CORE DEFINITION

The model fits the noise and details of the training data too closely, resulting in poor performance on new data.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

A warning about generalization ability, reminding that "performing well on known data" does not equal "performing well on unknown data."

anchor

Anchor fast decisions

The model captures noise in the training data as patterns, fitting too tightly, leading to poor generalization and failure on unseen data.

Berkson's Paradox

Berkson's paradox, also known as Berkson's bias, collider bias, or Berkson's fallacy, refers to the situation where people's intuitive observations do not match the actual conditional probabilities and rigorous statistical results; that is, the seemingly correlated factors that people discover are actually unrelated. This occurs when biased samples are included in the study design and bias exists. The paradox was proposed by American physician and statistician Joseph Berkson in 1946.
