Transferability and Hardness of Supervised Classification Tasks [PDF]
IEEE International Conference on Computer Vision, 2019 We propose a novel approach for estimating the difficulty and transferability of supervised classification tasks. Unlike previous work, our approach is solution agnostic and does not require or assume trained models.

Hardness-Aware Deep Metric Learning [PDF]
Computer Vision and Pattern Recognition, 2019 This paper presents a hardness-aware deep metric learning (HDML) framework. Most previous deep metric learning methods employ the hard negative mining strategy to alleviate the lack of informative samples for training.

Polydisperse hard spheres at a hard wall [PDF]
The Journal of Chemical Physics, 2004 The structural properties of polydisperse hard spheres in the presence of a hard wall are investigated via Monte Carlo simulation and density functional theory (DFT). Attention is focused on the local density distribution ρ(σ,z), measuring the number density of particles of diameter σ at a distance z from the wall.

Proceedings. Thirteenth Annual IEEE Conference on Computational Complexity (Formerly: Structure in Complexity Theory Conference) (Cat. No.98CB36247), 1999 AbstractWe investigate the frequency of complete sets for various complexity classes within EXP under several polynomial-time reductions in the sense of resource-bounded measure. We show that these sets are scarce: The sets that are ⩽pnα−tt-complete for NP, the levels of the polynomial-time hierarchy, and PSPACE have p2-measure zero for any constant ...

The Hall–Petch and inverse Hall–Petch relations and the hardness of nanocrystalline metals
Journal of Materials Science, 2019 We review some of the factors that influence the hardness of polycrystalline materials with grain sizes less than 1 µm. The fundamental physical mechanisms that govern the hardness of nanocrystalline materials are discussed.
