报告摘要:Data acquisition is an important task in data-driven business analytics. This work studies data acquisition problem concerning both data quality and acquisition cost. We propose using a divide-and-conquer technique to characterize the empirical distribution of the target population. We explore the idea of using auctions to acquire customer data and analyze the acquisition cost. We formulate the acquisition problem as an optimization problem that maximizes the utility of the acquired data while satisfying acquisition budget. For descriptive analytics, we derive the analytical form of the solution for the optimization problem, which finds a set of records that best represent the target population. For predictive analytics with linear regression, the objective is to minimize prediction error. We translate the optimization problem to a mathematical programming problem that can be solved efficiently. An experimental study has been conducted to demonstrate the effectiveness of our approach.
