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.

The key insight of our model is to learn such representations by predicting the future in latent space by using powerful autoregressive models. Figure 1: Overview of Contrastive Predictive Coding, the proposed representation learning approach. Although this figure shows audio as input, we use the same setup for images, text and reinforcement learning. 2 Contrastive Predicting Coding We start this section by motivating and giving intuitions behind our approach.

The key insight of our model is to learn such representations by predicting the future in latent Representation Learning with Contrastive Predictive Coding. Contrastive Predictive Coding (CPC) is proposed in (Oord, Li, and Vinyals,. 2018) as a new unsupervised representation learning framework.

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:
