    Abstract: An antenna device and a beam direction adjustment method are provided. The antenna device includes an antenna element, a metal element, and a substrate. The antenna element and the metal element are separately disposed on the substrate at a preset distance. A ground point of the metal element is fastened on a pad of the substrate, and the ground point is on a side of the metal element close to the antenna element. A first reverse current opposite to an antenna current generated by the antenna element is obtained through coupling on the side of the metal element close to the antenna element, and a second reverse current opposite to a substrate current generated by the substrate is obtained through coupling at a lower part of the metal element that is in contact with the substrate.

    Abstract: A wearable device includes: a metal middle cover, a metal bottom cover, a printed circuit board PCB, and a gap. The metal middle cover encircles the wearable device for a whole circle and serves as an exterior of the wearable device. The metal bottom cover is located under the metal middle cover and serves as a rear cover of the wearable device. The gap with a preset width exists between the metal middle cover and the metal bottom cover, and serves as a slot antenna of the wearable device. The PCB is in an inner side of the metal middle cover, and is located above the metal bottom cover. The PCB is electrically connected to the metal middle cover by using a feed point, and feeds power to the metal middle cover.

    Abstract: In a recommendation-providing method in the field of artificial intelligence, an apparatus for generating recommendations obtains a recommendation system status parameter based on a plurality of historical recommended objects and a user behavior for each historical recommended object, such as clicks or downloads. The apparatus determines a target set among lower-level sets according to the recommendation system status parameter and a selection policy corresponding to an upper-level set, where the lower-level sets and upper-level set correspond to nodes on a clustering tree representing available to-be-presented objects, and each set corresponds to one selection policy. The apparatus then determines a target to-be-recommended object from the to-be recommended objects in the target set.

    Abstract: A recommendation model training method, a selection probability prediction method, and an apparatus are provided. The training method includes obtaining a training sample, where the training sample includes a sample user behavior log, position information of a sample recommended object, and a sample label. The training method further includes performing joint training on a position aware model and a recommendation model by the training sample, to obtain a trained recommendation model, where the position aware model predicts probabilities that a user pays attention to a target recommended object when the target recommended object is at different positions, and the recommendation model predicts, when the user pays attention to the target recommended object, a probability that the user selects the target recommended object.

    Abstract: An antenna of a wearable device includes a metal bottom housing of the wearable device, a printed circuit board, a metal middle housing that encircles the printed circuit board, and a communications circuit set on the printed circuit board. A slot exists between the metal middle housing and the metal bottom housing. The metal middle housing is connected to the metal bottom housing using a second connecting wire. The metal middle housing and the printed circuit board jointly serve as a ground plate. An antenna feed line is used to connect the metal bottom housing and the communications circuit module. The metal bottom housing serves as an antenna radiation body.
