Ancient ceramic source breaking method based on matrix dimensionality reduction

The invention discloses an ancient ceramic source breaking method based on matrix dimensionality reduction. The method comprises the following steps: collecting chemical elements of ceramics in a first production place and ceramics in a second production place to form a data set; processing the data set to obtain an element set matrix, a basis matrix, a coding matrix, a processed first producing area element set and a processed second producing area element set; calculating the element set matrix, the basis matrix and the coding matrix to obtain an S-CU number set; respectively calculating the processed first producing area element set and the processed second producing area element set to obtain a dimensionality-reduced element data set and an M-CU number set of the first producing area; obtaining a similarity measurement value NACS number set based on the S-CU number set and the dimension-reduced element data set of the first producing area; and judging whether homology exists or not through the M-CU number
