Abstract—In this paper, we propose a multi-input attentionbased deep-learning architecture for machine fault diagnosis, which is a challenging task due to environmental noises and signal interference that are inevitable in practical industry environments. Specifically, we develop an attention mechanism to focus on the most effective signal characteristics and achieve highly accurate fault classifications under various working conditions. First, we construct multi-dimensional features to characterize both time-domain and frequency-domain properties of machine vibration signals. Afterwards, we design a novel multi-input multi-branch (MIMB) architecture incorporating multiple sub-networks to enhance the learning of discriminant capabilities. The derived features from each subnetwork are fused to form an input to the final classification layer. To verify the effectiveness of the proposed approach, we conduct comprehensive experiments on the bearing database of Universität Paderborn, Germany, which is generally recognized as the benchmark to compare the performance of various algorithms. Numerical results show that the proposed approach achieves the state-of-the-art classification accuracy and has a noticeable performance gain over the previous schemes in the literature.
