2. Overfitting - Wikipedia

   en.wikipedia.org/wiki/Overfitting

   Underfitting is the inverse of overfitting, meaning that the statistical model or machine learning algorithm is too simplistic to accurately capture the patterns in the data. A sign of underfitting is that there is a high bias and low variance detected in the current model or algorithm used (the inverse of overfitting: low bias and high variance).

3. Multicollinearity - Wikipedia

   en.wikipedia.org/wiki/Multicollinearity

   Including collinear variables does not reduce the predictive power or reliability of the model as a whole, [6] and does not reduce the accuracy of coefficient estimates. [ 1 ] High collinearity indicates that it is exceptionally important to include all collinear variables, as excluding any will cause worse coefficient estimates, strong ...

   en.wikipedia.org/wiki/Oversampling_and_under...

   Data augmentation in data analysis are techniques used to increase the amount of data by adding slightly modified copies of already existing data or newly created synthetic data from existing data. It acts as a regularizer and helps reduce overfitting when training a machine learning model. [8] (See: Data augmentation)

6. Isotonic regression - Wikipedia

   en.wikipedia.org/wiki/Isotonic_regression

   In statistics and numerical analysis, isotonic regression or monotonic regression is the technique of fitting a free-form line to a sequence of observations such that the fitted line is non-decreasing (or non-increasing) everywhere, and lies as close to the observations as possible.

9. Curve fitting - Wikipedia

   en.wikipedia.org/wiki/Curve_fitting

   Fitting of a noisy curve by an asymmetrical peak model, with an iterative process (Gauss–Newton algorithm with variable damping factor α).Curve fitting [1] [2] is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, [3] possibly subject to constraints.
