Characterizing Structural Regularities of Labeled Data in Overparameterized Models

1 code implementation8 Feb 2020 Ziheng Jiang, Chiyuan Zhang, Kunal Talwar, Michael C. Mozer

We obtain empirical estimates of this score for individual instances in multiple data sets, and we show that the score identifies out-of-distribution and mislabeled examples at one end of the continuum and strongly regular examples at the other end.
