"Mango dataset"

" All spectra of two seasons are shown in Figure (a). The average spectra of the two batches are shown in Figure (b). The main difference comes from the 400-700 nm, these differences may be due to the different contents of anthocyanins, chlorophyll, and other substances in samples from different seasons. There is a slight difference in the 700-1150 nm. The absorbance of season 1 is higher than that of season 2 near 980 nm. If the source domain calibration model is used directly to predict the target domain spectra, significant errors will occur."

两季的全部光谱均展示于图(a)中。两个批次的平均光谱则展示于图(b)中。主要差异集中于400~700 nm波段区间，该差异可能源于不同季节的样品中花青素、叶绿素及其他物质的含量差异。700~1150 nm波段仅存在细微差异。在980 nm附近，第1季的吸光度高于第2季。若直接使用源域校准模型对目标域光谱进行预测，则会产生显著误差。
