A new research paper argues that measurement noise, rather than model limitations, is the primary factor hindering the performance of nonlinear models in biomedical prediction tasks. The study suggests that additive noise erases nonlinear structures faster than linear ones, diminishing the advantage of complex models. The authors propose that improving measurement reliability, alongside sample size and feature representation, is crucial for flexible models to offer benefits, a condition rarely met in most biomedical applications.
