Contrastive and Variational Approaches in Self-Supervised Learning for Complex Data Mining
This work addresses feature extraction and classification challenges in complex data mining for applications in fields with unlabeled data, but it is incremental as it combines existing methods like contrastive learning and variational modules.
The paper tackled the problem of feature extraction and classification in complex, unlabeled data mining by proposing a self-supervised learning algorithm, which improved classification accuracy and demonstrated adaptability across different datasets while maintaining high detection accuracy under varying data distributions.
Complex data mining has wide application value in many fields, especially in the feature extraction and classification tasks of unlabeled data. This paper proposes an algorithm based on self-supervised learning and verifies its effectiveness through experiments. The study found that in terms of the selection of optimizer and learning rate, the combination of AdamW optimizer and 0.002 learning rate performed best in all evaluation indicators, indicating that the adaptive optimization method can improve the performance of the model in complex data mining tasks. In addition, the ablation experiment further analyzed the contribution of each module. The results show that contrastive learning, variational modules, and data augmentation strategies play a key role in the generalization ability and robustness of the model. Through the convergence curve analysis of the loss function, the experiment verifies that the method can converge stably during the training process and effectively avoid serious overfitting. Further experimental results show that the model has strong adaptability on different data sets, can effectively extract high-quality features from unlabeled data, and improves classification accuracy. At the same time, under different data distribution conditions, the method can still maintain high detection accuracy, proving its applicability in complex data environments. This study analyzed the role of self-supervised learning methods in complex data mining through systematic experiments and verified its advantages in improving feature extraction quality, optimizing classification performance, and enhancing model stability
