Hyperbolic Space with Hierarchical Margin Boosts Fine-Grained Learning from Coarse Labels

NeurIPS 2023poster

Learning fine-grained embeddings from coarse labels is a challenging task due to limited label granularity supervision, i.e., lacking the detailed distinctions required for fine-grained tasks. The task becomes even more demanding when attempting few-shot fine-grained recognition, which holds practic…

An Embarrassingly Simple Approach to Semi-Supervised Few-Shot Learning

NeurIPS 2022accept

Semi-supervised few-shot learning consists in training a classifier to adapt to new tasks with limited labeled data and a fixed quantity of unlabeled data. Many sophisticated methods have been developed to address the challenges this problem comprises. In this paper, we propose a simple but quite ef…

Automatic Check-Out via Prototype-Based Classifier Learning from Single-Product Exemplars

ECCV 2022poster

"Automatic Check-Out (ACO) aims to accurately predict the presence and count of each category of products in check-out images, where a major challenge is the significant domain gap between training data (single-product exemplars) and test data (check-out images). To mitigate the gap, we propose a me…

Dual Attention Networks for Few-Shot Fine-Grained Recognition

AAAI 2022technical

The task of few-shot fine-grained recognition is to classify images belonging to subordinate categories merely depending on few examples. Due to the fine-grained nature, it is desirable to capture subtle but discriminative part-level patterns from limited training data, which makes it a challenging…
