Learning from Biased and Costly Data Sources: Minimax-optimal Data Collection under a Budget

Researchers have developed a new method for collecting data from multiple sources under budget constraints, focusing on estimating population means and group-specific averages. This technique maximizes effective sample size by accounting for differences in sampling costs and biases across various groups, offering content creators a more efficient way to gather accurate data despite heterogeneous source characteristics.
