C3: Cross-instance guided Contrastive Clustering

1 code implementation14 Nov 2022 Mohammadreza Sadeghi, Hadi Hojjati, Narges Armanfard

In this paper, we propose a novel contrastive clustering method, Cross-instance guided Contrastive Clustering (C3), that considers the cross-sample relationships to increase the number of positive pairs and mitigate the impact of false negative, noise, and anomaly sample on the learned representation of data.

DASVDD: Deep Autoencoding Support Vector Data Descriptor for Anomaly Detection

1 code implementation9 Jun 2021 Hadi Hojjati, Narges Armanfard

In this paper, we propose a method, DASVDD, that jointly learns the parameters of an autoencoder while minimizing the volume of an enclosing hyper-sphere on its latent representation.
