Spark Collaborative Filtering Learner
This node utilizes the Apache Spark collaborative filtering implementation.
Notice: The matrix factorization model contains references to Spark DataFrame/RDDs and thus is not selfcontained. The referenced Spark DataFrame/RDDs will be deleted, like any other Spark DataFrame/RDD generated in KNIME, when the node is reset, or when the workflow is closed and the "Delete Spark DataFrame/RDDs on dispose" option is enabled for the current Spark context.
- Type: Spark Data Spark DataFrame/RDD with user ratings of products
- Type: Spark Data The input data labeled with the prediction.
- Type: Spark Model The matrix factorization model. <b>The model is not selfcontained and thus can not be saved to file.</b>
