Abstract

The invention discloses a sample expansion method, device and equipment and a computer readable storage medium, and relates to the technical field of financial science and technology. The sample expansion method comprises the following steps: extracting a training sample group from an initial training sample set, wherein the training sample group comprises a statement text and a sample label; processing the statement text to obtain a corresponding sample sentence vector; and obtaining a weight coefficient, mixing the sample sentence vector and the sample label based on the weight coefficient,and constructing an extended training sample according to a mixing result. The method can achieve the expansion of the training sample, and can facilitate the improvement of the model training effect.

Description

technical field [0001] The present invention relates to the technical field of financial technology (Fintech) data processing, in particular to a sample expansion method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually transforming into Fintech. However, due to the security and real-time requirements of the financial industry, higher requirements are placed on technology. requirements. [0003] In the field of human-computer dialogue, intent recognition is one of the core technologies, and the understanding of natural semantics is one of the prerequisites for the realization of human-computer dialogue. Intent recognition, that is, to extract the intention from the user's question. At present, the intention recognition model is mainly used to identify the intention of the user's q...
