Better Text Compression Using A Large Language Model, D Shin

Defensive Publications Series

Conventional compression techniques for text are based on typical frequencies of individual letters within the text, independent of higher-level semantics. This disclosure describes a compression scheme for text data in which a conventional coder/decoder (codec) is augmented with an additional semantic codec to achieve greater compression and throughput. The additional semantic codec can be implemented with a pre-trained large language model (LLM). Text data is first input to a semantic coder for semantic-based compression. Codes within the codebook are reranked based on selective erasure by the encoder LLM. Once the codebook is established, portions within the text that can be …

Self-Healing For Paper Amount Metering Systems, Hp Inc

Defensive Publications Series

Paper Amount Metering Systems (also called Media Stack Height Measurement, in the specific case of Cut Sheet Trays), rely on some form of sensing system, that interacts either directly, or indirectly, with the amount of paper present for the Media Source, be it Roll, or Cut Sheets. The most critical function of such Metering Systems is to be able to give advanced warning, that media is about to run out (which is known as Low-on-Paper (LoP) or Low-Remaining-Paper-On-Roll), rather than the more legacy ability to sense Out-of-Paper (OoP). This is especially useful for remote printing cases, where users are not …
