  • Patent number: 11847565
    Abstract: Methods and apparatuses are described for automatic refinement of intent classification for virtual assistant applications. A computing device creates utterance groups comprising messages. The device determines, using a first machine learning (ML) classifier, a first predicted intent associated with each utterance group and determines, using a second ML classifier, a second predicted intent associated with each utterance group. The device combines the first and second predicted intents to generate a final predicted intent, determines, for each incomprehensible utterance group, whether the final predicted intent overlaps with the final predicted intent for other utterance groups, and selects messages having no overlapping intent to create new intents.

  • Patent number: 11842046
    Abstract: A storage fragment management method and a terminal. The method may be applied to a file system of the terminal, and the file system includes at least one segment. The method includes: first determining, by the terminal, a source segment from the file system based on an aging degree of the segment and a valid block ratio of the segment; then determining, by the terminal from the file system based on an aging degree of the source segment, a target segment whose aging degree is consistent with the aging degree of the source segment; and finally migrating, by the terminal, data of a valid block in the source segment to an idle block in the target segment. This method is used to resolve a problem that power consumption is high when data migration is performed on a storage fragment in an existing log-structured file system.
