    Abstract: A method and apparatus for controlling an unmanned device, a storage medium, and an electronic device are provided. In some embodiments, not only a control policy is determined according to a single frame of a current image, but a safety representation value of an unmanned device at a current moment and safety representation values of the unmanned device at respective historical moments are respectively determined according to a current image and environment images of several historical moments. In those embodiments, a control policy of the unmanned device at a next moment is determined according to a safety representation value of the unmanned device at current moment and the safety representation values of the unmanned device at respective historical moments.

    Abstract: An image retrieval method is provided. According to an example of the method, based on a first image feature of an image to be retrieved, a binary feature of the image to be retrieved may be determined, and an information entropy code of the image to be retrieved may be further determined based on the binary feature of the image to be retrieved. Then, based on the information entropy code of the image to be retrieved, images similar to the image to be retrieved may be retrieved in a preset image library.

    Abstract: A method of determining a geofence based on user locations belongs to the field of computer technologies. The method of determining a geofence based on user locations includes: obtaining user locations in a plurality of pieces of user data; aggregating the user locations according to similarities in latitude and longitude coordinates of the user locations, to determine aggregation points and a central aggregation point; denoising the aggregation points according to distances between the aggregation points and the central aggregation point; and sorting, according to values of longitude coordinates or latitude coordinates, aggregation points obtained after the denoising, to determine geofence boundary data in a preset format.
