Abstract: A method for discovering causality from data includes acquiring to-be-processed data, and obtaining a covariance matrix of the to-be-processed data; determining a first target column in the covariance matrix, taking the number of columns of the first target column as a first place in a rearrangement sequence, and obtaining a first upper triangular matrix according to the first target column; determining a position of the number of columns of the covariance matrix other than the first target column except the first place in the rearrangement sequence according to the first target column and the first upper triangular matrix, and obtaining an upper triangular matrix in each position determination; obtaining an adjacency matrix according to an upper triangular matrix and a rearrangement sequence obtained in final position determination; and generating directed acyclic graph (DAG) by using the adjacency matrix, and taking the DAG as causality discovery result of the to-be-processed data.

Abstract: The present application discloses a wakeup indicator monitoring method, apparatus and electronic device. The present disclosure includes: acquiring M pieces of audio data of a device to be monitored; determining a first wakeup confidence of each piece of M pieces of audio data, wherein the first wakeup confidence indicates a probability that the audio data contains a first wakeup word for waking up the device to be monitored; acquiring a first audio data with a first wakeup confidence in a target zone in M pieces of audio data, wherein the wakeup confidence in the target zone indicates that the audio data contains a wakeup word for waking up an audio device; and determining the ratio of the first audio data to M pieces of audio data as a wakeup rate of a device to be monitored, where the wakeup indicator of the device to be monitored includes the wakeup rate.

Abstract: Provided are a method and an apparatus for component fault detection based on an image, and a specific implementation is: when it is determined that an image shot by an image pickup apparatus for a component to be tested with a first shooting parameter does not meet a preset condition, adjusting the first shooting parameter to a second shooting parameter; controlling the image pickup apparatus to shoot for the component to be tested with the second shooting parameter to obtain a first image that meets the preset condition; and performing fault detection on the component to be tested according to the first image. The image pickup apparatus can be adjusted in real time, so that the image can be used for fault detection only when meeting the preset condition, thereby the image is kept stable, and the accuracy rate of component fault identification based on an image is improved.
