Meta researchers have released an open-source package called Balance that simplifies survey bias correction using methods like IPW, CBPS, and post-stratification. This tool allows researchers to adjust biased samples to better match target populations. Separately, a new method called TUR-DPO has been introduced for optimizing AI models, which considers topology and uncertainty to improve alignment by rewarding reasoning structure over simple binary outcomes.
