Researchers have introduced Best-of-Better-N (BoBN), a novel in-context learning framework designed to enhance the alignment of responses generated by large language models. This method addresses limitations in existing inference-time alignment techniques by retrieving high-reward examples relevant to a given query and then restyling these examples to match the target task's format and style. The framework analytically demonstrates how in-context learning can shift a pre-trained transformer's output distribution towards higher rewards, offering provable benefits. Evaluations on safety alignment and mathematical reasoning benchmarks show that BoBN achieves better performance with a fixed number of responses or requires a smaller number of responses to reach a target performance level.
