Researchers have developed a new method called Counterfactual-Faithful Quantization (CFQ) to address issues with model quantization in decision systems that offer algorithmic recourse. Standard quantization can alter the effectiveness of recourse actions, requiring larger interventions or failing entirely. CFQ is a quantization-aware training technique that jointly optimizes quantizer parameters and bit allocation to maintain prediction stability at recourse points. Experiments on datasets like Adult and COMPAS demonstrate that CFQ significantly reduces recourse instability compared to accuracy-centric baselines while maintaining comparable accuracy and bit budgets.
