Optimizing Binary Feature Vector Similarity Measure using Genetic Algorithm and Handwritten Character Recognition
Classifying an unknown input is a fundamental problem in pattern recognition. A common method is to define a distance metric between patterns and find the most similar pattern i...

A Randomized Online Learning Algorithm for Better Variance Control
We propose a sequential randomized algorithm, which at each step concentrates on functions having both low risk and low variance with respect to the previous step prediction functi...

Wavelet-Based Super-Resolution Reconstruction: Theory and Algorithm
We present an analysis and algorithm for the problem of super-resolution imaging, that is the reconstruction of HR (high-resolution) images from a sequence of LR (lowresolution) im...

Transforming cabbage into turnip: polynomial algorithm for sorting signed permutations by reversals
Genomes frequently evolve by reversals ␳(i, j) that transform a gene order ␲1 . . . ␲i␲iϩ1 . . . ␲jϪ1␲j . . . ␲n into ␲1 . . . ␲i␲jϪ1 . . . ␲iϩ1␲j . . ....

MultiK-MHKS: A Novel Multiple Kernel Learning Algorithm
In this paper, we develop a new effective multiple kernel learning algorithm. First, we map the input data into m different feature spaces by m empirical kernels, where each genera...
