Splet31. jan. 2024 · 2D PCA-plot showing clustering of “Benign” and “Malignant” tumors across 30 features. What we’re seeing here is a “clear” separation between the two categories of ‘Malignant’ and ‘Benign’ on a plot of just ~63% of variance in a 30 dimensional dataset. Simply using the two dimension in the plot above we could probably get some pretty …
