Audio. For this first batch of experiments, the authors used 100 hours of the LibriSpeech 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. In this work, we propose a universal unsupervised learning approach to extract useful representations from high-dimensional data, which we call Contrastive Predictive Coding. The Representation Learning with Contrastive Predictive Coding Aaron van den Oord, Yazhe Li, Oriol Vinyals DeepMind Presented by: Desh Raj 2 Contrastive Predictive Coding and Mutual Information In representation learning, we are interested in learning a (possibly stochastic) network h: X!Y that maps some data x 2Xto a compact representation h(x) 2Y. For ease of notation, we denote p(x) as the data distribution, p(x;y) as the joint distribution for data and representations Contrastive Predictive Coding. Contrastive Predictive Coding (CPC, van den Oord et al., 2018) is a contrastive method that can be applied to any form of data that can be expressed in an ordered sequence: text, speech, video, even images (an image can be seen as a sequence of pixels or patches).

Aaron van den Oord, Yazhe Li, Oriol Vinyals [Google DeepMind] [Submitted on 10 Jul 2018 (v1), last revised 22 Jan 2019 (this version, v2)] arXiv:1807.03748 The goal of unsupervised representation learning is to capture semantic information about the world, recognizing patterns in the data without using annotations. This paper presents a new method called Contrastive Predictive Coding (CPC) that can do so across multiple applications. The main ideas of the paper are: Contrastive Predictive Coding (CPC) learns self-supervised representations by predicting the future in latent space by using powerful autoregressive models. The model uses a probabilistic contrastive loss which induces the latent space to capture information that is maximally useful to predict future samples.
