Generative Pretraining from Pixels - OpenAI

Generative Pretraining from Pixels (Radford et al.,2019) formulation of the transformer de-coder block, which acts on an input tensor hlas follows: nl= layer norm(hl) al= hl+multihead attention(nl) hl+1 = al+mlp(layer norm(al)) In particular, layer norms precede both the attention and

Time-series Generative Adversarial Networks - NIPS

TimeGAN is a generative time-series model, trained adversarially and jointly via a learned embedding space with both supervised and unsupervised losses. As such, our approach straddles the intersection of multiple strands of research, combining themes from autoregressive models for sequence prediction,

This leads to more consistent image synthesis results, e.g. note how, in contrast to our method, translating one object might change the other when operating in 2D (Fig. 2a and 2b). It further allows us to perform complex ...

Latent Dirichlet allocation (LDA) is a generative probabilistic model of a corpus. The basic idea is that documents are represented as random mixtures over latent topics, where each topic is charac-terized by a distribution over words.1 LDA assumes the following generative process for each document w in a corpus D: 1. Choose N ˘Poisson(ξ). 2.

The field of generative models has made tremendous progress in the last few years. One of the aims of gen-erative modeling is to capture the salient aspects of the data and to generate new instances indistinguishable from the true data The hypothesis is that by learning to produce the data we can learn the best features of the data1.
