I have completed the coding but need to tune the covariance matrices P, Q & R for error,process and measurement covariance.Below are the most common reasons: This site uses cookies to improve performance by remembering that you are logged in when you go from page to page.To provide access without cookies would require the site to create a new session for every page you visit, which slows the system down to an unacceptable level. I found an algorithm for updating inverse of a matrix after small norm update using regression interpretation of inverse of covariance matrix, so I assumed something similar should exist for eigenvectors. I have 8k features and millions of datapoints, so covariance is approximate. Gradient update depends on eigenvalues of certain covariance matrix, and this covariance matrix changes at each step A naive approach is to use the eigenvalue solution of your matrix $A(t)$ as the initial guess of an iterative eigensolver for matrix $A(t \delta t)$. New iterative methods for solutions of the eigenproblem.
