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 ...

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.

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).

An Introduction to the WEKA Data Mining System - CCSU

• K-nearest neighbor (KNN, IBk) Take the class of the nearest neighbor or the majority class among K neighbors K=1 -> no K=3 -> no K=5 -> yes K=14 -> yes (Majority predictor, ZeroR) • Distance is calculated as the number of different attribute values • Euclidean distance for numeric attributes • Weighted K-nearest neighbor K=5 -> undecided

DetCo: Unsupervised Contrastive Learning for Object Detection

learning and online clustering, e.g. MoCo v1/v2 [19,5], BYOL [18], and SwAV [3], have achieved great progress to bridge the performance gap between unsupervised and fully-supervised methods for image classification. How-ever, their transferring ability on object detection is not sat-isfactory. Concurrent to our work, recently DenseCL [39],
