Model-less Is The Best Model: Generating Pure Code Implementations to Replace On-device DL Models
A program analysis method that can extract the core computing codes of on-device DL models, configure the extracted codes, and produce an executable program. It can hide the DL component in the deployment environment, accelerate the model inference, and reducce memory consumptions.
