fine-grained classification with noisy labels
Fine-grained classification with noisy labels is a challenging problem that aris frequently in many real-world applications such as image recognition, speech recognition, and natural language processing. Noisy labels refer to the imperfections or mistakes in the labelling of data by humans or automatic algorithms. Label noi can have a significant impact on the performance of supervid learning algorithms, leading to degraded accuracy and generalization.
The traditional approach to address the problem of noisy labels is to collect and annotate more data to improve the quality of the labels. Alternatively, one can u techniques such as data cleaning, outlier detection, or active learning to refine the labels. However, the approaches are often not practical or too expensive, especially in the context of fine-grained classification where the label space is large and the annotation process is time-consuming.

assification with noisy labels. One approach is to u deep neural networks (DNNs) that are specifically designed to handle noisy labels. DNNs have shown impressive performance on various machine learning tasks, including image recognition and speech recognition. However, DNNs are prone to overfitting if the training data is noisy, which can lead to poor generalization performance.
赵丽娇 To overcome the overfitting issue, many recent studies have propod novel methods that introduce noi-aware regularization techniques or label correction strategies during training. For example, some methods u a combination of hard and soft label assignments to generate more robust models that are less nsitive to label noi. Others u deep enmbles to average the predictions of multiple networks with different initializations and weight configurations, which can reduce the variability of the models caud by label noi.
Another approach is to incorporate domain knowledge or prior information into the model to improve its robustness to label noi. For instance, one can u knowledge abo
ut the structure or distribution of the data to constrain the model's predictions, which can improve its accuracy and generalization performance. Alternatively, one can leverage external sources of knowledge, such as pre-trained models or knowledge graphs, to help the model learn more meaningful and reliable features that are less affected by label noi.
