Unified representation of tractography and diffusion-weighted MRI data using sparse multidimensional arrays
NIPS'17: Proceedings of the 31st International Conference on Neural Information Processing SystemsPages 4343–4354Recently, linear formulations and convex optimization methods have been proposed to predict diffusion-weighted Magnetic Resonance Imaging (dMRI) data given estimates of brain connections generated using tractography algorithms. The size of the linear ...

Discovering the Human Connectome
Crucial to understanding how the brain works is connectivity, and the centerpiece of brain connectivity is the connectome, a comprehensive description of how neurons and brain regions are connected. The human brain is a network of extraordinary ...

How information and embodiment shape intelligent information processing
50 years of artificial intelligenceJanuary 2007, Pages 99–111Embodied artificial intelligence is based on the notion that cognition and action emerge from interactions between brain, body and environment. This chapter sketches a set of foundational principles that might be useful for understanding the emergence ("...

On the information theoretic implications of embodiment - principles and methods
50 years of artificial intelligenceJanuary 2007, Pages 76–86Embodied intelligent systems are naturally subject to physical constraints, such as forces and torques (due to gravity and friction), energy requirements for propulsion, and eventual damage and degeneration. But embodiment implies far more than just a ...
