Evaluating Data Augmentation Techniques for Coffee Leaf Disease Classification

no code implementations11 Jan 2024 Adrian Gheorghiu, Iulian-Marius Tăiatu, Dumitru-Clementin Cercel, Iuliana Marin, Florin Pop

As the RoCoLe dataset is imbalanced and does not have many samples, fine-tuning of pre-trained models and multiple augmentation techniques need to be used.

Explainability-Driven Leaf Disease Classification Using Adversarial Training and Knowledge Distillation

no code implementations30 Dec 2023 Sebastian-Vasile Echim, Iulian-Marius Tăiatu, Dumitru-Clementin Cercel, Florin Pop

Through our experiments, we determine that on a benchmark dataset, the robustness can be the price of the classification accuracy with performance reductions of 3%-20% for regular tests and gains of 50%-70% for adversarial attack tests.

SkinDistilViT: Lightweight Vision Transformer for Skin Lesion Classification

1 code implementation16 Aug 2023 Vlad-Constantin Lungu-Stan, Dumitru-Clementin Cercel, Florin Pop

By adding classification heads at each level of the transformer and employing a cascading distillation process, we improve the balanced multi-class accuracy of the base model by 2. 1%, while creating a range of models of various sizes but comparable performance.
