Intuitively, when we force the samples to have highest entropy, OOD samples. are closer to the uniform distribution (zero confidence). A sample WebOOD generalization is a very difficult problem. Instead of tackling it head on, this talk argues that, when considering the current strengths and weaknesses of deep learning, we should consider an alternative approach which tries to dodge the problem altogether. ...
