PPT-The M/EEG inverse problem and solutions

Gareth R Barnes Format The inverse problem Choice of prior knowledge in some popular algorithms Why the solution is important Volume currents Magnetic field Electrical potential difference EEG. Newtons method for computing least squares In this problem we will prove that if we use Newtons method solve the least s quares optimization problem then we only need one iteration to converge to a Find the Hessian of the cost function 1 Answer As and re-reference .
