• Abstract summary: This paper evaluates the impact of data filtering techniques on English-Polish translation within the biomedical domain. We created varying dataset sizes to fine-tune the mBART50 model, which was then evaluated using the SacreBLEU metric. Our results show that both LASER and MUSE can significantly reduce dataset sizes while maintaining or even enhancing performance.

• Abstract: Large Language Models (LLMs) have become state-of-the-art in Machine Translation (MT), often trained on massive bilingual parallel corpora scraped from the web, that contain low-quality entries and redundant information, leading to significant computational challenges. Various data filtering methods exist to reduce dataset sizes, but their effectiveness largely varies based on specific language pairs and domains. This paper evaluates the impact of commonly used data filtering techniques, such as LASER, MUSE, and LaBSE, on English-Polish translation within the biomedical domain. By filtering the UFAL Medical Corpus, we created varying dataset sizes to fine-tune the mBART50 model, which was then evaluated using the SacreBLEU metric on the Khresmoi dataset, having the quality of translations assessed by bilingual speakers. Our results show that both LASER and MUSE can significantly reduce dataset sizes while maintaining or even enhancing performance. We recommend the use of LASER, as it consistently outperforms the other methods and provides the most fluent and natural-sounding translations.

  ScalingFilter is a novel approach that evaluates text quality based on the perplexity difference between two language models trained on the same data. To assess the bias introduced by quality filtering, we introduce semantic diversity, a metric of utilizing text embedding models for semantic representations.

The quality of the translations in the experiment is evaluated using standard metrics such as BLEU, METEOR, and RIBES.

  We examine how denoising autoencoding (DAE) and backtranslation (BT) impact machine translation (MMT) We find that monolingual data generally helps MMT, but models are surprisingly brittle to domain mismatches, especially at smaller model scales. As scale increases, DAE transitions from underperforming the parallel-only baseline at 90M to converging with BT performance at 1.6B, and even surpassing it in low-resource.

  Language coverage bias is important for neural machine translation (NMT) because the target-original training data is not well exploited in current practice.

We propose two simple and effective approaches to alleviate the language coverage bias problem.
