Lightning Fast Video Anomaly Detection via Adversarial Knowledge Distillation

no code implementations28 Nov 2022 Nicolae-Catalin Ristea, Florinel-Alin Croitoru, Dana Dascalescu, Radu Tudor Ionescu, Fahad Shahbaz Khan, Mubarak Shah

We propose a very fast frame-level model for anomaly detection in video, which learns to detect anomalies by distilling knowledge from multiple highly accurate object-level teacher models.

LeRaC: Learning Rate Curriculum

no code implementations18 May 2022 Florinel-Alin Croitoru, Nicolae-Catalin Ristea, Radu Tudor Ionescu, Nicu Sebe

In this work, we propose a novel curriculum learning approach termed Learning Rate Curriculum (LeRaC), which leverages the use of a different learning rate for each layer of a neural network to create a data-free curriculum during the initial training epochs.

Discriminability-enforcing loss to improve representation learning

no code implementations14 Feb 2022 Florinel-Alin Croitoru, Diana-Nicoleta Grigore, Radu Tudor Ionescu

During the training process, deep neural networks implicitly learn to represent the input data samples through a hierarchy of features, where the size of the hierarchy is determined by the number of layers.
