In Vapnik–Chervonenkis theory, the Vapnik–Chervonenkis (VC) dimension is a measure of the capacity (complexity, expressive power, richness, or flexibility) of a set of functions that can be learned by a statistical binary classification algorithm. It is defined as the cardinality of the largest set of points that the … See more 1. $${\displaystyle f}$$ is a constant classifier (with no parameters); Its VC dimension is 0 since it cannot shatter even a single point. In general, the VC dimension of a finite classification model, which can return at … See more A finite projective plane of order n is a collection of n + n + 1 sets (called "lines") over n + n + 1 elements (called "points"), for which: • Each line contains exactly n + 1 points. • Each line intersects every other line in exactly one point. See more The VC dimension is defined for spaces of binary functions (functions to {0,1}). Several generalizations have been suggested for … See more In statistical learning theory The VC dimension can predict a probabilistic upper bound on the test error of a classification model.

WebJun 11, 2024 · The VC dimension is the maximal number of points that can be shattered. If the VC dimension of a classifier is 100, it still could be possible to find 3 points that cannot be shattered by the classifier. We could define the VCB dimension to be the largest number n such that all sets of size n or less can be shattered. WebJan 9, 2024 · Your Claim: The VC Dimension of a SVM fK equipped with kernel K can be defined as danyK + 1. Now, Just consider K = (x. y)2 with transformation ϕ(x) = ( x21 √2x1x2 x22). Just check that, ∄x ( = (x1, x2)) s.t ϕ(x) = ( x21 √2x1x2 x22) = (0 1 0) So this alone makes the first case of proof The VC-dimension of the set of linear classifiers is d invalid
