Figure 9. Coupled matrix and tensor factorization on in vitro breast samples represented by tensor.

Figure 9

Inline graphic and histology samples represented by matrix Y ( Figure 2 ). (a) The 1st column of matrix B corresponding to the in vitro samples mode extracted by a CMTF model can separate cancer (blue-square sign) from normal (light blue-plus sign) tissue samples; (b) Unlike for brain and bone tissues, matrix D corresponding to the histology samples mode extracted using a CMTF model cannot separate cancer samples (red-triangle sign) from healthy (green-star sign) samples; (c) features captured by the common component extracted by CMTF. Cell-graph features identified as influential in the coupled analysis are similar to the features in Figure 5c and 7c with some minor differences.
