The value of out-of-distribution data
Generalization error always improves with more in-distribution data. However, it is an open
question what happens as we add out-of-distribution (OOD) data. Intuitively, if the OOD data …

Approximately optimal domain adaptation with Fisher's Linear Discriminant Analysis
We propose a class of models based on Fisher's Linear Discriminant (FLD) in the context of
domain adaptation. The class is the convex combination of two hypotheses: i) an average …
