Learning to Draw: Emergent Communication through Sketching Appendices

A How does the sketch complexity influence communication? 2 B How important is the rasteriser? 2 C What is the impact of L in the computation of the perceptual loss on the emergent sketches? A How does the sketch complexity influence communication? An interesting question one might ask about a model that learns to communicate by drawing is how complex the sketch image needs to be so that its meaning can be conveyed successfully and communication can be established. We attempt to answer this question by varying the number of lines that our model is allowed to draw to represent the input photograph. In Table I, we show results for experiments run with 5, 10 and 20 lines allowed for sketching.
