Web10 Apr 2024 · The algorithm analyzes the frequency of character combinations in the training text and iteratively merges the most frequent pairs to form new subword units. To tokenize text, BPE breaks it down into its constituent characters and applies the learned merge operations. WebSpecifically, the lexical encoder uses the sub-tokenized code as the input, where a complex code token (e.g., the function name mystrcopy) in Figure 4) is automatically broken down into sub-pieces (e.g., my, str, and copy) using SentencePiece , based on sub-token frequency statistics. Sub-tokenization reduces the size of the encoder's vocabulary (and thus its …
