  • Publication number: 20250061345
    Abstract: Disclosed herein a model stability detection method and apparatus, and a device. Base period labeled samples and base period unlabeled samples at a base period time point, and current period unlabeled samples at a current period time point are obtained. A base period decision tree model is trained using the base period labeled samples. The base period decision tree model includes at least one path from a root node to a leaf node. Applying the base period decision tree model to form a first set of numerical values and second set of numerical values. Due to a distribution change of the input data in the samples, the sample statistics are different. Therefore, occurrence of data drift can be determined based on a first distribution difference result of the first set of numerical values and the second set of numerical values, to implement model stability detection.

  • Publication number: 20250036885
    Abstract: The present application discloses a language model processing method and apparatus. The method includes: constructing N storage structures to store an N-gram language model. For an ith structure, if i is greater than or equal to 1 and less than or equal to N?1, the ith storage structure includes a plurality of first nodes, the first node is used to carry information about an ith-order word in a first gram; or if i is equal to N, the ith storage structure includes a plurality of second nodes, the second node carries information about a second gram, the second gram is an N-gram, and the information carried by the second node includes: an identifier of an Nth-order word in the second gram and an N-gram probability of the second gram.

  • Publication number: 20250021878
    Abstract: The present invention relates to the technical field of data processing, and discloses a method and apparatus, computer device, and storage medium for generating an augmented sample. The method includes: obtaining a reference sample set to be augmented, and selecting at least two parent samples from the reference sample set; generating a new sample based on the at least two parent samples; updating feature values of the first type of features based on first statistical data of the first type of features in the reference sample set, and updating classification options of the second type of features based on second statistical data of the second type of features in the reference sample set; and generating an augmented sample based on the updated feature values of the first type of features and the updated classification options of the second type of features.
