Trax
Trax is a deep learning framework and hardware-agnostic tensor engine designed for designing and training neural networks. It serves as a research tool providing high-level combinators for composing complex architectures, alongside a dedicated library for building transformer models and a toolkit for reinforcement learning.
The framework is distinguished by its support for reversible and sparse transformer architectures, which reduce memory and computational overhead. It enables a single set of model instructions to execute across different hardware backends without changing the underlying code.
The system covers a broad range of capabilities, including automatic gradient computation, supervised model training, and data stream preprocessing. It supports the implementation of various network topologies such as residual networks and transformer encoders for applications in natural language processing, visual content generation, and actor-critic reinforcement learning.
