Visualization of feature matrix: acute lymphoblastic leukemia (ALL) vs. myeloid leukemia (AML). An ALL sample or feature vector x ∈ ℝd is transformed to feature matrix X ∈ ℝm × m using the procedure outlined in Table 1. These feature matrices are shown at top right side of the figure. Similarly, a sample of AML is also transformed to feature matrix and shown at bottom right side of the figure
