Feb 5, 2023 · Delving into the depths of linear algebra, one encounters the powerful Gram-Schmidt Process, a mathematical algorithm that transforms a set of vectors into an orthogonal or orthonormal basis. It’s a fascinating process, fundamental to numerous areas in mathematics and physics, including machine learning, data compression, and quantum mechanics. 7.4. Let v1; : : : ; vn be a basis in V . Let w1 = v1 and u1 = w1=jw1j. The Gram- Schmidt process recursively constructs from the already constructed orthonormal set u1; : : : ; ui 1 which spans a linear space Vi 1 the new vector wi = (vi proj Vi (vi)) which is orthogonal to Vi 1, and then normalizes wi to get ui = wi=jwij.May 29, 2023 · Step-by-Step Gram-Schmidt Example.
