General statistical term for a model that fits the training data too closely and fails to generalize.
Regularization techniques are often used to prevent overfitting.
overfitting (in machine learning)
Specifically in machine learning; synonymous with 過学習.
See also: 過学習
This model overfits the training data, resulting in low accuracy on the test data.
Synonym for overfitting in machine learning contexts; 過剰適合 is slightly more formal and used in statistics as well.
Compound of 過剰 (excess) and 適合 (fitting, adaptation). A calque of English 'overfitting'.
