WebThe SwinV2 paper also proposes to change the pre-layernorm to a post-layernorm for further stability. I have validated that this works just as well as dot product attention in an autoregressive setting, if one were to initialize the temperature as proposed in the QK-norm paper (as a function of the sequence length). WebDequantized FP32 tensors should not deviate too much from the pre-quantized FP32 tensor.
