Recommendation - Algorithm by mahout

No algorithm description given

Overview Eventually we will expand this to allow different parameters and options for neighborhood and similarity functions. One of the more convenient datasets is the MovieLens 100k dataset at http://www.grouplens.org/system/files/ml-100k.zip . More detailed documentation can be found at https://mahout.apache.org/users/recommender/recommender-documentation.html Sample Input The sample input used below (movies.csv) has the following format: userId, itemId, reviewPoints 196,242,3 186,302,3 22,377,1 244,51,2 ... Information about Modes User-based recommendation In this mode, the recommender returns a set of item recommendations for each user, along with the predicted rating for the item. Think of this as generating recommendations based on user similarity. Item-based recommendation This returns, for each item, a list of similar items. Matrix Factorization recommendation (with Alternating Least Squares) An alternate and often more effective approach to recommendation that can be useful for uncovering latent explanatory factors. We plan to expose more of this soon, meanwhile, it acts as a user-based recommender. Upcoming Features We plan to add ALS on implicit feedback and weighted matrix factorization soon.

Internet access

This algorithm has Internet access. This is necessary for algorithms that rely on external services, however it also implies that this algorithm is able to send your input data outside of the Algorithmia platform.

To understand more about how algorithm permissions work, see the permissions documentation.
