Aligning Model Properties via Conformal Risk Control

Neural Information Processing Systems 

AI model alignment is crucial due to inadvertent biases in training data and the underspecified machine learning pipeline, where models with excellent test metrics may not meet end-user requirements. While post-training alignment via human feedback shows promise, these methods are often limited to generative AI settings where humans can interpret and provide feedback on model outputs. In traditional non-generative settings with numerical or categorical outputs, detecting misalignment through single-sample outputs remains challenging, and enforcing alignment during training requires repeating costly training processes.In this paper we consider an alternative strategy. We propose interpreting model alignment through property testing, defining an aligned model f as one belonging to a subset \mathcal{P} of functions that exhibit specific desired behaviors. We focus on post-processing a pre-trained model f to better align with \mathcal{P} using conformal risk control.
