Web1 apr 2024 · In high dimensional spaces, whenever the distance of any pair of points is the same as any other pair of points, any machine learning model like KNN which depends a lot on Euclidean distance, makes no more sense logically. Hence KNN doesn’t work well when the dimensionality increases. WebHigh Dimensional Data just means that the number of dimensions or attributes is huge. Staggeringly high. You have added so many layers and characteristics that any …

WebHigh-dimensional dataare defined as data in which the number of features (variables observed), $p$, are close to or larger than the number of observations (or data points), $n$. The opposite is low-dimensional datain which the number of observations, $n$, far outnumbers the number of features, $p$.
