Few-Shot Segmentation Propagation with Guided Networks

2018 · arXiv (Cornell University)

Learning-based methods for visual segmentation have made progress on particular types of segmentation tasks, but are limited by the necessary supervision, the narrow definitions of fixed tasks, and the lack of control during inference for …

Split-Brain Autoencoders: Unsupervised Learning by Cross-Channel Prediction

2016 · arXiv (Cornell University)

We propose split-brain autoencoders, a straightforward modification of the traditional autoencoder architecture, for unsupervised representation learning. The method adds a split to the network, resulting in two disjoint sub-networks. Each sub-network is trained to perform …
