Biography

I received my B.Sc. degree from UESTC(University of Electronic Science and Technology of China) in June 2019. In the same year, I was admitted to study for a M.Sc. degree in Nanjing University without entrance examination.

I received my M.Sc. degree in School of Artificial Intelligence from Nanjing University in June 2022. In the same year, I was admitted to study for a Ph.D. degree in School of Artificial Intelligence from Nanjing University, which is also in the LAMDA Group led by Prof. Zhi-Hua Zhou., under the supervision of Prof. De-Chuan Zhan and Han-Jia Ye.

Research Interests

Lan mainly focuses on machine learning, especially:

Class-imbalanced Learning

• Class-imbalanced learning focuses on addressing the challenge of datasets with imbalanced class distributions, where one or more classes have significantly fewer instances compared to others. This problem is common in many real-world applications, such as medical diagnosis, fraud detection, and text classification.

Semi-Supervised Learning

• Semi-supervised learning is a broad category of machine learning that uses labeled data to ground predictions, and unlabeled data to learn the shape of the larger data distribution. Practitioners can achieve strong results with fractions of the labeled data, and as a result, can save valuable time and money.

Federated Learning

• Federated learning is a decentralized learning approach that enables training machine learning models on distributed data sources while keeping the data local and preserving privacy.
