The zero-shot sketch-based image retrieval (\\underline{ZS-SBIR}) is more generic and practical but poses an even greater challenge because of the additional knowledge gap between the seen and unseen categories. To simultaneously mitigate both gaps, we propose an \\textbf{A}pproaching-and-\\textbf{C}entralizing \\textbf{Net}work (termed \"\\textbf{ACNet}\") to jointly optimize sketch-to-photo synthesis and the image retrieval.
