A novel dimension reduction and dictionary learning framework for high-dimensional data classification

作者:

Highlights:

• A novel dimension reduction and dictionary learning framework is proposed.

• At dimension reduction stage, it learns a nonlinear mapping via an autoencoder.

• At dictionary learning stage, it preserves local structure and enhances class discrimination.

• The nonlinear mapping and dictionary are optimized jointly.

• It preserves nonlinear structure within data and results in enhanced classification performance.
