Putting Bayes to sleep

چکیده
partition specialists We craft a prior on all partition specialists for which Bayes is both • fast: collapses to O(M) time per trial, O(M) space • good: regret close to information-theoretic lower bound Bayes for specialists crash course A specialist may or may not issue a prediction [FSSW97]. Prediction P(y|m) only available for awake m ∈W. Key insight: complete specialists to full models [CV09]: P(y|m) := P(y) for all asleep m / ∈W. circular! With prior P(m) on specialists, the Bayesian predictive distribution P(y) = ∑ m∈W P(y|m)P(m) + ∑ m/ ∈W P(y)P(m)

Accuracy of pattern detection methods in the performance of golf putting.
The authors present a comparison of the classification accuracy of 5 pattern detection methods in the performance of golf putting. The detection of the position of the golf club was performed using a computer vision technique followed by the estimation algorithm Darwinian particle swarm optimization to obtain a kinematical model of each trial. The estimated parameters of the models were subsequ...
متن کاملA Note on the Consistency of Bayes Factors for Testing Point Null versus Nonparametric Alternatives
When testing a point null hypothesis versus an alternative that is vaguely speci ed, a Bayesian test usually proceeds by putting a non-parametric prior on the alternative and then computing a Bayes factor based on the observations. This paper addresses the question of consistency, that is, whether the Bayes factor is correctly indicative of the null or the alternative as the sample size increas...

متن کاملGeneration of Folk Song Melodies using Bayes Transforms
The paper introduces the ‘Bayes transform’, a mathematical procedure for putting data into a hierarchical representation. Applicable to any type of data, the procedure yields interesting results when applied to sequences. In this case, the representation obtained implicitly models the repetition hierarchy of the source. There are then natural applications to music. Derivation of Bayes transform...
