Fast Block Linear System Solver Using Q-Learning Schduling for Unified Dynamic Power System Simulations

no code implementations12 Oct 2021 Yingshi Chen, Xinli Song, HanYang Dai, Tao Liu, Wuzhi Zhong, Guoyang Wu

The simulation on some large power systems shows that our solver is 2-6 times faster than KLU, which is the state-of-the-art sparse solver for circuit simulation problems.

An iterative K-FAC algorithm for Deep Learning

no code implementations1 Jan 2021 Yingshi Chen

This CG-FAC method is matrix-free, that is, no need to generate the FIM matrix, also no need to generate the Kronecker factors A and G. We prove that the time and memory complexity of iterative CG-FAC is much less than that of standard K-FAC algorithm.

A short note on the decision tree based neural turing machine

no code implementations27 Oct 2020 Yingshi Chen

Differentiable forest is actually decision tree based neural turing machine.

Attention augmented differentiable forest for tabular data

1 code implementation2 Oct 2020 Yingshi Chen

So TAB block would learn the importance of each tree and adjust its weight to improve accuracy.

Learning Unsplit-field-based PML for the FDTD Method by Deep Differentiable Forest

no code implementations7 Apr 2020 Yingshi Chen, Naixing Feng

The deep differentiable forest (DDF) model is introduced to replace the conventional perfectly matched layer (PML) ABC during the computation process of FDTD.

Deep differentiable forest with sparse attention for the tabular data

1 code implementation29 Feb 2020 Yingshi Chen

We present a general architecture of deep differentiable forest and its sparse attention mechanism.

LiteMORT: A memory efficient gradient boosting tree system on adaptive compact distributions

1 code implementation26 Jan 2020 Yingshi Chen

In many cases, it only need the data source itself and no extra memory.

An optical diffractive deep neural network with multiple frequency-channels

1 code implementation23 Dec 2019 Yingshi Chen, Jinfeng Zhu

Diffractive deep neural network (DNNet) is a novel machine learning framework on the modulation of optical transmission.
