Face recognition with temporal invariance: A 3D aging model
The variation caused by aging has not received adequate attention compared with pose, lighting, and expression variations. Aging is a complex process that affects both the 3D shap...

Robust real-time 3D time-of-flight based gesture navigation
: Contactless Human-Machine-Interfaces (HMIs) are an important issue in various applications where a haptic interaction with an input device is not possible or not appropriate. New...

Hardness of Minimizing and Learning DNF Expressions
We study the problem of finding the minimum size DNF formula for a function f : {0, 1}d → {0, 1} given its truth table. We show that unless NP ⊆ DTIME(npoly(log n) ), there i...

On the Hardness of Being Truthful
The central problem in computational mechanism design is the tension between incentive compatibility and computational ef ciency. We establish the rst significant approximability ...

Lower Bounds for Noisy Wireless Networks using Sampling Algorithms
We show a tight lower bound of Ω(N log log N) on the number of transmissions required to compute several functions (including the parity function and the majority function) in a...
