ALEXANDRIA, Va., June 16 -- United States Patent no. 12,306,166, issued on May 20, was assigned to Hong Kong Applied Science and Technology Research Institute Co. Ltd. (Hong Kong).

"Self-adaptive optimization framework for water quality prediction" was invented by Zheng Long Li (Hong Kong) and Laifa Fang (Shenzhen, China).

According to the abstract* released by the U.S. Patent & Trademark Office: "The framework predicts water-quality data from observation data associated with raw features, e.g., rainfall. In the framework, an artificial neural network (ANN) computes the predicted water-quality data from feature data associated with impact features and derived from the observation data. The impact features are learnable, and are selected f...
