A Method for Inferring Label Sampling Mechanisms in Semi-Supervised Learning
Inferring Label Sampling Mechanisms Semi-Supervised Learning
2015/8/21
We consider the situation in semi-supervised learning, where the “label sampling” mechanism stochastically depends on the true response (as well as potentially on the features). We suggest a method of...

Due to lack of knowledge:
Missing mechanisms (ignored “too small" or “too fast" or
“unimportant" processes)
Unresolved scales (not represented in models)
Model uncertainties
Truthful mechanisms for two-range-values variant of unrelated scheduling
Truthful mechanism Approximation algorithm Scheduling
2012/11/30
In this paper, we consider a restricted variant of the scheduling problem, where the machines are the strategic players. For this multi-parameter mechanism design problem, the only known truthful mech...
Randomized Truthful Mechanisms for Scheduling Unrelated Machines
Randomized Truthful Unrelated Machines
2012/12/3
In this paper, we consider randomized truthful mechanisms for scheduling tasks to unrelated machines, where each machine is controlled by a sel痵h agent. Some previous work on this topic focused on a s...
