Experimental dataset for ISSA-GRNN modeling of camphor extraction from Artemisia argyi

This dataset contains the 50 experimental runs used to train and evaluate the ISSA-GRNN model for camphor extraction from Artemisia argyi leaves, as reported in "A Novel ISSA-GRNN Approach for Efficient Camphor Extraction from Artemisia argyi" (submitted to Scientific Reports). Each row corresponds to one extraction run with five input parameters (pH, temperature, cellulase concentration, hydrolysis duration, ultrasonication time) and one output (camphor extraction yield, mg/g). The file camphor_dataset.csv lists all 50 records; README.txt explains variable names, units, and the section mapping to the manuscript (Section 2.3 sampling, Section 3.3.2 five-fold CV). The MATLAB code for ISSA-GRNN is not included here and is available from the corresponding author upon reasonable request.
