Two and three-dimensional test cases were simulated using a detailed kinetic mechanism for methane combustion as a subset for di-methyl ether. A generic piston-bowl assembly for the compression and expansion strokes is utilized at 1500 RPM. A fine grid was used for the 2-D simulations and a rather coarse grid was used for the 3-D calculations together with a k-ε subgrid-scale turbulence model a...

In this paper, we present and analyze a novel regularization technique based on enhancing our dataset with corrupted copies of the original data. The motivation is that since the learning algorithm lacks information about which parts of the data are reliable, it has to produce more robust classification functions. We then demonstrate how this regularization leads to redundancy in the resulting ...
