| 研究実績の概要 |
In this year, our research has mainly addressed the problem of learning tensor network representation from data and deep learning modeling with tensor network fusion. Specifically, we have several contributions that are listed as follows.
1. We have developed reshuffled tensor decomposition and robust tensor Tubal nuclear norm based algorithm with theoretical support, which can provide exact recovery guarantee and improved tensor completion performance.
2. We developed outer product based tensor fusion framework, which can be employed in deep multimodal learning yielding ability to handing incomplete data. The experiments on multimodal sentiment analysis has validate its effectiveness and improved performance.

| 今後の研究の推進方策 |
In the next years, we plan to conduct research on tensor network representation and deep learning. The big model in deep learning is able to produce high performance but the storage and computation efficiency is low. To address this issue, we aim to develop effective model compression technology using tensor network representation, which can be applied to reduce significantly the number of parameters in modeling while keeping the performance comparable.
