    摘要: The present invention is a method and system for automating the process for valuing a property that produces an estimated value of a subject property, and a quality assessment of the estimated value, that is based on the fusion of multiple processes for valuing a property. In one embodiment, three processes for valuing a subject property are fused. The first process, called LOCVAL, uses the location and living area to provide an estimate of the subject property's value. The second process, called AIGEN, is a generative artificial intelligence method that trains a fuzzy-neural network using a subset of cases from a case-base, and produces a run-time system to provide an estimate of the subject property's value. The third process, called AICOMP, uses a case based reasoning process similar to the sales comparison approach to determine an estimate of the subject property's value.

    摘要: A system and method for predicting web breaks in a paper machine. Principal components analysis (PCA) and classification and regression tree (CART) modeling are used to predict web break sensitivity from measurements taken from the paper mill. Also, the CART model is used to isolate the root cause of the predicted web break sensitivity.

    摘要: A system and method for providing raw mix proportioning control in a cement plant with a gradient-based predictive controller. A raw mix proportioning controller determines the correct mix and composition of raw materials to be transported to a mixer. The raw mix proportioning controller uses a gradient-based predictive controller to determine the proper mix and composition of raw materials. The gradient-based predictive controller takes targeted set points and the chemical composition of the raw material as inputs and generates the proportions of the raw material to be provided as an output for the next time step. The output is generated by using a non-linear constrained optimization.

    摘要: A computer-implemented method for validating specified prices on real property. A set of real estate properties comparable to the subject property are retrieved. A measurement of similarity between each comparable property and the subject property is then determined. A plurality of adjustment rules are then applied to adjust the price of the comparable properties. The adjusted comparable properties are then extracted, sorted, and ranked, according to the specified sale price. The extracted comparable properties are then aggregated into an estimate price of the subject property. After aggregation, the estimate price of the subject property is compared to the specified price and a measurement of confidence validating the reliability of the specified price is then generated.

    摘要: A fuzzy logic supervisory control architecture for aircraft engines includes a series of fuzzy proportional integral controllers each designed for a specific operating range and a fuzzy logic hierarchical controller for combining the fuel flow derivative outputs of the individual controllers. The hierarchical controller utilizes fuzzy logic on the input space fuzzified to linguistic values for engine temperature, power turbine speed and spool acceleration to determine a weighting to be given to each of the controller outputs for fuel flow derivative.
