| Outline of Final Research Achievements |
Tensor decomposition and tensor networks (TNs) have recently gained increasing attentions in machine learning, data mining and computer vision fields due to its effectiveness in efficient computation and model compression in deep learning. However, there are many open problems that are still unexplored, which limits its impact in machine learning. In this project, we studied the fundamental model and theory of tensor networks and applied it for data representation and model representation. We have introduced a novel tensor decomposition model together with fast and scalable algorithms which can be applied to large-scale data completion and image denoising. In addition, we also developed deep multi-task, multi-model learning and multiple GANs methods based on tensor network representations, which shows powerful expressive ability and economic model complexity.
