- Abstract summary: Softmax mechanism forces a model to predict an object class out of a set of pre-defined labels.
This characteristic contributes to efficacy in classification, but poses a risk of non-sense prediction in object recognition.
Open-Set Recognition is intended to address an issue of identifying a foreign object in object recognition.

- Abstract: This study investigates an application of a new probabilistic interpretation
of a softmax output to Open-Set Recognition (OSR). Softmax is a mechanism
wildly used in classification and object recognition.
However, a softmax mechanism forces a model to operate under a closed-set
paradigm, i.e., to predict an object class out of a set of pre-defined labels.
This characteristic contributes to efficacy in classification, but poses a
risk of non-sense prediction in object recognition.
Object recognition is often operated under a dynamic and diverse condition.
A foreign object -- an object of any unprepared class -- can be encountered
at any time.
OSR is intended to address an issue of identifying a foreign object in object
recognition.
Based on Bayes theorem and the emphasis of conditioning on the context,
softmax inference has been re-interpreted.
This re-interpretation has led to a new approach to OSR, called Latent
Cognizance (LC). Our investigation employs various scenarios, using Imagenet
2012 dataset as well as fooling and open-set images. The findings support LC
hypothesis and show its effectiveness on OSR.

Anomaly detection algorithms for feature-vector data identify anomalies as outliers, but outlier detection has not worked well in deep learning.
This paper proposes the Familiarity Hypothesis that these methods succeed because they are detecting the absence of familiar learned features rather than the presence of novelty.
The paper concludes with a discussion of whether familiarity detection is an inevitable consequence of representation learning.

In open set recognition, a classifier has to detect unknown classes that are not known at training time.
Recently proposed Capsule Networks have shown to outperform alternatives in many fields, particularly in image recognition.
In our proposal, during training, capsules features of the same known class are encouraged to match a pre-defined gaussian, one for each class.
