CAAI Cloud Classroom Lesson 9: Zhang Benyu, chief scientist of Ant Financial Services Group sharing Laboratory, explained that "connecting big data's isolated island"


The prevention and control of the epidemic will not be relaxed, and learning will not be interrupted. In this special period, Chinese Association for Artificial Intelligence (CAAI) explored the innovation mode of academic exchange, built a bridge connecting the knowledge of intelligent science and technology with the screen around AI academic and technology, and set up a series of activities such as CAAI Cloud Classroom for CAAI members and AI practitioners. With the support of Green Platform of China Association of Science and Technology (CAST), we will provide free and high-quality knowledge services through cutting-edge and high-quality courses. Let's start cloud interaction, face to face with the lecturer!

Brilliant Course

The theme of this course of Mr. Zhang Benyu's live course is "connecting big data's isolated Island, making multi-party data available and unavailable."

Abstract: so far, machine learning is basically based on a strong assumption that the distribution of training data is the same as that of test data. This assumption is not true in many practical applications. For example, in Internet data mining, the distribution of web pages may be out of date.

This defect will lead to a great decline in the function of the classifier, and it is not realistic to retrieve and label new data in many applications. This is a problem called transfer learning. The crux of the question is whether we can learn to follow suit. In this lecture, I will review and summarize the context of transfer learning, and systematically describe our recent research progress in this area.
