The main ideas of the paper are: This paper introduces Relative Predictive Coding (RPC), a new contrastive repre-sentation 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.

(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.

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 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.

Representation Learning with Contrastive Predictive Coding (Aaron van den Oord et al) (summarized by Rohin): This paper from 2018 proposed Contrastive Predictive Coding (CPC): a method of unsupervised learning that has been quite successful. Representation Learning with Contrastive Predictive Coding. 2018. Representation Learning with Contrastive Predictive Coding arxiv.org Contrastive Predictive Coding, as shown in figure 1, is unsupervised learning method with primary object is to learn high level information from predicting the representation of future or missing information of a sequential data. 无监督表示学习（一）：2018 Contrastive Predictive Coding(CPC) 今天看到了Hinton团队的一项无监督表示学习的新研究：SimCLR，其中总结了对比损失为无监督学习带来的飞速进展。于是决定把近三年来这方面的论文都读一下，2018、2019和2020每年各一篇，开始吧！监督式学习（Supervised learning），是机器学习中的一个方法，可以由标记好的训练集中学到或建立一个模式（函数 / learning model），并依此模式推测新的实例。训练集是由一系列的训练范例组成，每个训练范例则由输入对象（通常是向量）和预期输出所组成。 Representation Learning with Contrastive Predictive Coding 观测序列 ——非线性编码器 ——潜在表示序列潜在表示序列 ——自回归模型 ——上下文潜在表示（——观测值） Keras implementation of Representation Learning with Contrastive Predictive Coding for images - davidtellez/contrastive-predictive-coding-images.

Contrastive Predictive Coding (CPC) is proposed in (Oord, Li, and Vinyals,.

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.
