Affine minorization
WebAug 21, 2024 · The main idea of DCA is approximating the second DC component H by its affine minorant and then solving the resulting convex subproblem at each iteration. The two important key issues while designing DCA are the search for a “good” DC decomposition and the solution method to efficiently solve convex subproblems.

However, the stretching and shearing transformations warp shapes, as the following example shows: This is an example of image warping. However, the affine transformations do not facilitate projection onto a curved surface or radial distortions. See more In Euclidean geometry, an affine transformation or affinity (from the Latin, affinis, "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances See more Let X be an affine space over a field k, and V be its associated vector space.
