Anchors

ExpyBox.anchors()

Create dialog for Anchors

Returns

None

Method parameters

• threshold

  Minimum precision threshold for anchor rules.

• delta

  Used to compute beta. The lower the value, the higher the beta parameter for beam search (wider beam) is. You can see how exactly beta is computed here.

• tau

  Margin between lower confidence bound and minimum precision or upper bound. Here tau is used in place of delta from IML book or the Anchros paper.

• batch size

  Batch size used for sampling

• discretizer percentiles

  Iterable with percentiles (ints) used for discretization of ordinal features. If None, [25, 50, 75] will be used. Here you need specify the name of the variable with list of percentiles that is in the kernel_globals parameter that you passed to ExpyBox.
