This page keeps track of proposed changes to CDS courses that would be implemented in 2014-15 and future academic years.  In the pages below, insertions are marked {{insert|in blue}} and deletions are {{delete|in red and stroked out}}.

'''Background''': With the establishment of the new CMS PhD program, we are trying to better align the CDS program with the structure of the CMS program and also update our course structure to better serve other options that make use of CDS courses.

=== CMS course requirements ===

* Core requirements: 7 common courses taken by all CMS students (first year)
* Depth requirement: 3 courses in a given area (e.g., Feedback & control, Inference & statistics, Information systems, Networked systems, Optimization, Uncertainty quantification)
* Breadth requirement: 3 courses from mathematics, science, engineering, or economics

* Depth: 45 units in CDS or other advanced courses in systems theory, dynamical systems, and/or applied mathematics.

Topics include: Bayesian updating of system models based on system time-history data, including Markov Chain Monte Carlo techniques; Bayesian model class selection with a recent information-theoretic interpretation that shows why it automatically gives a quantitative Ockham’s razor; stochastic simulation methods for the output of stochastic dynamical systems subject to stochastic inputs, including Subset Simulation for calculating small “failure” probabilities; and Bayes filters for sequential estimation of system states and model parameters, that generalize the Kalman filter to nonlinear dynamical systems.
