A visual tool revealing the TME subtypes integrated with targetable genomic alterations provides a planetary view of each tumor that can aid in oncology clinical decision making. The actual predictions of each node’s class/subject needs to be computed from this vector. To reduce the dimensionality, t-SNE generates a lower number of features (typically two) that preserves the relationship between samples as good as possible. The validity of the DE genes was evidenced by a clear separation of control and AD iNs by t-distributed stochastic neighbor embedding (tSNE) that largely confirmed the presence of an AD-specific transcriptome signature that unified most patient iN samples, despite some heterogeneity driven by four outlier samples (Figure 2C). Performing Mann-Whitney U test, we can conclude that UMAP preserves pairwise Euclidean distances significantly better than tSNE (p-value = 0.001) .
