Gaussian process data fusion for heterogeneous HRTF datasets

Yuancheng Luo, Dmitry N. Zotkin, Ramani Duraiswami
2013 2013 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics  
We present a Bayesian fusion method based on Gaussian process (GP) modeling of joint spatial-frequency HRTFs over different spherical-measurement grids.  ...  Many laboratories have their own apparatuses for data-collection but few studies have compared their results to a common subject or have modeled inter-dataset variances.  ...  DATA FUSION We first establish notation as follows: For T HRTF datasets, let inputs X = X {1} , . . . , X {T } correspond to observations y = y {1} ; . . . ; y {T } by the dataset pairings Di = X {i} ,  ...

Attention controls multisensory perception via 2 distinct mechanisms at different levels of the cortical hierarchy

Ambra Ferrari, Uta Noppeney, Christopher Summerfield
2021 PLoS Biology  
The current study asks to what extent and how attentional mechanisms can actively control how sensory signals are combined for perceptual inference.  ...  Our results show that distinct neural mechanisms control how signals are combined for perceptual inference at different levels of the cortical hierarchy.  ...  Acknowledgments The authors thank Tim Rohe and Ma ´te ´Aller for sharing custom code for Bayesian modelling.  ...
