Latest Patents

Haijun He holds a patent for a "Soft measurement method for dioxin emission concentration in municipal solid waste incineration process." This patent discloses a soft measurement method of dioxin emission concentration based on multi-source latent feature selective ensemble (SEN) modeling. The method involves dividing the municipal solid waste incineration (MSWI) process data into subsystems according to industrial processes. Principal component analysis (PCA) is utilized to extract latent features from these subsystems. The process includes evaluating the correlation between the selected latent features and dioxin emissions using mutual information (MI). Ultimately, a least squares-support vector machine (LS-SVM) algorithm is employed to establish sub-models for different subsystems, optimizing the selection of these models through advanced algorithms.
