• Abstract: Orthographic variation is very common in Luxembourgish texts due to the absence of a fully-fledged standard variety. Additionally, developing NLP tools for Luxembourgish is a difficult task given the lack of annotated and parallel data, which is exacerbated by ongoing standardization. In this paper, we propose the first sequence-to-sequence normalization models using the ByT5 and mT5 architectures with training data obtained from word-level real-life variation data. We perform a fine-grained, linguistically-motivated evaluation to test byte-based, word-based and pipeline-based models for their strengths and weaknesses in text normalization. We show that our sequence model using real-life variation data is an effective approach for tailor-made normalization in Luxembourgish.

  Finetuning is a common practice across different communities to adapt pretrained models to particular tasks. ensembles of neural networks are typically used to boost performance and provide reliable uncertainty estimates. We present a metadataset with predictions from five large finetuned models on six datasets and report results of different ensembling strategies.

  This study proposes a new normalization technique, called context normalization, for image data. It adjusts the scaling of features based on the characteristics of each sample, which improves the model's convergence speed and performance. The effectiveness of context normalization is demonstrated on various datasets, and its performance is compared to other standard normalization techniques.

  We show the effectiveness of character-level modeling in translation, particularly in cases where fine-tuning data is limited. While evaluating the importance of source texts in driving model predictions, we highlight word-level patterns within ByT5. We conclude by assessing the efficiency tradeoff of byte models, suggesting their usage in non-time-critical scenarios to boost translation quality.

We present plT5 - a general-purpose text-to-text model for Polish that can be fine-tuned on various Natural Language Processing (NLP) tasks with a single training objective.

  Current benchmark tasks for natural language processing contain text that is qualitatively different from the text used in informal day to day digital communication. This discrepancy has led to severe performance degradation of state-of-the-art NLP models when fine-tuned on real-world data. We propose a sentence-level sequence-to-sequence model based on mBART, which frames the problem as a machine translation problem.

  Formality style transfer is the task of converting informal sentences to grammatically-correct formal sentences.

Experiments showed that our model outperformed previous state-of-the-art baselines significantly in terms of both automated metrics and human judgement.
