👉 Proximation is a technique used in machine learning and data analysis to approximate the behavior or distribution of a function at a given point. It involves finding an estimate (prox) of the function's value at that point, based on its values within a certain range. Proximity algorithms can be used for both smooth and non-smooth functions, while they are commonly used in regression tasks like linear least squares, which aim to find a line or plane that best fits a dataset.
