 ![Displays of a typical $W$ jet (left) and a typical light quark jet (right) in $\Delta\eta$-$\Delta\phi$ plane. The charged tracks of jet particles are shown as circles with charge signs, while the neutral clusters are shown as squares. The sizes of the circles or the squares are proportional to the $p_T$'s of jet constituents. The solid lines indicate the top-one ranked 0PCs of the filters in the energy flow 0PCNN model. The strength of filter outputs are represented by the line thickness.[]{data-label="fig:jet_disp"}](pub_disp_
