Characterizing Structural Regularities of Labeled Data in Overparameterized Models

Jiang, Ziheng, Zhang, Chiyuan, Talwar, Kunal et al.

Understand

Humans are accustomed to environments that contain both regularities and exceptions.

  • For example, at most gas stations, one pays prior to pumping, but the occasional rural station does not accept payment in advance.
  • Likewise, deep neural networks can generalize across instances that share common patterns or structures, yet have the capacity to memorize rare or irregular forms.
  • We analyze how individual instances are treated by a model via a consistency score.
