Selected publications

Where we developed a family of fMRI image-computable encoding models for high-dimensional structured feature spaces.

Where we elaborated image decoding from brain activity as a statistical problem where local image sample variance reflected brain representations.

Where we analyzed the concept of functional hierarchy in the context of predictive model based on deep neural networks.
