This paper proposes a region mutual information (RMI) loss to model the dependencies among pixels. RMI uses one pixel and its neighbor pixels to represent this pixel. Then for each pixel in an image, we get a multi-dimensional point that encodes the relationship between pixels, and the image...
This repo contains a Pytorch implementation of MINE and a reconstruction of most of the experiments Currently this includes: Comparing MINE to non-parametric estimation Capturing non-linear dependencies Maximizing mutual information to improve GANs ...
Overview of GeneVector framework starting from single cell read counts. Mutual information is computed on the joint probability distribution of read counts for each gene pair. Each pair is used to train a single layer neural network where the MSE loss is evaluated from the model output (w1Tw2)...

for mining the useful information such that the relation features and region features are adaptively fused. We design a multi-task loss to train the model, especially, a regularization term is adopted to incorporate the prior knowledge about the relations into the graph. A data augmentation method...
All of the experiments are implemented using the Pytorch framework. Conclusion On training deep neural networks, large-scale datesets are essential, and they are often annotated manually, which is time-consuming and ineffective. So, it is necessary to explore how to utilize massive noisy data to...

Note: we have found some differences in performance based on the Pytorch version used, notably 0.4.1 and 1.0. We have found these differences independently with a separate codebase, and these may effect experiment outcomes with the NCE loss and NDM. Please report any discrepancies you find, as...
