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). Y) is the Wasserstein Predictive Coding J WPC [29] . These objectives maximize the distribution divergence between P XY and P XP Y, where we summarize them in Table1. Prior work [2, 36] theoretically show that these self-supervised contrastive learning objectives leads to the representations that can work well on downstream tasks.
(간만에 포스팅할 수 있는 논문을 읽을 수 있는 시간이 생겨 좋았다..ㅎ) 신경과학적으로 인간의 뇌는 다양한 추상적인 레벨의 관점에서 관찰한다고 한다. 최근 이것을 모티브로 삼아 predictive coding을 많이 사용하게 된다. 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.

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 key insight of our model is to learn such representations by predicting the future in latent space by using powerful autoregressive models. Contrastive losses and predictive coding were already used in different ways but not combined together (to make contrastive predictive coding, CPC). 3. Experiments. The authors experimented on 4 topics: audio, NLP, vision and reinforcement learning. 3.1.
