Machine learning algorithms in recommender systems are typically classified into two categories — content based and collaborative filtering methods although modern recommenders combine both.. A recommender system, or a recommendation system (sometimes replacing 'system' with a synonym such as platform or engine), is a subclass of information filtering system that seeks to predict the rating or preference a user would give to an item. They are primarily used in commercial applications The most commonly used recommendation algorithm follows the people like you, like that logic. We call it a user-user algorithm because it recommends an item to a user if similar users liked this item before. The similarity between two users is computed from the amount of items they have in common in the dataset A recommendation engine (sometimes referred to as a recommender system) is a tool that lets algorithm developers predict what a user may or may not like among a list of given items

What are Recommendation Algorithms? Recommendation Algorithms - Algorithms that help machines suggest a choice based on their commonality with historical data. you decide to conduct a study on consumer behavior in shopping and take a survey of people who 'do not' enjoy shopping, there will only a meager percentage of them in the category; however, you take a headcount of people. When I first started playing with recommendation algorithms I was trying to produce novel results -- things that the user didn't know about and would be interesting to them, rather than using some of the more basic counting algorithms that are used e.g. for Amazon's related products. What I realized pretty quickly is that even I didn't trust the recommendations. They seemed disconnected, even. To experiment with recommendation algorithms, you'll need data that contains a set of items and a set of users who have reacted to some of the items. The reaction can be explicit (rating on a scale of 1 to 5, likes or dislikes) or implicit (viewing an item, adding it to a wish list, the time spent on an article). While working with such data, you'll mostly see it in the form of a matrix.

Recommendation Algorithms It is possible to make complex queries in Neo4j using Cypher, but when talking about graph algorithms, there are libraries like Python NetworkX and R igraph that covers a lot more ground.
