Speech Title: Recent Progress on Weakly-Supervised Learning for Imperfect Data

Abstract:

Traditional supervised machine learning algorithms usually require sufficient, accurate, and definite training data during training. However, in many practical situations, due to a variety of objective limitations, the perfectness of training data is difficult to guarantee. Therefore, in this talk, I will mainly introduce the latest progress of our group in the field of weakly supervised learning. Focusing on common practical problems such as insufficient supervision, inaccurate supervision, and indefinite supervision, I will mainly introduce the corresponding machine learning algorithms including semi-supervised learning, PU learning, label noise learning, partial label learning, etc. The related theoretical results and empirical results will also be introduced.
