Abstract:
Over the past decade, machine learning has experienced remarkable advancements, positively impacting our daily lives. Alongside this progress, a distinctive requirement has emerged—stemming from privacy concerns, usability considerations, and the right to be forgotten—leading to the development of a new concept known as machine unlearning. In this talk, I will undertake a comprehensive exploration of machine unlearning. First, I will give the reasons behind the existence of this necessity. Second, I will talk about recent developments in this field. In the end, I will introduce some corresponding solutions for unlearning verification. This talk is mainly based on our recent papers:
