Self-Consistency: Majority Vote
Intermediate
The problem, from first principles
Self-consistency (Wang et al., 2022) samples several reasoning paths at a non-zero temperature, then takes the answer most paths agree on. It replaces greedy decoding with a vote over diverse reasoning.
From theory to code
Implement majority_vote(answers), returning the most frequent answer with ties broken by first appearance.
Constraints
- Ties go to the earliest answer.
Hints
Hint 1
Count occurrences, then return the answer with the highest count, scanning in order so ties keep the earlier one.
