Bayes-Optimal Entropy Pursuit for Active Choice-Based Preference Learning

no code implementations24 Feb 2017 Stephen N. Pallone, Peter I. Frazier, Shane G. Henderson

Under certain noise assumptions, we show that the Bayes-optimal policy for maximally reducing entropy of the posterior distribution of this linear classifier is a greedy policy, and that this policy achieves a linear lower bound when alternatives can be constructed from the continuum.

Probabilistic Bisection Converges Almost as Quickly as Stochastic Approximation

no code implementations12 Dec 2016 Peter I. Frazier, Shane G. Henderson, Rolf Waeber

The probabilistic bisection algorithm (PBA) solves a class of stochastic root-finding problems in one dimension by successively updating a prior belief on the location of the root based on noisy responses to queries at chosen points.
