  • Publication number: 20260051167
    Abstract: A method includes obtaining plant-related information associated with a growing area, where the plant-related information includes information identifying multiple weeds detected within the growing area. The method also includes processing at least some of the plant-related information to estimate at least one location at risk of weed germination in the growing area. Processing at least some of the plant-related information includes estimating the at least one location at risk of weed germination based at least partially on locations where the identified weeds were detected within the growing area. Estimating the at least one location at risk of weed germination may include performing clustering based on the locations where the identified weeds were detected within the growing area, such as by performing the clustering using a machine learning clustering algorithm.

  • Publication number: 20250156599
    Abstract: A method includes obtaining, using at least one processing device (202, 314) of an electronic device (102a-102d, 106, 200, 300), spatial information (500, 600, 800, 900, 1100, 1200) associated with weeds in a growing area. The spatial information includes spatial information (500, 800, 1100) associated with a primary weed in the growing area over time. The method also includes identifying, using the at least one processing device, one or more portions of the growing area in which the primary weed has developed or may be developing herbicide resistance using the spatial information. In addition, the method includes outputting, using the at least one processing device, information (700, 1000, 1300) associated with the one or more identified portions of the growing area.

  • Publication number: 20230215511
    Abstract: An apparatus includes at least one processor configured to obtain multiple spatiotemporal population projection models. Different spatiotemporal population projection models are associated with different pests, diseases, or biocontrol agents. Each spatiotemporal population projection model defines how the associated pest, disease, or biocontrol agent spreads and contracts in a growing area over time. The at least one processor is also configured to receive information associated with an actual presence of a specific pest, disease, or biocontrol agent at one or more monitored spatial locations in the growing area. Different monitored spatial locations in the growing area are associated with different plants. The at least one processor is further configured to project a future presence of the specific pest, disease, or biocontrol agent in the growing area using the spatiotemporal population projection model associated with the specific pest, disease, or biocontrol agent.

  • Patent number: 11307562
    Abstract: A method and system for reinforcement learning can involve applying a finite-difference approach to a controller, and tuning the controller in response to applying the finite-difference approach by taking a state as an entirety of a closed-loop step response. The disclosed finite-different approach is based on a random search to tuning the controller, which operates on the entire closed-loop step-response of the system and iteratively improves the gains towards a desired closed-loop response. This allows for prescribing stability requirement into the reward function without any modeling procedures.
