CDLN(Conditional　Deep　Learning　Network)　is　a　structure　of　convolution　neural　network　with　multiple　classifiers.　CDLN　could　improve　the　speed　for　the　task　of　classification　while　the　module　of　the　network　is　still　too　large　for　mobile　devices.　To　address　this　issue,　a　method　for　compressing　CDLN,　which　is　named　one-shot　whole　network　compression　scheme.　In　the　experiments,　the　module　size　and　time　cost　are　significantly　reduced　while　the　accuracy　of　the　network　losses　a　little.
