AI Technical Summary

Technical Problem

Existing intelligent dialogue systems cannot effectively detect unknown intents, resulting in poor user experience and an inability to provide services that meet user needs. Current technologies mainly rely on the current statement for detection.

Method used

The unknown intent detection model is trained by acquiring training data, including multiple samples labeled with known intent and unknown intent, using a feature extraction network and a classification network for training, combining generative adversarial networks and dropout mechanism to construct unknown intent samples, and taking into account the historical context of the input text for detection.

Benefits of technology

It improves the accuracy of unknown intent detection, reduces manual costs, enhances the robustness of the model and its ability to detect unknown intent, and enables a better understanding of dialogue semantics.
