今天我们就讲一种既能压缩模型大小,又能加速模型推断速度:量化。 量化一般可以分为两种模式:训练后的量化(post training quantizated)和训练中引入量化(quantization aware training)。 训练后的量化理解起来比较简单,将训练后的模型中的权重由float32量化到int8,并以int8的形式保存,但是在实际推断时,还需要反量化为f...

Among the compression techniques, this paper proposes quantization aware training in 8-bit low precision setting. Further we will introduce our implementation of fake quantization during training and inference of a deep neural network in 8-bit setting and its performance improvements over the ...
Several post-training quantization methods have been applied to large language models (LLMs), and have been shown to perform well down to 8-bits. We find that these methods break down at lower bit precision, and investigate quantization aware training for LLMs (LLM-QAT) to push quantization ...
While extensive research has focused on weight quantization, quantization-aware training (QAT), and their application to SNNs, the precision reduction of state variables during training has been largely overlooked, potentially diminishing inference performance. This paper introduces two QAT schemes for ...
The whitepaper also mentions that PTQ alone may not be sufficient to overcome errors introduced with low-bit width quantization in some models. Developers can employ AIMET’s Quantization-Aware Training (QAT) functionality, when the use of lower-precision integers (e.g., 8-bit) causes a large...
In this work, we explore the viability of training quantized GNNs models, enabling the usage of low precision integer arithmetic during inference. We identify the sources of error that uniquely arise when attempting to quantize GNNs, and propose a method, Degree-Quant, to improve performance over...
Official PyTorch implement of paper EfficientQAT: Efficient Quantization-Aware Training for Large Language ModelsNews[2024/10] 🔥 We release a new weight-activation quantization algorithm, PrefixQuant, which is the first work to let the performance of static activation quantization surpasses dynamic one...
Illustrations of the key concepts of the paper: Periodic scheduling can enable SNNs to overcome flat surfaces and local minima. When the LR is boosted during training using a cyclic scheduler, it is given another chance to reduce the loss with different initial conditions. While the loss appears...
