Embodiment 1
[0095] where SHAP is an additivity explanatory model inspired by the Shapley value. Shapley value originated from
[0108] Before data analysis, all must be preprocessed. It should be noted that the production and processing data in the industrial manufacturing field,
[0110] (1) Delete and record the process parameters that are highly correlated with each other.
[0112] Therefore, the correlations among all process parameters were first calculated. For two process parameters whose correlation exceeds the preset value
[0114] Preferably, the present invention adopts the Pearson correlation coefficient to calculate the correlation of the numerical process parameters.
[0115] (2) Use multiple independent type selection variables to replace the original single type selection parameter.
[0124]
[0127]
[0146] The SHAP value reflects the direction in which the feature affects the model output ("enhancing the output" or "reducing the output") and the effect of
Embodiment 2
[0150] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.
[0153] In the traditional regression analysis method, the number of bad samples is large enough and the processing status of different processing equipment
[0154] The present invention is described below for the analysis of some unfavorable real data in the production of a certain type of glass panel.
[0157] The failure detection data of the glass panel records the product number of the glass panel, the type of failure, and the severity of the failure.
[0158] At the same time, in the original processing data of the product, only the processing records of the product that retains the quality inspection data are screened.
[0159] Obviously, in other embodiments, the product quality grades can be divided into other multiple grade categories, and can also be repeated
[0161] According to the product numb...
