Flashlight is a fast, flexible machine learning library written entirely in C++.
Native support in C++ and simple extensibility makes Flashlight a powerful research framework that enables fast iteration on new experimental setups and algorithms with little unopinionation and without sacrificing performance
Flashlight provides apps for research across multiple domains: Automatic speech recognition (formerly wav2letter project), Image classification, Object detection, and Language modeling.
This is free and open source software.
Key Features
- Total internal modifiability including internal APIs for tensor computation.
- A small footprint, with the core clocking in at under 10 MB and 20k lines of C++.
- High-performance defaults featuring just-in-time kernel compilation with modern C++ via the ArrayFire tensor library.
- An emphasis on efficiency and scale.
