Do ImageNet-trained Models Learn Shortcuts? The Impact of Frequency Shortcuts on Generalization

CVPR 2025poster

Frequency shortcuts refer to specific frequency patterns that models heavily rely on for correct classification. Previous studies have shown that models trained on small image datasets often exploit such shortcuts, potentially impairing their generalization performance. However, existing methods fo…

Dynamic Sparse Training versus Dense Training: The Unexpected Winner in Image Corruption Robustness

ICLR 2025poster

It is generally perceived that Dynamic Sparse Training opens the door to a new era of scalability and efficiency for artificial neural networks at, perhaps, some costs in accuracy performance for the classification task. At the same time, Dense Training is widely accepted as being the "de facto" app…

Not Only Text: Exploring Compositionality of Visual Representations in Vision-Language Models

CVPR 2025highlight

Vision-Language Models (VLMs) learn a shared feature space for text and images, enabling the comparison of inputs of different modalities. While prior works demonstrated that VLMs organize natural language representations into regular structures encoding composite meanings, it remains unclear if com…

Fourier-basis Functions to Bridge Augmentation Gap: Rethinking Frequency Augmentation in Image Classification

CVPR 2024poster

Computer vision models normally witness degraded performance when deployed in real-world scenarios due to unexpected changes in inputs that were not accounted for during training. Data augmentation is commonly used to address this issue as it aims to increase data variety and reduce the distribution…

Regressing Transformers for Data-efficient Visual Place Recognition

ICRA 2024poster

Visual place recognition is a critical task in computer vision, especially for localization and navigation systems. Existing methods often rely on contrastive learning: image descriptors are trained to have small distance for similar images and larger distance for dissimilar ones in a latent space.…

Data-Efficient Large Scale Place Recognition With Graded Similarity Supervision

CVPR 2023poster

Visual place recognition (VPR) is a fundamental task of computer vision for visual localization. Existing methods are trained using image pairs that either depict the same place or not. Such a binary indication does not consider continuous relations of similarity between images of the same place tak…

What do neural networks learn in image classification? A frequency shortcut perspective

ICCV 2023poster

Frequency analysis is useful for understanding the mechanisms of representation learning in neural networks (NNs). Most research in this area focuses on the learning dynamics of NNs for regression tasks, while little for classification. This study empirically investigates the latter and expands the…
