Ideas for 2026 updates

A few ideas that Akila and I came for to improve the U-Net exercise for 2026:

• add a simple extra exercise in the beginning to show the concept of a Class (for example: UpSample), this will make the next exercises easier
• split Task-6 into two parts, because this task is the main bottleneck of the entire exercise, mainly because the calculations of the number of fmaps is complicated. Proposed order:
  1. make a function that computes the number of fmaps given a set of input parameters. Also, provide a test function to test their implementation
  2. then, implement the full training loop.
• provide a function to derive the receptive field, given a network (see Function for computing valid input sizes #9?)
• Task4: add the hint to print shapes, this helps solving the problem
• style: we could add little images per task, to visually indicate which part of the large U-Net this respective task implements
