Neural Combinatorial Optimization with Reinforcement Learning In PyTorch

PyTorch implementation of Neural Combinatorial Optimization with Reinforcement Learning. I have implemented the basic RL pretraining model with greedy decoding from the paper. An implementation of the supervised learning baseline model is available here. Instead of a critic network, I got my results below on TSP from using an exponential moving average critic. The critic network is simply commented out in my code right now. From correspondence with a few others, it was determined that the exponential moving average critic […]

Molecular AutoEncoder in PyTorch

Molecular AutoEncoder in PyTorch Install $ git clone https://github.com/cxhernandez/molencoder.git && cd molencoder $ python setup.py install Download Dataset $ molencoder download –dataset chembl22 Train $ molencoder train –dataset data/chembl22.h5 Add –cuda flag to enable CUDA. Add –cont to continue training a model from a checkpoint file. Pre-Trained Model A pre-trained reference model is available in the ref/ directory. Currently, it performs with ~98% accuracy on the validation set after 100 epochs of training. However, if you succeed at training a […]

On the Effects of Batch and Weight Normalization in Generative Adversarial Networks

Code for the paper “On the Effects of Batch and Weight Normalization in Generative Adversarial Networks“. About the code Here two versions are provided, one for torch and one for PyTorch. The code used for the experiments in the paper was in torch and was a bit messy, with hand written backward pass of weight normalized layers and other staff used to test various ideas about GANs that are unrelated to the paper. So we decided to clean up the […]

Implementations of polygamma, lgamma, and beta functions for PyTorch

Implementations of polygamma, lgamma, and beta functions for PyTorch. It’s very hacky, but that’s usually ok for research use. To build, run: ./make.sh You’ll probably need to pass in the correct CUDA path to build.py, which is run inside make.sh, so modify it to instead call python build.py –cuda-path YOUR_CUDA_PATH Also, you’ll probably need to change the architecture version/CUDA compute capability inside make.sh, so replace sm_35 with whatever your GPU supports.Feel free to open an issue if you run into […]

Closing the generalization gap in large batch training of neural networks

Train longer, generalize better – Big batch training This is a code repository used to generate the results appearing in “Train longer, generalize better: closing the generalization gap in large batch training of neural networks” By Elad Hoffer, Itay Hubara and Daniel Soudry. It is based off convNet.pytorch with some helpful options such as: Training on several datasets Complete logging of trained experiment Graph visualization of the training/validation loss and accuracy Definition of preprocessing and optimization regime for each model […]

Topic modeling on unstructured data in Space news articles retrieved

NLP Space News Topic Modeling topic modeling on unstructured data in Space news articles retrieved from the Guardian (UK) newspaper using API Project Idea Project Overview This project aims to learn topics published in Space news from the Guardian (UK) news publication. Motivation The model/tool would give an idea of what Space news topics matter to each publication over time. For example, a space mission led by the European Space Agency (ESA) might be more relevant/important to the Guardian than […]

A Toastmasters-inspired speech timer for online scrum meetings

Qolor Tyme This is a Toastmasters-inspired speech timer for use during online daily scrum meeting updates. It is based on PyQt, which is Python API for Qt (pronounced “cute”) cross-platform GUI framework, hence the name Qolor Tyme. I honestly don’t know why they called it PyQt instead of QtPy, which would have made it “cutie-pie” ¯_(ツ)_/¯ Installation Use pip: pip install qolor-tyme Running Run it as the package. It accepts an optional timeout interval (default is 90 seconds per Agile […]

Robust Video Matting (RVM) in PyTorch

Official repository for the paper Robust High-Resolution Video Matting with Temporal Guidance. RVM is specifically designed for robust human video matting. Unlike existing neural models that process frames as independent images, RVM uses a recurrent neural network to process videos with temporal memory. RVM can perform matting in real-time on any videos without additional inputs. It achieves 4K 76FPS and HD 104FPS on an Nvidia GTX 1080 Ti GPU. The project was developed at ByteDance Inc.
