Abstract Nowadays the use of computational vision methods on real-world problems is growing mainly by the achievement of better results on image and video recognition tasks. These results have been achieved by the evolution of machine learning methods, specifically by deep neural networks. However, these methods are usually adapted for tasks where their limits are well known, and have low flexibility for data that have been out of the problem scope. In real-world problems, we expect that classification methods should achieve equivalent results of the training step. But when used on these problems, we can see low classification performance. This happens by the fact that deep networks do not generalize well on unknown data or domain different data, which is known as category shift and domain shift problems. In front of this problem, researchers have been developing methods to avoid this gap with unknown data on two main research lines: Unsupervised domain adaptation methods and Open-set methods, also known by open-world methods. While domain adaptation methods try to align domain distributions, open-set methods should predict if some data can be recognizable by the network. The goal of this work is to study and investigate open-set methods and develop new state-of-art approaches on images and video recognition tasks. (AU) | |
