arXiv paper argues linear models remain effective in complex domains

A new paper published on arXiv explores why linear models can still be effective for prediction in complex, nonlinear domains, even when the underlying mechanisms are intricate. The authors argue that this phenomenon occurs when the complexity of the real world exceeds what can be reliably learned from finite, partially observed data. In such scenarios, highly flexible models might overfit to specific training environments, leading to poorer performance in new settings, whereas simpler linear models can offer greater cross-environment stability and thus lower prediction error.

IMPACT Suggests that simpler models may offer greater robustness in real-world applications where data is limited and environments change.
