Problems solved by technology

It can be seen that although this method increases the number of training samples, it also increases the error noise
In fact, the data added by word replacement and back-translation are fake data. While increasing the number of training samples, it also introduces a lot of noise, which increases the difficulty of machine learning, and requires fine-tuning of the replacement rate and noise rate. Adjustment, so the workload is heavy and not flexible enough

Abstract

The invention relates to a training sample enhancement method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first source language statement and an associated statement of the first source language statement; splicing at least one statement in the associated statements with the first source language statement to obtain a second source language statement; determining a second target language statement according to the second source language statement; and forming a statement pair by the second source language statement and the second target language statement, and taking the statement pair as a training sample. The second source language statement is real data instead of pseudo data, so that the negative influence of noise generated by the pseudo data on the machine translation model can be reduced or avoided.

Description

Technical field [0001] The present application relates to the field of machine translation technology, particularly to a method and apparatus for enhancing the training samples, machine translation model training method and apparatus, computer equipment, and storage media. Background technique [0002] Currently, machine translation is a translation obtained by the model training sample translation to translate the source language into the target language. The translation model training requires a lot of training samples, training sample that is the source language and the target language sentence right, its high acquisition costs, especially in minority languages, the need for specialized translators are labeled, so more and more popular in the technical staff to expand the training sample data through enhanced ways to reduce costs. [0003] Currently, data enhancement methods are replacing words, back translation methods. Among them, the words replace, for example, "this cool a...
