[DR016] What is wrong with convolutional neural nets?
This is a talk by Geoffrey Hinton at MIT in Dec, 2014. Four arguments against pooling, or more generally, CNN, are discussed. It is a bad fit to the psychology of shape perception: It does not explain why we assign intrinsic coordinate frames to objects and why they have such huge effects. For instance, people tend to use rectangular frames embedded in the objects. We use long side and short side for most of the time to express the orientation. Another conclusion is that we use a bunch of n... 1691
