Research Summary

Qibin  Zhao(D.Eng.)

The modern machine learning technology achieves remarkable success, but it requires a large amount of high-quality data, large learning models as well as high computational power for training, which also leads to the lack of reliability and interpretability of well-trained models. Our team aims to develop the innovative models and algorithms for efficient, robust, and interpretable machine learning. In particular, we develop various tensor-based methods, leveraging tensor factorization and tensor networks, for efficient and robust representation learning as well as fast computation. We also conduct research on their theoretical analysis and applications in computer vision and neuroscience fields.
