However, it is impossible to evaluate the hidden representation on all those tasks; moreover, due to relationship between tokens (Hu et al., 2016) in Y, not all partitions are reasonable.
motivated by the analysis of VC Dimension (Vapnik, 1995), we construct a sequence of nested partitions with an entailment structure: The benefit is that a spectrum of task hardness can be constructed due to the increased partition or task cardinalities.
