Neural Information Processing Systems

The softmax is the standard transformation used in machine learning to map real-valued vectors to categorical distributions.








Self-training Avoids Using Spurious Features Under Domain Shift Yining Chen, Colin Wei

Neural Information Processing Systems

For this setting, we prove that entropy minimization on unlabeled target data will avoid using the spurious feature if initialized with a decently accurate source classifier, even though the objective is non-convex and contains multiple bad local minima using the spurious features.
