WitrynaLocal Intrinsic Dimensionality (LID): Definition (Local Intrinsic Dimensionality) Given a data sample ∈𝑋, let 𝑟>0be a random variable denoting the distance from to other data … Local intrinsic dimensionality (LID) refers to the observation that often data is distributed on a lower-dimensional manifold when only considering a nearby subset of the data. For example the function can be considered one-dimensional when y is close to 0 (with one variable x), two-dimensional when y is close to 1, and again one-dimensional when y is positive and much larger than 1 (with variable x+y).

Intrinsic dimensionality measures the average ID in an entire dataset, whereas LID measures the intrinsic dimension around a point. Local intrinsic dimensionality (LID) refers to the observation that often data is distributed on a lower-dimensional manifold when only considering a nearby subset of the data.
