Byte-Pair Encoding compression bound improved to 0.361

By PulseAugur Editorial · [1 sources] ·

A new paper published on arXiv details a theoretical advancement in the field of data compression, specifically concerning Byte-Pair Encoding (BPE). Researchers have proven that the greedy approach used in BPE consistently achieves at least 0.361 of the optimal compression, improving upon the previously established one-third bound. This work also explores the structural properties of optimal compression and the challenges in achieving better theoretical bounds. AI

IMPACT This theoretical advancement in data compression could potentially lead to more efficient tokenization methods for large language models.

    Greedy Byte-Pair Encoding Achieves at Least 0.361 of the Optimal Compression

    arXiv:2611.08671v1 Announce Type: cross Abstract: Byte-Pair Encoding (BPE) builds a tokeniser by repeatedly merging a most frequent adjacent pair of symbols; its utility is the total reduction in string length achieved by $k$ merges. It was known that this greedy rule achieves at…
