These are used in the Glow paper to help with image understanding. Details can be found in their paper and aren't essential for understanding the flow-based modeling framework. The coupling allows for us to compute a Jacobian defined by a triangular matrix, which is significantly more efficient than would otherwise be possible.

Normalizing flows (NF) are a powerful framework for approximating posteriors. By mapping a simple base density through invertible transformations, flows provide an exact method of density evaluation and sampling. The trend in normalizing flow literature has been to devise deeper, more complex transformations to achieve greater flexibility. We propose an alternative: Gradient Boosted Flows (GBF ...

May 21, 2019 · Face decoding and reconstruction. We used the pre-trained VAE–GAN model described in Fig. 1 (with “frozen” parameters) to train a brain-decoding system. During training (Fig. 2a), the system learned the correspondence between brain activity patterns in response to numerous face images and the corresponding 1024-D latent representation of the same faces within the VAE network.

A recently developed generative flow model called Glow proposed to learn invertible 1 × 1 convolution to replace the fixed permutation and synthesize large photo-realistic images using the log-likelihood objective. We extend Glow to condition on high-dimensional input x, e.g. images, as shown in Fig. 1.

This bijector is identical to the "Convolution1x1" used in Glow (Kingma and Dhariwal, 2018).

Learning generative probabilistic models that can estimate the continuous density given a set of samples, and that can sample from that density, is one of the fundamental challenges in unsupervised machine learning. In this paper we introduce a new approach to obtain such models based on what we call denoising density estimators (DDEs). A DDE is a scalar function, parameterized by a neural ...

Non-autoregressive flow-based models (which we will refer to as “flow models”), such as NICE, RealNVP, and Glow, are efficient for sampling, but have so far lagged behind autoregressive models in density estimation benchmarks (Dinh et al., 2014, 2016; Kingma & Dhariwal, 2018). Modern generative models are usually designed to match target distributions directly in the data space, where the intrinsic dimensionality of data can be much lower than the ambient dimensionality. We argue that this discrepancy may contribute to the difficulties in training generative models. We therefore propose to map both the generated and target distributions to the latent space using the ...
