ChinaData

China_MultChange.mat (input data)

X_3d：channel, height, width
Y_3d：channel, height, width
endmember：channel, num_em
Two_CMap：height, width （0 means unchanged, 1 means changed） Mul_CMap：height, width （0 means unchanged, 1,2,3... means different changed class）

China_sampIdx_16384.mat (used for pre-training of United Unmixing Module.)

idx_sample： 1, 16384 （used for python index； selected for pre-training of United Unmixing Module）

China_sampIdx_12288_4096.mat (for pre-training of Temporal Correlation Module and alternative optimization of the two modules. )

binary_label, 1,12288（the first 8192 samples are unchanged（labeled value as 0）; the remained 4096 samples are changed, labeled value as 1）
idx_sample: 1, 12288（index of the samples, used for python index； selected for pre-training of Temporal Correlation Module and alternative optimization of the two modules ）
