A device and method for detecting wire breakage are provided. The wire breakage detection device includes an excitation coil, a detection coil, and a processor. The detection signal input end of the processor is connected to the detection coil. The excitation coil and the detection coil are located on two sides of a longitudinal section of an inner wall of a to-be-detected pipeline respectively, wherein a conductive closed structure is formed continuously and annularly in the to-be-detected pipeline, the axis of the excitation coil is parallel to the axis of the to-be-detected pipeline, and the axis of the detection coil is perpendicular to the axis of the to-be-detected pipeline. The excitation coil is configured to generate an alternating magnetic field according to an alternating electromagnetic signal, wherein an induced current and an electromagnetic field of the induced current are generated by the to-be-detected pipeline located in the alternating magnetic field.

A method receives user behavior information at a first system. The user behavior information is determined by user interaction with a first list sent to the user by a first network on a video delivery service. A first state is generated using the received user behavior information and prior user behavior information by the user from cells that store the prior user behavior. The method inputs the first state into a second network with the first recommendation list to generate a value that evaluates a performance of recommending the first recommendation list. An update to parameters is generated for the first network and provided to the first network. The first network generates a second state from the received user behavior information and prior user behavior information derived from cells that store the prior user behavior and outputs a second recommendation list using the second state and updated parameters.

Reinforcement learning network for recommendation system in video delivery system

In one embodiment, a method receives a video and information for entities that appear in the video. The video is played in a media player without displaying a queue configured to display one or more entities. When an input is received to display the queue while playing the video, the method performs: determining a set of entities in relation to a time associated with playing the video using the information for the entities that appear in the video and displaying the set of entities in the queue, wherein the video continues to play in the media player while the queue is displayed.

Queue to display information for entities during video playback

A method receives a candidate set of recommendations for video entities on a video delivery service in response to receiving a request to generate a page of an interface. A number for each recommendation is generated that represents a relevance rating of the respective recommendation minus a similarity rating between the respective recommendation and recommendations from the candidate set of recommendations that are added to a subset of recommendations. A recommendation is added to the subset of recommendations that has a maximum probability of being relevant to the user and diverse from the recommendations in the subset of recommendations based on the number. The method then updates the number for recommendations in the candidate set of recommendations based on adding the recommendation to the subset of recommendations. This process is iteratively performed and the subset of recommendations in the page of the interface is provided to a client device.

In one embodiment, a method receives a video for a media program and a set of captions for a dialog in the video. A media player plays the video. A time associated with playing of the video is determined and then the method determines a set of entities in relation to the time. The set of entities are included in one or more captions in the set of captions. The method displays the set of entities in a queue where the set of entities are associated with additional information for each respective entity in the set of entities.

In one embodiment, a method defines information for a set of genomes where the set of genomes describe characteristics of media programs. The method also defines which genomes in the set of genomes correspond to which topics in a set of topics. Textual information for a plurality of media programs and the information are input into a model and the model is trained to determine a probability distribution of terms for the set of topics based on analyzing the textual information and the genome information. The method then outputs the trained model. The probability distribution of terms is usable to determine genomes for each of the plurality of media programs where a genome corresponds to a topic and is associated with a media program based on terms found in the textual information for the media program and the probability distribution of terms for the topic correspond to the genome.

Topic model based media program genome generation

In one embodiment, a method determines a first local binary pattern for a first image in a video and a second local binary pattern for a second image in the video. Then, the method determines an optical flow between the first image and the second image based on a distance between the first local binary pattern and the second local binary pattern. The optical flow is output for use in aligning the first image to the second image.
