WebOct 18, 2024 · BPE Algorithm – a Frequency-based Model Byte Pair Encoding uses the frequency of subword patterns to shortlist them for merging. The drawback of using frequency as the driving factor is that you can end up having ambiguous final encodings that might not be useful for the new input text. Web3.2 Byte Pair Encoding (BPE) Byte Pair Encoding (BPE) (Gage, 1994) is a sim-ple data compression technique that iteratively re-places the most frequent pair of bytes in a se-quence with a single, unused byte. We adapt this algorithm for word segmentation. Instead of merg-ing frequent pairs of bytes, we merge characters or character sequences.

The Modern Tokenization Stack for NLP: Byte Pair Encoding

Byte pair encoding (BPE) or digram coding is a simple and robust form of data compression in which the most common pair of contiguous bytes of data in a sequence are replaced with a byte that does not occur within the sequence. A lookup table of the replacements is required to rebuild the … See more Byte pair encoding operates by iteratively replacing the most common contiguous sequences of characters in a target piece of text with unused 'placeholder' bytes.
