- Abstract: Recent advances in language modeling have led to computationally intensive
and resource-demanding state-of-the-art models. In an effort towards
sustainable practices, we study the impact of pre-training data volume on
compact language models. Multiple BERT-based models are trained on gradually
increasing amounts of French text. Through fine-tuning on the French Question
Answering Dataset (FQuAD), we observe that well-performing models are obtained
with as little as 100 MB of text. In addition, we show that past critically low
amounts of pre-training data, an intermediate pre-training step on the
task-specific corpus does not yield substantial improvements.

Learn-Focus-Review (LFR) is a dynamic training approach that adapts to the model's learning progress.
LFR tracks the model's learning performance across data blocks (sequences of tokens) and prioritizes revisiting challenging regions of the dataset.
Compared to baseline models trained on the full datasets, LFR consistently achieved lower perplexity and higher accuracy.
