Startup Arya.ai on Monday introduced Braid, an open source tool available for free to companies developing neural networks. Braid is a flexible, customizable, modular meta-framework that works with operating systems for deep learning. It is designed for rapid development and to support arbitrary network designs. It is simple and scalable, for use with networks that need to handle many data points at large volume, Arya.ai said. Braid allows for quick experimentation without having to worry about the boilerplate components of the code.
