It breaks down words into smaller subword units to manage morphological richness and reduce vocabulary size. The algorithm starts with a base vocabulary and iteratively adds the most frequent character pairs until a target size is reached. This allows the model to represent rare or unseen words by combining known subwords, improving generalization and handling of linguistic variations effectively.</p>
