Web13 de mar. de 2024 · Loss scaling can prevent the divergence during mixed-precision training. This can be achieved by scaling the loss values computed in the forward propagation using a loss scaling factor S, prior to starting backward propagation. WebQuantization is the process to convert a floating point model to a quantized model. So at high level the quantization stack can be split into two parts: 1). The building blocks or abstractions for a quantized model 2). The building blocks or abstractions for the quantization flow that converts a floating point model to a quantized model.
