Alternating Least Squares Method for Collaborative Filtering. An Informal Definition. What to eat, which movie to watch, what book to read are the questions that we find ourselves to answer all the time. If you just consider the infromation space that has the answer of these questions let alone the answering the questions in the first place, you could find yourself in an immmense decision domain, which may cripple your decision making. Traditionally, this questions are answered with peer recommendations(word of mouth, forums, blog posts or reviews) or expert advice(columnist, librarian and recommendation of someone who has domain expertise). Traditional methods are good but limited in the observation spaces that recommenders have to begin with. Your peers could only read so many books, could only visit so many restaurans, could only watch so many movies. Second, they are biased towards their preference(naturally) where when you want to make a decision, you want to be biased towards yourself in order to maximize the decision outcome. Third, a person may not have access to these traditional methods. She may not have peers who share somehow same taste in music and movies, she may not have access reading expert advices. Due to these shortcomings, computer based recommender systems provide a much better alternative to the user. Not only they do not have these shortcomings of the traditional methods, but also they could mine the historical information of the user and demographics information which may result in a more accurate and finely- tuned recommendation for a problem that what traditional methods could offer.

Consider Google, the links(items) are brought to the first page to the users based on query information, location, user history and so on.
