This paper presents a new contrastive representation learning objective - the Relative Predictive Coding (RPC). At a high level, RPC 1) introduces the relative parameters to regularize the objective for boundedness and low variance; and 2) achieves a good balance among the three challenges in the contrastive representation learning objectives: training stability, sensitivity to minibatch size

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. 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 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.
