Original Abstract:

There has been an explosion of interest in designing high-performanceTransformers. While Transformers have delivered significant performanceimprovements, training such networks is extremely memory intensive owing tostoring all intermediate activations that are needed for gradient computationduring backpropagation, especially for long sequences. To this end, we presentMesa, a memory-saving resource-efficient training framework for Transformers.Specifically, Mesa uses exact activations during forward pass while storing alow-precision version of activations to reduce memory consumption duringtraining. The low-precision activations are then dequantized duringback-propagation to compute gradients. Besides, to address the heterogeneousactivation distributions in the multi-head self-attention layers, we propose ahead-wise activation quantization strategy, which quantizes activations basedon the statistics of each head to minimize the approximation error. To furtherboost training efficiency, we learn quantization parameters by runningestimates. More importantly, by re-investing the saved memory in employing alarger batch size or scaling up model size, we may further improve theperformance under constrained computational resources. Extensive experiments onImageNet, CIFAR-100 and ADE20K demonstrate that Mesa can reduce half of thememory footprints during training while achieving comparable or even betterperformance.

Context On This Paper:

– Mesa is a memory-saving training framework for Transformers in machine learning.- It reduces memory consumption during training by using low-precision activations and head-wise activation quantization.- Mesa can reduce half of the memory footprints during training while achieving comparable or better performance on ImageNet, CIFAR-100 and ADE20K.

 

Mesa is a game-changing training framework for Transformers, reducing memory consumption by half without compromising performance.

Flycer’s Commentary:

The latest research on Transformers has shown significant performance improvements, but training these networks can be extremely memory intensive. This is where Mesa comes in, a memory-saving training framework for Transformers that uses exact activations during the forward pass while storing a low-precision version of activations to reduce memory consumption during training. This approach not only reduces memory footprints during training but also allows for a larger batch size or scaling up model size, which can further improve performance under constrained computational resources. Additionally, Mesa proposes a head-wise activation quantization strategy to minimize approximation error and learns quantization parameters by running estimates. The results of extensive experiments on ImageNet, CIFAR-100, and ADE20K demonstrate that Mesa can achieve comparable or even better performance while reducing half of the memory footprints during training. As a small business owner, implementing Mesa could help you train your AI models more efficiently and effectively, ultimately improving your business’s performance.
