Quantization - Neural Network Distiller (intellabs.github.io) 假设数据的激活值分布服从高斯分布或者拉普拉斯分布,那么我们可以根据需要选取合适的分布参数来适配2,3,4等bits的量化。例如以拉普拉斯分布的参数b为例,我们可以|r_{max}|设为2.83b,3.89b,5.03b以适配2,3,4bits的量化,而由于超出裁剪范围的数据出现...
2. Full integer quantization. This is a static quantization. 静态量化之于动态量化的最大区别是静态量化需要representative dataset,这是因为model input和activation是variable tensors,在calibrate它们时需要事先run a few inference cycles才能确定ranges (min, max),而对于weights和biases来说,它们是constant tensor...

In the generated model_int8.tflite, the constant_values tensor is correctly quantized to int8. However, in model_int16.tflite the constant_values tensor is not quantized at all and remains a float32 tensor after conversion. Eventually, this causes a runtime error during inference. The expect...

Objective: My primary goal is to accelerate my model's performance using int8 + fp16 quantization. To achieve this, I first need to quantize the model and then calibrate it. As far as I understand, there are two quantization methods avai...
