Nettet1. feb. 2024 · TL;DR: A simple and effective method for combating the label noise via joint instance and label reweighting. Abstract: Deep neural networks are powerful tools for representation learning, but can easily overfit to noisy labels which are prevalent in many real-world scenarios. Generally, noisy supervision could stem from variation among … Nettet9. nov. 2024 · Constrained Instance and Class Reweighting for Robust Learning under Label Noise. Deep neural networks have shown impressive performance in supervised learning, enabled by their ability to fit well to the provided training data.

Nettet10. feb. 2024 · For instance-wise calibration, we present a novel prototype modification strategy to aggregate prototypes with intra-class and inter-class instance reweighting. For metric-wise calibration, we present a novel metric to implicitly scale the per-class prediction by fusing two spatial metrics respectively constructed by the two networks. Nettet28. jun. 2014 · Visual domain adaptation, which learns an accurate classifier for a new domain using labeled images from an old domain, has shown promising value in computer vision yet still been a challenging problem. Most prior works have explored two learning strategies independently for domain adaptation: feature matching and instance … Nettetfor 1 dag siden · There is a surge of interests in recent years to develop graph neural network (GNN) based learning methods for the NP-hard traveling salesman problem (TSP).
