Abstract: Methods and systems are presented for classifying an item by dynamically probing different consumers for information related to the item. A description of the item may be parsed to identify a set of questions related to the item for probing consumers for additional information related to the item. The set of questions may be stored in a random forest associated with the item. The random forest may be traversed to select one or more subset of questions for probing a consumer for additional information. Once answers are obtained from a consumer based on the probing, the answers may be compiled with other answers stored in the random forest obtained from other consumers. The compiled answers may be used to generate an item classification for the item and may also be used to modify the random forest.

Abstract: The systems and methods disclosed herein provide determination of an orientation of a feature towards a reference target. As a non-limiting example, a system consistent with the present disclosure may include a processor, a memory, and a single camera affixed to the ceiling of a room occupied by a person. The system may analyze images from the camera to identify any objects in the room and their locations. Once the system has identified an object and its location, the system may prompt the person to look directly at the object. The camera may then record an image of the user looking at the object. The processor may analyze the image to determine the location of the user's head and, combined with the known location of the object and the known location of the camera, determine the direction that the user is facing. This direction may be treated as a reference value, or “ground truth.” The captured image may be associated with the direction, and the combination may be used as training input into an application.

Abstract: Techniques are disclosed relating to determining a predicted time interval for querying a database beginning at a starting point in time to retrieve a specified number of records. A computer system receives a request for records from a database that stores timestamped records, where the request is for a specified number of records beginning at a starting point in time. The computer system then determines a predicted time interval for querying the database beginning at the starting point in time to retrieve the specified number of records, where the predicted time interval may be determined by a machine learning module that is trained using historical database transaction data. Such techniques may advantageously improve the efficiency of individual queries in fetching a desired amount of data from a database for applications.
