Query-to-Query Similarity Job

Train a collaborative filtering matrix decomposition recommender using SparkML’s Alternating Least Squares (ALS) to batch-compute query-query similarities. This can be used for items-for-query recommendations as well as queries-for-query recommendations.

This job is deprecated as of Fusion 5.2.0. We recommend the use of the Query-to-Query Session-Based Similarity jobs instead for better performance and query coverage.
