UNIFIED OPTIMIZATION FOR CONVOLUTIONAL NEURAL NETWORK MODEL INFERENCE ON INTEGRATED GRAPHICS PROCESSING UNITS

Techniques for optimizing and deploying convolutional neural network (CNN) machine learning models for inference using integrated graphics processing units are described. A model compilation system optimizes CNN models using optimized vision-specific operators as well as both graph-level tuning and tensor-level tuning to explore the optimization space for achieving heightened performance. The model compilation system may also implement a heuristic-based two-stage technique for falling back certain operators of CNN models to use CPUs when needed or otherwise beneficial.
