Gift-Wrapping Based Preimage Computation Algorithm
Based on a classical convex hull algorithm called Gift-Wrapping, the purpose of the paper is to provide a new algorithm for computing the vertices of a polytope called preimage - ...

Connecting the Out-of-Sample and Pre-Image Problems in Kernel Methods
Kernel methods have been widely studied in the field of pattern recognition. These methods implicitly map, "the kernel trick," the data into a space which is more approp...

Learning to Find Pre-Images
We consider the problem of reconstructing patterns from a feature map. Learning algorithms using kernels to operate in a reproducing kernel Hilbert space (RKHS) express their solu...

MD4 is Not One-Way
MD4 is a hash function introduced by Rivest in 1990. It is still used in some contexts, and the most commonly used hash function (MD5, SHA-1, SHA-2) are based on the design princip...
