a, b denote the activation maps produced by the MultiChannel_2.5D_DL model, specifically for gliomas characterized as Non-IDH wild-type with TERTp-mut. Conversely, c, d represent the activation maps of features identified and emphasized by the same MultiChannel_2.5D_DL model, but this time for gliomas exhibiting IDH wild-type (wt) with TERT promoter mutation (TERTp-mut).
