Group sparse autoencoder

作者:

Highlights:

• Group Sparse AutoEncoder (GSAE) learns better discriminative features compared to an unsupervised autoencoder.

• Class label based ℓ2,1-regularization is incorporated to squared error reconstruction loss function using a majorization-minimization approach.

• The proposed GSAE is used to learn minutia representation from noisy latent fingerprint images.

• Results on standard image datasets, MNIST, CIFAR-10, and SVHN and latent fingerprint image datasets, NIST SD-27 and MOLF, show effectiveness of the proposed GSAE feature extraction approach.
