Firstly, the variable data is effectively fitted using orthogonal non-negative matrix tri-factorization, and the missing data in the matrix is solved to construct a complete production condition relationship. Next, the support vector machine model and the deep residual contraction network model are trained in parallel to pre-diagnose process faults by mining linear and non-linear interaction features. Finally, a novel mapping relationship is established between the result and model levels using the multi-layer perceptron algorithm to complete the final diagnosis and evaluation of the fault.
