WebDec 1, 2011 · The proposed Bayesian regression self-training method for updating the parameters of an unscented Kalman filter decoder uses the decoder's output to periodically update its neuronal tuning model in a Bayesian linear regression, and significantly improved the accuracy of offline reconstructions.
WebHowever, applications of CNNs for single-neuron decoding are still scarce and require further validation. In this study, a CNN architecture was designed via Bayesian optimization and was applied to decode different grip types from the activity of single neurons of the posterior parietal cortex of macaque (area V6A). WebJan 1, 2008 · Discussion. This paper has described a multivariate Bayesian (MVB) scheme to decode neuroimages. This scheme resolves the ill-posed many-to-one mapping, from voxels or data features to a target variable, using a parametric empirical Bayesian model with covariance hyperpriors. This model is inverted using expectation maximisation to …
