Oct 14, 2019 · In this section, we describe the quantization scheme, linear quantization, and quantization-aware training method we used. We chose to use this quantization scheme because, in addition to reducing the model size by approximately 4 ×, it is also possible to accelerate inference time by using Integer arithmetic to calculate GEMM using specialized hardware for Integer and Fixed Point calculations. progress in quantization-aware training has allowed the realization of results comparable to a baseline for as low as 2{4 bits per parameter [2, 9, 12, 24, 25] and show decent performance even for single bit (binary) parameters [13, 17, 22]. The major drawback of quantization-aware methods is the necessity for a vast amount of labeled data and ...
Quantization-aware training (for TensorFlow 1) uses "fake" quantization nodes in the neural network graph to simulate the effect of 8-bit values during training. Thus, this technique requires modification to the network before initial training. Quantization Aware Training: Uses fake quantization modules to store scales while training. For enabling QAT, we use the qconfig to be get_default_qat_qconfig('fbgemm') and instead of prepare use prepare_qat.After this, we can train or fine-tune our model and at the end of the training, get out the quantized model using torch.quantization.convert same as above.
In addition, we propose a quantization-overflow aware training framework for learning the quantization parameters, to minimize the performance loss caused by post quantization [Krishnamoorthi2018]. To verify the effectiveness of our method, we conducted tests on a couple of state-of-the-art light-weighted DNNs for a variety of tasks on ... Unlike quantization-aware training using the straight-through estimator that only targets a specific bit-width and requires access to training data and pipeline, our regularization-based method paves the way for ``on the fly’’ post-training quantization to various bit-widths.

Quantization-Aware Training. As mentioned above, in order to minimize the loss of accuracy from "aggressive" quantization, many methods that target INT4 and lower (and in some cases for INT8 as well) involve training the model in a way that considers the quantization. This means training with quantization of weights and activations "baked" into ...Overview. Welcome to an end-to-end example for quantization aware training.. Other pages. For an introduction to what quantization aware training is and to determine if you should use it (including what's supported), see the overview page.. To quickly find the APIs you need for your use case (beyond fully-quantizing a model with 8-bits), see the comprehensive guide.Retraining weights with quantization-in-the-loop is a useful technique to regain some lost accuracy. However the quantization thresholds are typically fixed after initial calibration, causing (a) lack of ability to adapt to changing weight and activation distributions during training, and (b) threshold calibration based on local quantization errors that is agnostic to global neural network loss.
