We conclude that local and online learning is important to capture the full dynamics of open world recognition. ...
Recent attempts, like the open world recognition framework, tried to inject dynamics into the system by detecting new unknown classes and adding them incrementally, while at the same time continuously ...
Still, all these methods estimate the used metric, and the threshold for novelty detection, on an initial closed set of classes, and keep the metric and threshold fixed as the problem evolves. ...

Correctly invalidating the prediction of unrelated classes is a challenging problem that has been tackled in many ways in the literature. ...
Novelty detection gives deep learning the ability to output "do not know" for novel/unseen classes. Still, no attention has been given to the security aspects of novelty detection. ...
A similar approach based on learning a local model around a test sample is pro-posed on [Bodesheim et al., 2015] for Multi-class novelty detection tasks in image recognition problems. ...
