Recently, the Cooperative Training Algorithm (CTA), a well-known Semi-Supervised Learning (SSL) technique, has garnered significant attention in the field of image classification. However, traditional CTA approaches face challenges such as high computational complexity and low classification accuracy. To overcome these limitations, we present a novel approach called Weighted fusion based Cooperative Training Algorithm (W-CTA), which leverages the cooperative training technique and unlabeled data to enhance classification performance. Moreover, we introduce the K-means Cooperative Training Algorithm (Km-CTA) to prevent the occurrence of local optima during the training phase. Finally, we conduct various experiments to verify the performance of the proposed methods. Experimental results show that W-CTA and Km-CTA are effective and efficient on CIFAR-10 dataset.
