Vines and vineyards by updating persistence in linear time
Persistent homology is the mathematical core of recent work on shape, including reconstruction, recognition, and matching. Its pertinent information is encapsulated by a pairing o...

Optimization of Linear Placements for Wirelength Minimization with Free Sites
We study a type of linear placement problem arising in detailed placement optimization of a given cell row in the presence of white-space (extra sites). In this single-row placeme...

A local linear embedding module for evolutionary computation optimization
A Local Linear Embedding (LLE) module enhances the performance of two Evolutionary Computation (EC) algorithms employed as search tools in global optimization problems. The LLE em...

Inpainting with sparse linear combinations of exemplars
We introduce a new exemplar-based inpainting algorithm that represents the region to be inpainted as a sparse linear combination of example blocks, extracted from the image being ...

Linear Recursive Functions
Abstract. With the recent trend of analysing the process of computation through the linear logic looking glass, it is well understood that the ability to copy and erase data is ess...
