Problem set 4: errata

  • Saturday 11/1: There was a slight bug in the 'boost_logistic' skeleton that we provided ('find_alpha' used 'H' that was never initialized, nor updated). It wasn't part of the problem to fill it in. The new version is available.

  • In question (2-5), the hint suggests that you select a part of a cell array as 'model{1:i}'. It should be 'model(1:i)'.

  • In (3-7) it is fine to assume that n=>m (we have more samples than components)

  • NOTE: (3-8) is canceled (has bugs)
