Latest Patents

Hao Hai Ma's latest patents include a "Method and system for adaptive cycle-level traffic signal control." This invention describes methods, systems, and processor-readable media for adaptive cycle-level traffic signal control. The adaptive cycle-level traffic signal controller operates within a continuous action space, employing a reinforcement learning algorithm known as Proximal Policy Optimization (PPO). This algorithm generates signal cycle phase durations selected from a continuous range of values, allowing for more dynamic traffic management. The controller's inputs reflect the current and past states of the traffic environment, and the average duration of vehicle delay is used to calculate rewards for the reinforcement learning model.

Another significant patent is related to "Resource scheduling methods using positive and negative caching, and a resource manager implementing the methods." This invention defines leaf buckets with coordinates in a corresponding coordinate space. Nodes with resource values are mapped onto these leaf buckets, and task requests identify candidate nodes and requested resources. The scanning process for finding suitable nodes is optimized using positive and negative cache entries, enhancing the efficiency of resource allocation.
