摘 要：Interpretability and generalizability of deep neural network learning methods are the main concerns and limitations when solving inverse problems in real-world applications. Despite of numerous empirical successes in recent years, deep-learning based methods are generally difficult to interpret and prune to overfitting, lack convergence guarantee, and can be extremely data demanding. In this short course, I would like to share our recent work to address those challenges. I will present: (1) our exact and inexact learned decent algorithms (LDAs), which induce efficient network architectures for solving a class of inverse problems; (2) our generalizable MRI reconstruction method with diverse dataset to tackle the task specific and extremely data demanding problems in deep learning based methods; (3) how to use multi-source/multi-domain complementary information to improve the performance of deep neural networks, respectively, in three talks.
