From tensor-network quantum states to tensorial recurrent neural networks

Giuseppe Carleo, Riccardo Rossi, Filippo Vicentini, Dian Wu

We show that any matrix product state (MPS) can be exactly represented by a recurrent neural network (RNN) with a linear memory update. We generalize this RNN architecture to two-dimensional lattices using a multilinear memory update. It supports perfect s ...
