Ridgelets: a key to higher-dimensional intermittency?
higher-dimensional intermittency wavelets
2015/8/21
We discuss in this paper a new subject, ridgelet analysis, which can e®ectively
deal with linelike phenomena in dimension 2, planelike phenomena in dimension
3 and so on. It encompasses a colle...

We show that ridgelets, a system introduced in [4], are optimal to represent smooth multivariate functions that may exhibit linear singularities. For instance, let {u · x − b > 0} be an arbitrar...
