A constrained HMM-based approach to the estimation of perceptual switching dynamics in pigeons

Autor: Klaus Pawelzik, Jens R. Otterpohl, Frank Emmert-Streib

Publikováno v: Neurocomputing. :1495-1501

We describe a method for the analysis of behavioural data from experiments on perception of bistable stimuli in pigeons. The approach is based on a Hidden Markov Model (HMM) with additional linear factorial constraints for which a modified Baum–Wel

We propose a framework for investigation of the modulation of neural coding/decoding by the availability of prior information on the stimulus statistics. In particular, we describe a novel iterative decoding scheme for a population code that is based

Baum-Welch Learning in Discrete Hidden Markov Models with Linear Factorial Constraints

Autor: Jens R. Otterpohl

Publikováno v: Artificial Neural Networks — ICANN 2002 ISBN: 9783540440741

Here, I introduce a transformation-based method for extending the Baum-Welch algorithm to the training of discrete Hidden Markov Models subject to constraints on the parameters. A class of certain linear factorial constraints is described and shown t

Extracting the dynamics of perceptual switching from 'noisy' behaviour: an application of hidden Markov modelling to pecking data from pigeons

Autor: Klaus Pawelzik, Frank Emmert-Streib, John-Dylan Haynes, G. Vetter, Jens R. Otterpohl

Publikováno v: Journal of physiology, Paris. 94(5-6)

When studying animal perception, one normally has the chance of localizing perceptual events in time, that is via behavioural responses time-locked to the stimuli. With multistable stimuli, however, perceptual changes occur despite stationary stimula
