Representation Learning with Contrastive Predictive Coding 论文链接：https://arxiv.org/abs/1807.03748 1 Introduce 作者提出了一种叫做“对比预测编码（CPC, Contrastive Predictive Coding）”的无监督方法，可以从高维数据中提取有用的 representation，这种 representation 学习到了对预测未来最有用的信息。

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:

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. 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.

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.
