FT-MoE: Sustainable-learning Mixture of Experts Model for Fault-Tolerant Computing with Multiple Tasks
This addresses fault prediction and diagnosis for reliable service systems, but it appears incremental as it builds on existing deep learning approaches with a novel hybrid method.
The paper tackles the problem of fault-tolerant computing by proposing FT-MoE, a mixture-of-experts model that improves fault detection and classification performance, achieving superior results compared to state-of-the-art methods on a benchmark.
Intelligent fault-tolerant (FT) computing has recently demonstrated significant advantages of predicting and diagnosing faults in advance, enabling reliable service delivery. However, due to heterogeneity of fault knowledge and complex dependence relationships of time series log data, existing deep learning-based FT algorithms further improve detection performance relying on single neural network model with difficulty. To this end, we propose FT-MoE, a sustainable-learning mixture-of-experts model for fault-tolerant computing with multiple tasks, which enables different parameters learning distinct fault knowledge to achieve high-reliability for service system. Firstly, we use decoder-based transformer models to obtain fault prototype vectors of decoupling long-distance dependencies. Followed by, we present a dual mixture of experts networks for high-accurate prediction for both fault detection and classification tasks. Then, we design a two-stage optimization scheme of offline training and online tuning, which allows that in operation FT-MoE can also keep learning to adapt to dynamic service environments. Finally, to verify the effectiveness of FT-MoE, we conduct extensive experiments on the FT benchmark. Experimental results show that FT-MoE achieves superior performance compared to the state-of-the-art methods. Code will be available upon publication.
