An Informal DefinitionRecommender systems is a family of methods that enable filtering through large observation and information space in order to provide recommendations in the information space that user does not have any observation, where the information space is all of the available items that user could choose or select and observation space is what user experienced or observed so far. Why it is necessaryWe have more options and choices that what we used to have and this increase in options and choices will even increase in the near future. Watch Jack Irish: Bad Debts Megavideo. 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 recommendationsword of mouth, forums, blog posts or reviews or expert advicecolumnist, 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 preferencenaturally 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. Industry UsageIn industry, considering the usage, the most widely known recommender system could be attributed to Amazon.

Currently, many companies that sell a selection of products and have access to user information, employ a recommender system that promotes futher purchases to the user. Richness of the EcosystemDifference business and product needs and a variety of algorithms that could be used for recommender systems yielded a rich set of methods that could be used for recommendations. Connection to Information RetrievalThis subsection of machine learning methods also have connections with information retrieval and actually the problem could be formulated as an information retrieval problem as well. Consider Google, the linksitems are brought to the first page to the users based on query information, location, user history and so on. Therefore, most of the algorithms invented in information retrieval could be adopted to recommendation systems with minimal changes. The reverse may not hold true in general, though. In this post, I will focus mainly on Collaborative Filtering in these set of algorithms. This page was last modified on 3 October 2017, at 1417. This page has been accessed 180,780 times.
