And I'm struggling to fix this dilemma. I'm aware that this is not 1-day-change. Has anybody experienced feeling like this ? I'd to read your story. And I'll more than grateful for any suggestions/ideas how to overcome this situation.
A few weeks ago I started reading "Programming Collective Intelligence" by Toby Segaran [1] and I think it was a very good start to learn about the subjects mentioned in the title.
It puts nicely theory into practice and everything is quite easy to understand so it's a great introduction, but I'd like to learn more :)
Can you suggest any other good and intelligible books on topics such as recommendations, filtering, similarities, clustering etc.?
