Knockoff-Inspired Feature Selection via Generative Models

no code implementations25 Sep 2019 Marco F. Duarte, Siwei Feng

While variable selection in statistics aims to distinguish between true and false predictors, feature selection in machine learning aims to reduce the dimensionality of the data while preserving the performance of the learning method.

Semi-Supervised Endmember Identification In Nonlinear Spectral Mixtures Via Semantic Representation

no code implementations3 Jan 2017 Yuki Itoh, Siwei Feng, Marco F. Duarte, Mario Parente

This paper proposes a new hyperspectral unmixing method for nonlinearly mixed hyperspectral data using a semantic representation in a semi-supervised fashion, assuming the availability of a spectral reference library.
