MUFT: Multiplier-based Unfolding Transformation of Survey Data for Machine Learning-based Modelling
Multiplier-based Unfolding Transformation (MUFT) facilitates the efficient integration of survey data into machine learning workflows by adjusting for weights and transforming the data into a format suitable for model training, while preserving its representativeness. This transformation enables the seamless application of diverse machine learning algorithms to survey data with minimal loss of information, leading to accurate and generalizable models. In survey data analysis, using sample data directly in machine learning models presents significant challenges due to the presence of survey weights. These weights are essential for making the survey data representative of the target population, as they account for unequal probabilities of selection, non-response, and other sample design complexities. However, effectively incorporating these weights into machine learning models is challenging and can lead to biased or suboptimal predictions if not addressed properly.
