Abstract: Deep neural network (DNN) has been used for various applications to provide inference, regression, classification, and prediction. Although a high potential of DNN has been successfully demonstrated in literature, most DNN requires high computational complexity and high power operation for real-time processing due to a large number of multiply-accumulate (MAC) operations. The present invention provides a way to realize hardware-friendly MAC-less DNN framework with round-accumulate (RAC) operation operations based on power-of-two (PoT) weights. The method and system are based on the realization that rounding-aware training for powers-of-two expansion can eliminate the need of multiplier components from the system without causing any performance loss. In addition, the method and system provide a way to reduce the number of PoT weights based on a knowledge distillation using a progressive compression of an over-parameterized DNN.

Abstract: Connected and automated vehicles (CAVs) have shown the potential to improve safety, increase road throughput, and optimize energy efficiency and emissions in several complicated traffic scenarios. This invention describes a mixed-integer programming (MIP) optimization method for global multi-vehicle decision making and motion planning of CAVs in a highly dynamic environment that consists of multiple human-driven, i.e., conventional or manual, vehicles and multiple conflict zones, such as merging points and intersections. The proposed approach ensures safety, high throughput and energy efficiency by solving a global multi-vehicle constrained optimization problem. The solution provides a feasible and optimal time schedule through road segments and conflict zones for the automated vehicles, by using information from the position, velocity, and destination of the manual vehicles, which cannot be directly controlled.
