The importance of the online store
• Primary source of income in the future
• Great company presentation
• Serves unlimited amount of people
• Potentially costs less with significantly better impacts

Collaborative filteringNeighbor-based algorithms
Calculates the similarity between two objects
• User-based algorithm
• Find users who share the same rating patterns with the active user and calculate a
prediction
• Item-based algorithm
• Build a matrix of items determining relationships between pairs

Memory based Model based

Memory based approach

In user based approaches, the value of ratings user u gives to item i is calculated as an aggregation of some similar users' rating of the item where U denotes the set of top N users that are most similar to user u
who rated item i
