WebNov 7, 2024 · My optimizer needs w (current parameter vector), g (its corresponding gradient vector), f (its corresponding loss value) and… as inputs. This optimizer needs many computations with w, g, f inside to give w = w + p, p is a optimal vector that my optimizer has to compute it by which I can update my w. WebFeb 1, 2024 · timm.optim.Lookahead(optimizer, alpha=0.5, k=6) When using Lookahead, we need to update our training script to include the following line, to update the slow weights. optimizer.sync_lookahead() An example of how this can be used is demonstrated below:

WebFeb 23, 2024 · 1. As Richard mentions, you can use cross validation. Another option which does not require that you do a K-fold cross-validation is generalized cross validation. See e.g., the smooth.spline function in R or the mgcv package in R (and the book by Simon Wood). Particularly, see the H argument in the gam function in the mgcv package.
