 which computes the lrp heatmaps according to the `epsilon_gamma_box` rule and stores them in `results`, along with the respective input images.
+Other possible composites that can be passed to `--composites` are, e.g., `epsilon_plus`, `epsilon_alpha2_beta1_flat`, `guided_backprop`, `excitation_backprop`.
 
 The resulting heatmaps may look like the following:
