Web Machine Learning

Web Neural Network (WebNN) API polyfill and examples

A polyfill for Web Neural Network (WebNN) API with computer vision and natural language processing examples.

The Web Neural Network (WebNN) API is a dedicated low-level API for neural network inference hardware acceleration. It is worked on in the W3C Machine Learning for the Web Community Group.

Project Build Status
