In order to solve the problem of over-fitting of traditional supervised learning methods in anomaly detection of unbalanced datasets, an unsupervised adversarial learning method is proposed for hard disk failure prediction. This method uses the long short-term memory neural network and fully connected layer to design an Autoencoder that can be used for secondary coding. Only normal samples are used for training. By reducing the reconstruction error and the distance between potential vectors, the model can learn the data distribution of normal samples, thus improving the generalization ability of the model. The model also introduces the generative adversarial network to enhance the effect of unsupervised learning. Experiments on several datasets show that the recall rate and precision of the proposed method are higher than those of traditional supervised learning and semi-supervised learning classifiers, and that its generalization ability is stronger. Therefore, the unsupervised adversarial learning method is effective in hard disk failure prediction.

Key words: anomaly detection, hard disk failure prediction, generative adversarial network, unsupervised learning
