Self-Consistency
Definition
Self-consistency aggregates multiple generated solution paths by their final answers.
A decoding method introduced in a research paper that generates multiple stochastically produced solution paths for the same task and aggregates the final answer by frequency.
Simply explained
The model solves the same task multiple times and selects the answer that occurs most frequently.
Why it matters in practice
The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.
Example from business
A model generates twenty reasoning paths and selects the majority answer.
Limits and pitfalls
- Equating majority or plurality answers with truth, producing too little diversity, ignoring correlated model errors, or not limiting computational costs and sensitive intermediate texts.
Origin & history
Wang and co-authors published Self-Consistency in 2022 for Chain-of-Thought prompting.
Use in mid-sized companies
- Possible example: A model generates twenty reasoning paths and selects the majority answer.
