WebJan 31, 2024 · The bias is an additive parameter in the convolution. It’s like the b in f (x) = w*x + b. If you set bias=False, you will drop the b term, which might make sense in some cases, e.g. if the next layer is an affine BatchNorm layer. Each kernel has an own bias term. However, I think the concept is way better described in Stanford’s CS231n. 4 Likes

WebOct 17, 2024 · Both bias and noise are additive. One important advantage of noise is that you can measure noise without knowing where the target was. When you remove the target, you have no idea if the measurement was accurate or not, but you can still see whether there was noise.
