Exploring the Limits of Deep Image Clustering using Pretrained Models

1 code implementation31 Mar 2023 Nikolas Adaloglou, Felix Michels, Hamza Kalisch, Markus Kollmann

We present a general methodology that learns to classify images without labels by leveraging pretrained feature extractors.

Adapting Contrastive Language-Image Pretrained (CLIP) Models for Out-of-Distribution Detection

1 code implementation10 Mar 2023 Nikolas Adaloglou, Felix Michels, Tim Kaiser, Markus Kollmann

Intriguingly, we show that (i) PLP outperforms the previous state-of-the-art \citep{ming2022mcm} on all $5$ large-scale benchmarks based on ImageNet, specifically by an average AUROC gain of 3. 4\% using the largest CLIP model (ViT-G), (ii) we show that linear probing outperforms fine-tuning by large margins for CLIP architectures (i. e.

Self-Supervised Anomaly Detection by Self-Distillation and Negative Sampling

1 code implementation17 Jan 2022 Nima Rafiee, Rahil Gholamipoorfard, Nikolas Adaloglou, Simon Jaxy, Julius Ramakers, Markus Kollmann

Detecting whether examples belong to a given in-distribution or are Out-Of-Distribution (OOD) requires identifying features specific to the in-distribution.

We do hope that this series will provide you a big overview of the field, so that you will not need to read all the literature by yourself, independent of your background on GANs.
