Boosted Sparse and Low-Rank Tensor Regression

Lifang He, Kun Chen, Wanwan Xu, Jiayu Zhou, Fei Wang

Neural Information Processing Systems

We propose a sparse and low-rank tensor regression model to relate a univariate outcome to a feature tensor, in which each unit-rank tensor from the CP decomposition of the coefficient tensor is assumed to be sparse.

Backpropagation with Callbacks: Foundations for Efficient and Expressive Differentiable Programming

Fei Wang, James Decker, Xilun Wu, Gregory Essertel, Tiark Rompf

Neural Information Processing Systems

In this paper we propose an implementation of backpropagation using functions with callbacks, where the forward pass is executed as a sequence of function calls, and the backward pass as a corresponding sequence of function returns. A key realization is that this technique of chaining callbacks is well known in the programming languages community as continuation-passing style (CPS) .
