Deploying facial recognition solutions in bank, security government or police station faces two bottlenecks: network bandwidth and computing capabilities, that negatively impact deep learning inference throughput and latency, thereby resulting in less than optimal user experiences.


For facial recognition, a customized Resnet50 (FP32 and INT8) model was optimized on Intel Caffe.  Compared to FP32, Intel® DL Boost (delivered by Vector Neural Network Instructions (VNNI)/INT8) optimizations helped achieve a speedup of 3.3X in inference latency, for the same batch size and same instance (see chart)123.  The application also meets Cloudwalk’s desired accuracy requirement (of accuracy loss being less than 0.03%).


Significantly reduced deep learning inference latency, delivering better user experience – Cloudwalk customers will benefit from improved performance (i.e., lower latency), while maintaining SLAs for accuracy loss.

Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors. Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer systems, components, software, operations, and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.
