  1. new HitRatio(k: Int = 10, negNum: Int = 100)(implicit arg0: ClassTag[T], ev: TensorNumeric[T])

    k

    top k.

    negNum

    number of negative items.

  4. def apply(output: Activity, target: Activity): ValidationResult

    Output and target should belong to the same user.

    Output and target should belong to the same user. And have (negNum + 1) elements. Target should have only one positive label, means one element is 1, others are all 0. A couple of output and target will be count as one record.
