The size of the corpus has a significant impact on the quality of contextualized embeddings. Contextualized embeddings are representations of words or phrases in a given context, and they are learned through training on a large amount of text data.

  A larger corpus size allows for a broader range of contextual information to be captured during the training process. It provides more diverse examples of how a word or phrase can be used in different contexts, which helps the model to learn more accurate and meaningful representations.

  With a larger corpus, the model has access to a wider variety of contexts, including different domains, topics, styles, and variations in language usage. This exposure to diverse contexts helps contextualized embeddings capture the nuances and subtleties of language more effectively.

  Furthermore, a larger corpus helps to mitigate the impact of any biases or anomalies present in a smaller dataset. By training on a larger dataset, the model is exposed to a more balanced distribution of language patterns, reducing the risk of overfitting to specific language patterns present in a smaller corpus.

  On the other hand, a smaller corpus size may not encompass enough examples to adequately capture the full range of contextual information. This can result in less robust and less accurate representations, as the model may have limited exposure to various language contexts.

  However, it is worth noting that there may be diminishing returns beyond a certain corpus size. Once the model has been exposed to a sufficient amount of diverse and representative training data, additional data may not provide significant improvements in the quality of contextualized embeddings.

  In summary, the size of the corpus directly influences the quality of contextualized embeddings. A larger corpus allows for better capture of contextual information, leading to more accurate and meaningful representations.
