New NCO plug-in enhances LLM control over undesirable content

Researchers have developed NCO, a new decoding strategy designed to enhance control over Large Language Model (LLM) outputs. This plug-in addresses the challenge of preventing multiple forbidden patterns, such as profanity or personally identifiable information (PII), from appearing in generated text. NCO achieves this by performing efficient online pattern matching, avoiding the state explosion issues common with converting multiple constraints into a single automaton. The strategy is compatible with standard inference methods and has demonstrated effectiveness in practical applications. AI
