The curse of dimensionality is a phenomenon that appears in Machine Learning models when algorithms must learn from an ample feature volume with abundant values within each one. Reaching samples with each combination of values when training would be very complicated. Thus, it can happen (as it ...
Let's get a rough idea of how the difficulty of a machine learning problem increases as the dimensionality increases. According to astudyby C.J. Stone in 1982, the time it takes to fit a model (specifically a nonparametric regression) to your data is at best proportional to m^{-p/(2p...
phenomenon known as “the curse of dimensionality” in statistical learning theory. We provide an overview of the curse of dimensionality in the context of digital health, demonstrate how it can negatively impact out-of-sample performance, and highlight important considerations for researchers and algo...
The curse of dimensionality was formulated bytheAmerican mathematician Richard Bellmanin the context of dynamic programming and optimization, and it has since become almost synonymous with high-dimensional statistical learning. We are concerned about the curse of dimensionality because the basic principle o...

Curse of dimensionality Evenwith the advances in computational power, big data is hard for machine learning algorithms to manage. In general, adding more instances is not too problematic because we can parallelize operations using modern map-reduce solutions such as Spark. However, the more features...
