Parallelized Rate-Distortion Optimized Quantization Using Deep Learning

no code implementations11 Dec 2020 Dana Kianfar, Auke Wiggers, Amir Said, Reza Pourreza, Taco Cohen

We train two classes of neural networks, a fully-convolutional network and an auto-regressive network, and evaluate each as a post-quantization step designed to refine cheap quantization schemes such as scalar quantization (SQ).

Predictive Sampling with Forecasting Autoregressive Models

no code implementations ICML 2020 Auke Wiggers, Emiel Hoogeboom

Autoregressive models (ARMs) currently hold state-of-the-art performance in likelihood-based modeling of image and audio data.

Simulating Execution Time of Tensor Programs using Graph Neural Networks

no code implementations26 Apr 2019 Jakub M. Tomczak, Romain Lepert, Auke Wiggers

Optimizing the execution time of tensor program, e. g., a convolution, involves finding its optimal configuration.
