Noise-contrastive estimation: A new estimation principle ...

ated noise y. The estimation principle thus relies on noise with which the data is contrasted, so that we will refer to the new method as “noise-contrastive estima-tion”. In Section 2, we formally define noise-contrastive es-timation, establish fundamental statistical properties, and make the connection to supervised learning ex-plicit.

Self-Attention Generative Adversarial Networks

Self-Attention Generative Adversarial Networks Figure 1. The proposed SAGAN generates images by leveraging complementary features in distant portions of the image rather than local regions of fixed shape to generate consistent objects/scenarios. In each row, the first image shows five representative query locations with color coded dots.

Deep Gaussian Processes

representational power of a Gaussian process in the same role is significantly greater than that of an RBM. For the GP the corresponding likelihood is over a continuous vari-able, but it is a nonlinear function of the inputs, p(yjx) = N yjf(x);˙2; where N j ;˙2 is a Gaussian density with mean and variance ˙2. In this case the likelihood is ...

Gender Shades: Intersectional Accuracy Disparities in ...

117 million Americans are included in law en-forcement face recognition networks. A year-long research investigation across 100 police de-partments revealed that African-American indi-viduals are more likely to be stopped by law enforcement and be subjected to face recogni-tion searches than individuals of other ethnici-ties (Garvie et al.,2016).

Dense Contrastive Learning for Self-Supervised Visual Pre ...

• We propose a new contrastive learning paradigm, i.e., dense contrastive learning, which performs dense pair-wise contrastive learning at the level of pixels (or local features). • With the proposed dense contrastive learning, we de-sign a simple and effective self-supervised learning method tailored for dense prediction tasks, termed

DetCo: Unsupervised Contrastive Learning for Object Detection

In this work, we present DetCo, which is a contrastive learning framework beneficial for instance-level detection tasks while maintaining competitive image classification transfer accuracy. DetCo contains (1) multi-level supervi-sion on features from different stages of the backbone net-work. (2) contrastive learning between global image and

Self-supervised visual representation learning. In com-puter vision, contrastive learning [19] has become increas-ingly successful for self-supervised learning, e.g., [45,34, 22,2,20,10]. The methodology is to learn representa-tions that attract similar (positive) samples and dispel dif-ferent (negative) samples. The representations from con-
