Dataset and MATLAB Code for Identification of Equivalent GBM Meso-parameters Using GA-BP and Crack Fractal Dimension

This record contains the dataset, MATLAB scripts, fixed random seeds, data partitions, model-evaluation summaries, and supplementary materials supporting the article “Identification of Equivalent GBM Meso-parameters Using GA-BP and Crack Fractal Dimension.” GA-BP.zip contains the 300-record PFC database, fixed five-run training/validation/test partitions, GA-BP and conventional BP training scripts, configuration files, random seeds, and model-evaluation summaries. supplementary.zip contains the variable statistics, five-run SampleID ledger, nested training-subset SampleIDs, learning-curve summary, supplementary figures, and Supplementary Tables S4–S6. The database comprises 300 records. Model evaluation was performed using five fixed randomized 180/60/60 training/validation/test partitions.
