyze user behavior, enabling hyper-targeted campaigns and predictive recommendations. Meanwhile, in customer service, they reduce wait times, handle multiple queries simultaneously, and offer 24/7 support. As AI evolves, integrating natural language processing and machine learning, chatbots are becoming more human-like, fostering deeper connections with users. However, ethical considerations, data privacy, and maintaining a balance between automation and human touch remain critical challenges. This keynote will explore AI’s transformative role and its future in digital engagement.
