Dimensionalityin statistics refers tohow many attributes a dataset has. For example, healthcare data is notorious for having vast amounts of variables (e.g. blood pressure, weight, cholesterol level). In an ideal world, this data could be represented in a spreadsheet, with one column representi...
Curse of Dimensionality. Figure1 The ratio of the volume of the hypersphere enclosed by the unit hypercube. The most intuitive example, the unit square and unit circle, are shown as an inset. Note that the volume of the hypersphere quickly becomes irrelevant for higher dimensionality For ...
Curse of Dimensionality refers to non-intuitive properties of data observed when working in high-dimensional space *, specifically related to usability and interpretation of distances and volumes. This is one of my favourite topics in Machine Learning and Statistics since it has broad applications (no...

It’s already getting tough, trying to search a (roughly) football ground for a single coin. But what if it’s 100 x 100 x 100 cu.m space?! You know, football ground now has thirty-story height. Good luck finding a coin there! That, in essence is “curse of dimensionality”. ...
This practical example hints to a common picture typically shown whenever ‘curse of dimensionality’ is discussed (taken fromnewsnshit): You can see that the number of data points that are captured by some fixed ‘length’ (in our previous example this is equivalent to the 10%) is rapidly...
In a previouspostwe discussed the term ‘curse of dimensionality’ and showed how it manifests itself, in practice. Here we give another such example. Forecast combinations Here is another situation where the ‘curse of dimensionality’ morph an excellent idea in small dimension into an impossible...
Curse of dimensionality (Bellman 1961) refers to the exponential growth of hypervolume as a function of dimensionality. In the field of NNs, curse of dimensionality expresses itself in two related problems: 1. Many NNs can be thought of mappings from an input space to an output space. Thus...
