I am currently trying to learn pattern recognition from Pattern Classification by Duda et al. However, this books is a bit too dense for me. I keep hitting walls while trying to read the books (I understand most of the reasoning, but it just becomes too much and too abstract). Can anybody recommend a book that eases you in more? Or, gives more intuitive explanations of the results? I am trying to get through the first five chapters of the second edition of the book.
