Task: Summarization
Input (English): Training with larger number of parameters while keeping fast iterations is an increasingly
 adopted strategy and trend for developing better performing Deep Neural
 Network (DNN) models. This necessitates increased memory footprint and
 computational requirements for training. Here we introduce a novel methodology
 for training deep neural networks using 8-bit floating point (FP8) numbers.
 Reduced bit precision allows for a larger effective memory and increased computational
 speed. We name this method Shifted and Squeezed FP8 (S2FP8). We
 show that, unlike previous 8-bit precision training methods, the proposed method
 works out of the box for representative models: ResNet50, Transformer and NCF.
 The method can maintain model accuracy without requiring fine-tuning loss scaling
 parameters or keeping certain layers in single precision. We introduce two
 learnable statistics of the DNN tensors - shifted and squeezed factors that are used
 to optimally adjust the range of the tensors in 8-bits, thus minimizing the loss in
 information due to quantization.
Output (English): We propose a novel 8-bit format that eliminates the need for loss scaling, stochastic rounding, and other low precision techniques
