Curse dimensionality
WebAnswer (1 of 3): The term comes from computer science, specifically Richard Bellman. When you set up data matrices to handle data each dimension multiplies the storage necessary. A (whimsical) example might be in order. Let’s say you are tracking how much money ten people spend on ten differen... WebThe curse of dimensionality refers to the problem of increased sparsity and computational complexity when dealing with high-dimensional data. In recent years, the types and variables of industrial data have increased significantly, making data-driven models more challenging to develop. To address this problem, data augmentation technology has …

WebThe curse of dimensionality is a term introduced by Bellman to describe the problem caused by the exponential increase in volume associated with adding extra dimensions to Euclidean space (Bellman, 1957 ). Curse of Dimensionality. Figure 1 The ratio of the volume of the hypersphere enclosed by the unit hypercube. WebMar 8, 2024 · Luckily the curse of dimensionality need not mean that we can’t build efficient models. Often we have some smoothness guarantees on the data, the space of the data is not populated so densely or the dimensionality can be reduced(a big part of machine learning research). Perhaps the best example for this is the space of all …
