  • object ALS extends DefaultParamsReadable[ALS] with Logging with Serializable

    An implementation of ALS that supports generic ID types, specialized for Int and Long.

    An implementation of ALS that supports generic ID types, specialized for Int and Long. This is exposed as a developer API for users who do need other ID types. But it is not recommended because it increases the shuffle size and memory requirement during training. For simplicity, users and items must have the same type. The number of distinct users/items should be smaller than 2 billion.
