The MovieLens data sets are popular data sets for building recommendation models in research, education and development. The dataset (ml-latest-small) used in this demonstration contains 100,004 5-star ratings across 9125 movies created by 671 users between 9 January 1995 and 16 October 2016. The dataset records the userId, movieId, rating, timestamp, title, and genres. The goal is to build a recommendation model to recommend new movies to users.
This pre-built model has used the R language to build a recommendation model to represent the knowledge discovered using a Smart Adaptive Recommendations (SAR) algorithm. The knowledge representation is easy to understand.
The demo command applies the pre-built model to a demo data set with records from 10 users and shows the recommendation results for 2 users.
The print command will display a textual summary of the model and its build parameters.
The score command applies the pre-built model to a supplied data set and shows the recommendation results for 2 users. Example score command:
$ ml score movies user10.csv
