Researchers have developed a novel Bayesian framework to jointly model multi-sensor time-series data and failure event data for systems with multiple failure modes. This approach integrates a Cox proportional hazards model, a Convolved Multi-output Gaussian Process, and multinomial failure mode distributions to provide accurate predictions with robust uncertainty quantification. The model's effectiveness was demonstrated through extensive numerical studies and a case study using jet-engine data. AI
