Research on Optimization of Machine Translation Performance Based on Deep Learning Algorithm
摘要
This article aims to solve the problem of scarce data from a single corpus and difficulty in learning the correspondence between the source and target languages. It uses a multi-translation parallel corpus for neural machine translation (NMT) research: extracting data from multiple parallel corpora and cleaning them, constructing a NMT model based on the transformer architecture. It uses Xavier for parameter initialization and unfolds model training through backpropagation and stochastic gradient descent algorithms. This article adopts the bagging method to integrate different parameter models and optimizes translation results based on language models and phrase tables. The research results indicate that the Bilateral Evaluation Understudy (BLEU) of the paper’s model in the Europarl corpus is 0.84, which is approximately 5.0% higher than the Generative Pre-trained Transformer (GPT). The improvement method adopted can achieve more accurate NMT in data scarcity scenarios.
