Beta-negative binomial process and poisson factor analysis
(Journal of Machine Learning Research, 2012-01-01)
© Copyright 2012 by the authors. A beta-negative binomial (BNB) process is proposed, leading to a beta-gamma-Poisson process, which may be viewed as a "multiscoop" generalization of the beta-Bernoulli process. The BNB process ...
Multichannel electrophysiological spike sorting via joint dictionary learning and mixture modeling
(IEEE Transactions on Biomedical Engineering, 2014-01-01)
We propose a methodology for joint feature learning and clustering of multichannel extracellular electrophysiological data, across multiple recording periods for action potential detection and classification (sorting). Our ...
Lognormal and gamma mixed negative binomial regression
(Proceedings of the 29th International Conference on Machine Learning, ICML 2012, 2012-10-10)
In regression analysis of counts, a lack of simple and efficient algorithms for posterior computation has made Bayesian approaches appear unattractive and thus underdeveloped. We propose a lognormal and gamma mixed negative ...
