Decision amid uncertainty

Learning to move amid uncertainty.

We studied how subjects learned to make movements against unpredictable perturbations. Twelve healthy human subjects made goal-directed reaching movements in the horizontal plane while holding the handle of a two-joint robotic manipulator. The robot generated viscous force fields that perturbed the limb perpendicular to the desired direction of movement. The amplitude (but not the direction) of...

Business Return in New Orleans: Decision Making Amid Post-Katrina Uncertainty

BACKGROUND Empirical observations on how businesses respond after a major catastrophe are rare, especially for a catastrophe as great as Hurricane Katrina, which hit New Orleans, Louisiana on August 29, 2005. We analyzed repeated telephone surveys of New Orleans businesses conducted in December 2005, June 2006, and October 2007 to understand factors that influenced decisions to re-open amid pos...

Decision making under uncertainty

Decision under Uncertainty

Many new models have been proposed to quantify uncertainty. But usually they don't explain how decisions must be derived. In probability theory, the expected utility model is well established and strongly justified. We show that such expected utility model can be derived in the other models proposed to quantify someone's belief. The justification is based on special bets and some coherence requ...

Decision Making with Uncertainty

In this paper we discuss decision making based on incomplete knowledge. Asthe results of our decisions have always some uncertainties in these cases, we developeda method to measure the advantages brought by those possible solutions of our problem,which makes our decision making problem easier. Our proposal is entirely formulizedwithin the so called classical two valued logic, so it has a solid...
