Understanding and Unifying Fourteen Attribution Methods with Taylor Interactions

no code implementations2 Mar 2023 Huiqi Deng, Na Zou, Mengnan Du, Weifu Chen, Guocan Feng, Ziwei Yang, Zheyang Li, Quanshi Zhang

Various attribution methods have been developed to explain deep neural networks (DNNs) by inferring the attribution/importance/contribution score of each input variable to the final output.

Cancer Subtyping by Improved Transcriptomic Features Using Vector Quantized Variational Autoencoder

no code implementations20 Jul 2022 Zheng Chen, Ziwei Yang, Lingwei Zhu, Guang Shi, Kun Yue, Takashi Matsubara, Shigehiko Kanaya, MD Altaf-Ul-Amin

As such, existing methods often impose unrealistic assumptions to extract useful features from the data while avoiding overfitting to spurious correlations.

Multi-Tier Platform for Cognizing Massive Electroencephalogram

no code implementations21 Apr 2022 Zheng Chen, Lingwei Zhu, Ziwei Yang, Renyuan Zhang

A spiking neural network (SNN) based tier is designed to distill the principle information in terms of spike-streams from the rare features, which maintains the temporal implication in the nature of EEGs.

Cancer Subtyping via Embedded Unsupervised Learning on Transcriptomics Data

no code implementations2 Apr 2022 Ziwei Yang, Lingwei Zhu, Zheng Chen, Ming Huang, Naoaki Ono, MD Altaf-Ul-Amin, Shigehiko Kanaya

In this paper, we propose to investigate automatic subtyping from an unsupervised learning perspective by directly constructing the underlying data distribution itself, hence sufficient data can be generated to alleviate the issue of overfitting.
