Web25 de jun. de 2024 · Extensive experiments on three long-tailed classification datasets demonstrate the advantage of the proposed contrastive learning based hybrid networks in long-tailed classification. Published in: 2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) Article #: Date of Conference: 20-25 June 2024 WebAbstract. Existing long-tailed classification (LT) methods only focus on tackling the class-wise imbalance that head classes have more samples than tail classes, but overlook the attribute-wise imbalance. In fact, even if the class is balanced, samples within each class may still be long-tailed due to the varying attributes.

WebTherefore, long-tailed classification is the key to deep learning at scale. However, existing methods are mainly based on re-weighting/re-sampling heuristics that lack a fundamental theory. In this paper, we establish a causal inference framework, which not only unravels the whys of previous methods, but also derives a new principled solution. Web16 de set. de 2024 · This paper proposes a novel paradigm called ProCo, addressing the long-tailed classification problem in a contrastive way. Our ProCo mainly consists of three components: i) category prototype and the adversarial proto-instance; ii) prototype recalibration strategy and iii) a unified proto-loss. fit to path in illustratorWebExisting long-tail image classification methods try to alleviate the head-tail imbalance majorly by re-balancing the data distribution, assigning the optimized weights, and augmenting information, but they often get in trouble with the trade-off on the head and tail performance which mainly caused by the poor representation learning of tail classes. can i get nhs hearing aids

"Web17 de ago. de 2024 · The reason for the performance degradation mainly comes from two aspects: (1) The long-tailed distribution of data. The number of the instances from tail classes (, only 1 instance for one class) is insufficient for training a deep learning model, resulting in under-fitting of these classes.
