+The PyTorch implementation code of the paper, [Cross-to-merge training with class balance strategy for learning with noisy labels](https://doi.org/10.1016/j.eswa.2024.123846).
+
+**Abstract**
+The collection of large-scale datasets inevitably introduces noisy labels, leading to a substantial degradation in the performance of deep neural networks (DNNs). Although sample selection is a mainstream method in the field of learning with noisy labels, which aims to mitigate the impact of noisy labels during model training, the testing performance of these methods exhibits significant fluctuations across different noise rates and types. In this paper, we propose Cross-to-Merge Training (**C2MT** ), a novel framework that is insensitive to the prior information in sample selection progress, enhancing model robustness. In practical implementation, using cross-divided training data, two different networks are cross-trained with the co-teaching strategy for several local rounds, subsequently merged into a unified model by performing federated averages on the parameters of two models periodically. Additionally, we introduce a new class balance strategy, named Median Balance Strategy (MBS), during the cross-dividing process, which evenly divides the training data into a labeled subset and an unlabeled subset based on the estimated loss distribution characteristics. Extensive experimental results on both synthetic and real-world datasets demonstrate the effectiveness of C2MT. The Code will be available at: https://github.com/LanXiaoPang613/C2MT

+```shell
+python train_cifar_c2mt.py --r 0.2 --lambda_u 0
+python train.py --r 0.4 --noise_mode 'asym' --lambda_u 10 --data_path './data/cifar-10-batches-py' --dataset 'cifar10' --num_class 10
+python train.py --r 0.5 --noise_mode 'sym' --lambda_u 25 --data_path './data/cifar-10-batches-py' --dataset 'cifar10' --num_class 10
+```
+
+To train on the Animal-10N dataset, run the following command:
+
+```shell
+python train.py --num_epochs 60 --lambda_u 0 --data_path './data/Animal-10N' --dataset 'animal10N' --num_class 10
+```
