The invention discloses a knowledge acquisition method and system based on causal inference, and belongs to the field of natural language processing. The method comprises the following steps: firstly, constructing a causal graph by identifying a causal dependency relationship between events in a text; secondly, inputting a process text containing missing steps and candidate steps, extracting events, judging whether a causal relationship exists or not through a causal graph, and taking related causal information as additional features; and respectively calculating probabilities that the candidate steps contain and do not contain the dominant entity, coding through the two models, and calculating probabilities that the candidate steps are used as missing steps in combination with a multi-layer perceptron. And finally, comparing the probabilities of all the candidate steps with a negative class threshold, and determining the candidate step which most accords with the condition or judging that the correct step does not exist. According to the method, the causal relationship between events is additionally introduced, so that the more accurate knowledge acquisition capability is realized.

The present invention relates to the field of target detection technology, and provides a label-based vehicle-mounted millimeter-wave radar multi-target detection method and system. The method includes: obtaining a multi-target predicted state set based on a multi-target state set prediction at a first moment; updating the weights of particles based on a measurement set obtained by detection of a vehicle-mounted millimeter-wave radar at a second moment; adjusting the labels of particles based on the updated weights; clustering particles in the multi-target predicted state set at the second moment based on the labels, and weighted averaging the clustering results based on the weights to obtain the multi-target detection results at the second moment. The present invention detects and identifies the states of multiple targets through a label-based particle filter, thereby avoiding unnecessary association of detection targets; at the same time, the technical means of updating weights through measurement and adjusting labels through weights can further enhance the accuracy of multi-target recognition results.

The present invention prevents an information processing element copied from a first device to a second device from being associated with a storage area in a second device that is associated with a user who is different from a user associated with a storage area in the first device. The present invention provides a device, an information processing apparatus, a recording medium, and a computer program product. A backup generation unit of a certain device generates backup data and sends it to a user. The backup data includes a designated one-click application, a number of a file box that is an output target of a processing result of the one-click application, and information about the owner of the file box. The user inputs the backup data to another device. If the owner of the file box in the device indicated by the number of the backup data is different from the person indicated by the owner information in the backup data, the application copying unit of the device will select the file box with the person indicated by the information in the device as the output target of the processing result of the one-click application as the file box.

The invention relates to an unmanned store customer tracking method and system, and the method specifically comprises the steps: shooting an unmanned store video through a camera of an unmanned store, carrying out the target detection of frames in the video, obtaining a detection frame, obtaining a track of a confirmation state which is matched unsuccessfully last time, carrying out the statistics of the number of times of matching failure of the track of the confirmation state which is matched unsuccessfully, and carrying out the tracking of the customer. Adjusting the weight of the mahalanobis distance and the appearance cosine distance of the track of the matching failure in the current cascade matching based on the number of times of the matching failure; if the track which fails to match fails in the current cascade matching stage and is successfully matched in the IOU matching stage, confirming the track which is successfully matched with the IOU according to the appearance cosine distance, and taking the confirmed track which is successfully matched with the IOU as the track which is successfully matched in the IOU matching stage; and tracking the customer according to the successfully matched tracks in the cascade matching stage and the IOU matching stage. According to the invention, the accuracy of customer tracking can be improved, and the probability of mismatching is reduced.

The present disclosure provides a data processing method, including: obtaining a target data set from a database according to an identification information set, wherein the data in the target data set is data decoupled from the business; storing the data in the target data set in a cache; traversing the data in the database to determine the target data, wherein the target data is the changed data in the target data set; and using the target data to update the associated data in the cache, wherein the associated data is the data already stored in the cache and having the same identification information as the target data. The present disclosure also provides a data processing device, a computer system, a readable storage medium, and a computer program product.
