Abstract:
In this talk, I will introduce our recent progresses in the machine learning models and algorithms based on tensor network (TN) from the following two aspects. First, TN can be regarded as a generalization of neural network (NN). A residual net formed by tensor blocks, named as residual matrix product state, was proposed for supervised learning. Meanwhile, we show that TN can be used as an efficient representation of high-order tensors that “exponentially” lowers the complexity. This conceived a powerful scheme for NN compression. Second, we show the interpretability of TN machine learning based on the quantum probabilistic interpretation. The theories of quantum entanglement and measurement were used to develop machine learning schemes for compressed sampling and feature selection.
