Incremental Training of Deep Convolutional Neural Networks

no code implementations27 Mar 2018 Roxana Istrate, Adelmo Cristiano Innocenza Malossi, Costas Bekas, Dimitrios Nikolopoulos

We propose an incremental training method that partitions the original network into sub-networks, which are then gradually incorporated in the running network during the training process.

BAGAN: Data Augmentation with Balancing GAN
