Hello, everyone !
My demand is a optical-flow-generating problem. I have two raw images and a optical flow data as ground truth, now my algorithm is to generate optical flow using raw images, and the euclidean distance between generating optical flow and ground truth could be defined as a loss value, so it can implement a backpropagation to update parameters.
I take it as a regression problem, and I have to ideas now:
I can set every parameters as (required_grad = true), and compute a loss, then I can loss.backward() to acquire the gradient, but I don’t know how to add these parameters in optimizer to update those.
I write my algorithm as a model. If I design a “custom” model, I can initilize several layers such as nn.Con2d(), nn.Linear() in def init() and I can update parameters in methods like (torch.optim.Adam(model.parameters())), but if I define new layers by myself, how should I add this layer’s parameters in updating parameter collection???
This problem has confused me several days. ,are there any good methods to update user-defined parameters ? I would be very grateful if you could give me some advice !
