The n-dimensional hypervolume
WebApr 13, 2024 · Non-negative matrix factorization (NMF) establishes a low-rank approximation to the input matrix in a low-dimensional space. To do so, matrix X N×n is decomposed into X ≈ W H, where W denotes an N × p (score) matrix, H represents a p × n (loading) matrix. The number of reduced components p is significantly less than n (p ≪ n). WebMay 14, 2024 · n-dimensional hypervolume framework.

WebJul 7, 2024 · The n-dimensional hypervolume was originally proposed by Hutchinson (1957) to describe the fundamental niche of a species. These hypervolumes exist within a space defined by a set of n independent axes. The hypervolume is then defined as a subset of the space, i.e. an n-dimensional geometrical shape (Fig. 1A). WebOct 31, 2024 · Useful in quantifying and comparing species's niches, an n -dimensional hypervolume represents the hypothetical space that a species occupies according to a set of ' n ' variables, or niche dimensions. Each axis of the multi-dimensional graph quantifies one biologically important variable. The shape of the hypervolume encompasses data …
