Recent Hot Machine Learning Hammers used in Computer Vision

I will describe a few techniques that are widely used in computer vision these days and I consider them hot methods. There is no standard tool for measuring whether a method is hot or not, and this is solely based on my personal judgement as a researcher who is attending computer vision conferences and is actively publishing in this area. I consider a method to be hot when in one year it appears in tens of papers, and one can observe researchers talking about it during the main conferences of the field. In the following sections I describe three class of methods that I believe are hot these days. Note that hundreds of papers use the method presented in each of these sections and it is impractical to mention all of them in this article. As a result I only mention a few papers that best represent each of the methods.
