Thus, it helps in reducing the overall loss and improving accuracy. The problem of choosing the right weights for the model is a daunting task, as a deep learning model generally consists of millions of parameters.

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. circularity psychology definition
