Sliver removal by lattice refinement
I present an algorithm that can provably eliminate slivers in the interior of a tetrahedral mesh, leaving only tetrahedra with dihedral angles between 30 and 135 degrees and radiu...

A General Approach to Removing Degeneracies
We wish to increase the power of an arbitrary algorithm designed for non-degenerate input, by allowing it to execute on all inputs. We concentrate on in nitesimal symbolic perturba...

Avoiding Boosting Overfitting by Removing Confusing Samples
Boosting methods are known to exhibit noticeable overfitting on some datasets, while being immune to overfitting on other ones. In this paper we show that standard boosting algorit...
