Open Set Learning

91 papers with code • 0 benchmarks • 6 datasets

Traditional supervised learning aims to train a classifier in the closed-set world, where training and test samples share the same label space. Open set learning (OSL) is a more challenging and realistic setting, where there exist test samples from the classes that are unseen during training. Open set recognition (OSR) is the sub-task of detecting test samples which do not come from the training.

Towards Open Set Deep Networks

aadeshnpn/OSDN CVPR 2016

We present a methodology to adapt deep networks for open set recognition, by introducing a new model layer, OpenMax, which estimates the probability of an input being from an unknown class.

Learning a Neural-network-based Representation for Open Set Recognition

shrtCKT/opennet 12 Feb 2018

Open set recognition problems exist in many domains.

Unified Probabilistic Deep Continual Learning through Generative Replay and Open Set Recognition

MrtnMndt/OCDVAE_ContinualLearning 28 May 2019

Modern deep neural networks are well known to be brittle in the face of unknown data instances and recognition of the latter remains a challenge.

Generalized Out-of-Distribution Detection: A Survey

jingkang50/openood 21 Oct 2021

In this survey, we first present a unified framework called generalized OOD detection, which encompasses the five aforementioned problems, i. e., AD, ND, OSR, OOD detection, and OD.

OpenOOD: Benchmarking Generalized Out-of-Distribution Detection

jingkang50/openood 13 Oct 2022

Out-of-distribution (OOD) detection is vital to safety-critical machine learning applications and has thus been extensively studied, with a plethora of methods developed in the literature.

Query Attack via Opposite-Direction Feature:Towards Robust Image Retrieval

layumi/A_reID 7 Sep 2018

Opposite-Direction Feature Attack (ODFA) effectively exploits feature-level adversarial gradients and takes advantage of feature distance in the representation space.

Large-Scale Long-Tailed Recognition in an Open World

zhmiao/OpenLongTailRecognition-OLTR CVPR 2019

We define Open Long-Tailed Recognition (OLTR) as learning from such naturally distributed data and optimizing the classification accuracy over a balanced test set which include head, tail, and open classes.

Adversarial Motorial Prototype Framework for Open Set Recognition

Xiaziheng89/Adversarial-Motorial-Prototype-Framework-for-Open-Set-Recognition 13 Jul 2021

Second, this paper proposes the adversarial motorial prototype framework (AMPF) based on the MPF.

Evidential Deep Learning for Open Set Action Recognition

Cogito2012/DEAR ICCV 2021

Different from image data, video actions are more challenging to be recognized in an open-set setting due to the uncertain temporal dynamics and static bias of human actions.

Open-Set Recognition: a Good Closed-Set Classifier is All You Need?

sgvaze/osr_closed_set_all_you_need ICLR 2022

In this paper, we first demonstrate that the ability of a classifier to make the 'none-of-above' decision is highly correlated with its accuracy on the closed-set classes.
