State-of-the-art generic low-precision training algorithms use a mix of 16-bit and 32-bit precision, creating the folklore that 16-bit precision alone is not enough to maximize model accuracy. As a result, deep learning accelerators are forced to support both 16-bit and 32-bit compute unit...
(32-bit SIMD). The additional support is designed to be used for both machine learning inference and training across Arm-based clients and servers. While the Arm server space is still tiny, its client footprint is enormous, which means that future generation of hand-held and IoT device will...
This paper presents the first comprehensive empirical study demonstrating the efficacy of the Brain Floating Point (BFLOAT16) half-precision format for Deep Learning training across image classification, speech recognition, language modeling, generative networks and industrial recommendation systems.
