Title: Representation Learning with Contrastive Predictive Coding. Authors: Aaron van den Oord, Yazhe Li, Oriol Vinyals Abstract: While supervised learning has enabled great progress in many applications, unsupervised learning has not seen such widespread adoption, and remains an important and challenging endeavor for artificial intelligence.

TopicRepresentation for representation learning [39, 48, 3, 40]. Contrastive predictive coding (CPC, also known as InfoNCE [49]), poses the MI estimation problem as an m-class classification problem. Here, the goal is to distinguish a positive pair (x;y) ˘p(x;y) from (m 1) negative pairs (x;y) ˘p(x)p(y).

2019-05-22 · Human observers can learn to recognize new categories of images from a handful of examples, yet doing so with artificial ones remains an open challenge. We hypothesize that data-efficient recognition is enabled by representations which make the variability in natural signals more predictable. We therefore revisit and improve Contrastive Predictive Coding, an unsupervised objective for learning

If 2018-08-15 · This post is based on two papers, my own note from February, Information-Theoretic Co-Training, and a paper from July, Representation Learning with Contrastive Predictive Coding by Aaron van den Oord, Yazhe Li and Oriol Vinyals. These two papers both focus on mutual information for predictive coding. A recent approach for representation learning that has demonstrated strong empirical performance in a variety of modalities is Contrastive Predictive Coding (CPC, [49]). CPC encourages representations that are stable over space by attempting to predict the representation of one part of an image from those of other parts of the image.

CPC encourages representations that are stable over space by attempting to predict the representation of one part of an image from those of other parts of the image. This paper introduces Relative Predictive Coding (RPC), a new contrastive representation learning objective that maintains a good balance among training stability, minibatch size sensitivity, and downstream task performance. The key to the success of RPC is two-fold.
