roll out parent states to obtain paired child states and select state pairs with value differences larger than a specified thresh- old. After obtaining preference data, we perform process-based preference learning using direct pref- erence optimization (DPO) (Rafailov et al., 2024) to self-improve the TQA model. Experi...
