Abstract: A method, a device, and a medium for managing a machine learning model based on distillation are provided. A first machine learning model is determined using a first reference sample associated with a first reference object in an application, the first reference sample including a first reference classification specified by a first reference object for a first reference media item. A prediction of a second reference classification by a second reference object in the application for the second reference media item is determined using the first machine learning model. A second reference sample is generated based on the second reference object, the second reference media item, and the prediction of the second reference classification. A second machine learning model is determined using the second reference sample, the second machine learning model describing an association between an object in the application and a classification by the object for the media item.

Abstract: A method, a device, and a medium for managing a machine learning model are provided. A prediction of a submission event between an object and a media item provided in the application is determined using a first machine learning model, the prediction of the submission event representing a probability that the object submits a response for a question associated with the media item. Based on the prediction of the submission event, a correction weight associated with the object is determined. A reference media item and a reference question associated with the reference media item are provided to the object in the application. In response to receiving a reference response submitted by the object for the reference question, the second machine learning model is updated based on the reference response and the correction weight, the second machine learning model describing an association relationship between the object and the reference media item.

Abstract: A water dispenser having beverage-making function is provided. The water dispenser can include a body defining a beverage making cavity with an open side therein; a beverage making assembly disposed in the beverage making cavity and including a beverage container for accommodating a beverage capsule, the beverage container having a first penetration member for penetrating a bottom of the beverage capsule; and a water injection mechanism for supplying water to the beverage capsule and having a second penetration member for penetrating a top of the beverage capsule.
