WebJul 21, 2024 · I think this is the hack from FixUp Initialization. Where you initialize the last layers to zero, so that they do not contribute initially to the loss term, basically a way to make gradients flow to initial layers rather than the last layer learning everything. 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. dauphin county pennsylvania genealogy
