Interpolation
In the field of machine learning (ML), interpolation refers to the process of estimating the value of a function or a dataset at points that lie between known data points. Interpolation is often used to fill in missing values in a dataset or to smooth out noise or irregularities in the data.
There are several different methods that can be used for interpolation in ML, including linear interpolation, polynomial interpolation, and spline interpolation. The choice of interpolation method will depend on the characteristics of the data and the goals of the analysis.
The straightforward process of linear interpolation includes fitting a straight line between two known data points and utilizing that line to calculate the function's value at the places in between. Although quick and simple to use, this method might not be appropriate for data with more intricate patterns.
Fitting a polynomial function to the data points during polynomial interpolation might be more flexible and suitable for data with complicated patterns. When data displays smooth, continuous trends, spline interpolation involves fitting a smooth curve to the data points.
In ML, interpolation can be used to fill in missing values in a dataset, which can be useful when working with incomplete or noisy data. It can also be used to smooth out irregularities in the data, which can help to improve the accuracy and robustness of machine learning models.
