How can the findings from this study be applied to other underrepresented languages in NLP research

The findings from this study can be applied to other underrepresented languages in NLP research by serving as a framework for optimizing computational resources and model performance. By understanding the impact of tokenization output length, text-shortening strategies, and hyperparameter optimization on model efficiency and effectiveness, researchers working with underrepresented languages can tailor their approaches to make the most out of limited resources. For instance, identifying recommended models based on tokenizer output length can help select models that are more suitable for processing longer texts efficiently. Additionally, implementing effective text-shortening strategies like removing stopwords while preserving essential information can enhance model performance within resource constraints. Moreover, adopting a dynamic hyperparameter optimization procedure similar to the one proposed in the study can enable researchers to fine-tune models effectively even with limited GPU capabilities.

What are potential drawbacks or limitations of relying on free computational services like Google Colab

Relying on free computational services like Google Colab comes with potential drawbacks and limitations that researchers need to consider. One major limitation is the restricted access to high-performance computing resources such as GPUs or TPUs, which may hinder complex computations required for training large Transformer models efficiently. Free services often have usage quotas or restrictions on runtime duration, leading to interruptions during training sessions or limiting the size of datasets that can be processed effectively. Furthermore, data privacy concerns may arise when sensitive information is processed using third-party platforms like Google Colab.
Another drawback is the lack of customization options and control over hardware configurations compared to dedicated cloud computing services or local setups. This limitation could impact the scalability and reproducibility of experiments across different environments. Additionally, reliance on free services may result in variability in performance due to shared resources among users, potentially affecting experiment consistency.
