WebJan 28, 2024 · Byte-Pair Encoding was originally a compression algorithm where we replace the most frequent byte pair with a new byte - thereby compressing the data. For … WebEssentially, BPE (Byte-Pair-Encoding) takes a hyperparameter k, and tries to construct <=k amount of char sequences to be able to express all the words in the training text corpus. RoBERTa uses byte-level BPE, which sets the base vocabulary to be 256, i.e. how many unicode characters there are. WebByte Pair Encoding (BPE) ... The tokenizer will then have a base vocabulary only based on the unique bytes present in the training data. If you set this argument to True, you should probably then use the tokenizer only with the training data, as new data might contain “unknown” tokens missing from the vocabulary. ... hotpoint h3x81iw fridge freezer
