Two-dimensional t-SNE projections based on Stokes-V profiles observed on 29 May (two left panels) and on 6 June (two right panels). The five clusters identified in the t-SNE projections for both days are color-coded. The vertical magnetic field strength (second and fourth panels) is used to color the projections providing a visual guide to interpret the t-SNE projections. The back projections highlighting the onion-peel structure for both pores are shown at the top of the color-coded t-SNE projection.
