A Byte-Pair Encoding (BPE) tokenizer works by grouping frequently occurring pairs of characters instead of splitting text into words or individual characters. By training on a Sindhi Twitter dataset, this tokenizer captures common letter combinations in Sindhi, preserving the language's phonetic structure.
The key advantage of BPE is its ability to handle unknown words. Similar to how we can pronounce a new word by recognizing character pairings, the BPE tokenizer breaks down unfamiliar words into smaller, familiar sub-units, making it robust for unseen terms while maintaining consistency with the language's sound patterns.
