+  == Introduction ==  
+  
+  === Background ===  
+  The current sequence of courses ([[#ACM116ACM/EE 116]], [[#ACM216ACM 216]], [[#ACM217ACM 217]]/[[#EE164EE 164]]) were first offered in the 200506 academic year following discussions between Emmanuel Candes, Babak Hassibi, Jerry Marsden, Richard Murray and Houman Ohwadi about how to integrate some of the course offerings in ACM and EE, with an eye toward applications in CDS. As a consequence of these changes, EE 162 (Random Processes for Communication and Signal Processing) was eliminated and replaced by [[#ACM116ACM/EE 116]].  
+  
+  There are three drivers for evaluating the course sequence at this time:  
+  * It's been a while since we set this up and it would be good to get together and see what we think about how its been going.  
+  
+  * CDS is about to require [[#ACM116ACM/EE 116]] as part of its PhD requirements (in place of CDS 140b) and this may increase the enrollment in both [[#ACM116ACM/EE 116]] and the followon courses => it would be nice to think through any implications that has.  
+  
+  * As part of the slow ramp up to creating a new PhD program in "systems mathematics and engineering" (or whatever we call the XYZ program), we are planning on a "stochastic systems" sequence that would probably be based on this set of courses.  
+  
+  In addition, in looking through Caltech's current course offerings, it appears that there are several courses in statistics and stochastic systems that might benefit from better integration. These include:  
+  
+  * Courses on statistical modeling and analysis:  
+  ** [[#ACM118ACM/ESE 118]]  Methods in Applied Statistics and Data Analysis  
+  ** [[#Ec122Ec 122]]  Econometrics

+  ** [http://www.cs.caltech.edu/~adamw/courses/286/ CS 286]  Performance Modeling (of computing systems)  
+  
+  * Other courses that may have partial overlap with the main topics in ACM 116/216/217:  
+  ** [[#Ae115Ae 115ab]]  Spacecraft navigation: includes statistical orbit determination problem (batch and sequential Kalman filter implementations)

2018 course offerings
Primary courses in probability and stochastic processes
ACM/EE 116 Introduction to Probability Models. 9 units (315); first term. Prerequisites: Ma 2, Ma 3.This course introduces students to the fundamental concepts, methods, and models of applied probability and stochastic processes. The course is application oriented and focuses on the development of probabilistic thinking and intuitive feel of the subject rather than on a more traditional formal approach based on measure theory. The main goal is to equip science and engineering students with necessary probabilistic tools they can use in future studies and research. Topics covered include sample spaces, events, probabilities of events, discrete and continuous random variables, expectation, variance, correlation, joint and marginal distributions, independence, moment generating functions, law of large numbers, central limit theorem, random vectors and matrices, random graphs, Gaussian vectors, branching, Poisson, and counting processes, general discrete and continuoustimed processes, auto and crosscorrelation functions, stationary processes, power spectral densities.
CMS/ACM/EE 117. Probability and Random Processes. 12 units (309); first term. Prerequisites: ACM 104 and ACM/EE 116. The course will start with a quick reminder on probability spaces, discrete and continuous random variables. It will cover the following core topics: branching processes, Poisson processes, limit theorems, Gaussian variables, vectors, spaces, processes and measures, the Brownian motion, Gaussian learning, game theory and decision theory (finite state space), martingales (concentration, convergence, Doob’s inequalities, optional/optimal stopping, Snell’s envelope), large deviations (introduction, if time permits).
Ma/ACM 144 ab. Probability. 9 units (306); first, second terms. Prerequisites: For 144 a, Ma 108 b is strongly recommended. Overview of measure theory. Random walks and the Strong law of large numbers via the theory of martingales and Markov chains. Characteristic functions and the central limit theorem. Poisson process and Brownian motion. Topics in statistics. Instructors: Tamuz, Ivrii.
ACM 159. Inverse Problems and Data Assimilation. 9 units (306); first term. Prerequisites: Basic differential equations, linear algebra, probability and statistics: ACM 104, ACM/EE 106 ab, ACM/EE 116, ACM/CS 157 or equivalent. Models in applied mathematics often have input parameters that are uncertain; observed data can be used to learn about these parameters and thereby to improve predictive capability. The purpose of the course is to describe the mathematical and algorithmic principles of this area. The topic lies at the intersection of fields including inverse problems, differential equations, machine learning and uncertainty quantification. Applications will be drawn from the physical, biological and data sciences.
ACM 216. Markov Chains, Discrete Stochastic Processes and Applications. 9 units (306); second term. Prerequisite: ACM/EE 116 or equivalent. Stable laws, Markov chains, classification of states, ergodicity, von Neumann ergodic theorem, mixing rate, stationary/equilibrium distributions and convergence of Markov chains, Markov chain Monte Carlo and its applications to scientific computing, Metropolis Hastings algorithm, coupling from the past, martingale theory and discrete time martingales, rare events, law of large deviations, Chernoff bounds.
ACM/EE 217. Advanced Topics in Stochastic Analysis. 9 units (306); third term. Prerequisite: ACM 216 or equivalent. The topic of this course changes from year to year and is expected to cover areas such as stochastic differential equations, stochastic control, statistical estimation and adaptive filtering, empirical processes and large deviation techniques, concentration inequalities and their applications.

Introduction
Background
The current sequence of courses (ACM/EE 116, ACM 216, ACM 217/EE 164) were first offered in the 200506 academic year following discussions between Emmanuel Candes, Babak Hassibi, Jerry Marsden, Richard Murray and Houman Ohwadi about how to integrate some of the course offerings in ACM and EE, with an eye toward applications in CDS. As a consequence of these changes, EE 162 (Random Processes for Communication and Signal Processing) was eliminated and replaced by ACM/EE 116.
There are three drivers for evaluating the course sequence at this time:
 It's been a while since we set this up and it would be good to get together and see what we think about how its been going.
 CDS is about to require ACM/EE 116 as part of its PhD requirements (in place of CDS 140b) and this may increase the enrollment in both ACM/EE 116 and the followon courses => it would be nice to think through any implications that has.
 As part of the slow ramp up to creating a new PhD program in "systems mathematics and engineering" (or whatever we call the XYZ program), we are planning on a "stochastic systems" sequence that would probably be based on this set of courses.
In addition, in looking through Caltech's current course offerings, it appears that there are several courses in statistics and stochastic systems that might benefit from better integration. These include:
 Courses on statistical modeling and analysis:
 ACM/ESE 118  Methods in Applied Statistics and Data Analysis
 Ec 122  Econometrics
 Ma 112  Statistics
 SS 222  Econometrics
 SS 224  Applied Data Analysis for the Social Sciences
 Additional advanced courses (ala ACM 217/EE 164):
 Other courses that may have partial overlap with the main topics in ACM 116/216/217:
 Ae 115ab  Spacecraft navigation: includes statistical orbit determination problem (batch and sequential Kalman filter implementations)
 CDS 110b  Control systems: includes noise as disturbances as random processes, Kalman filtering and sensor fusion
 CDS270  Stochastic System Analysis and Bayesian Updating (special topics course): includes Bayesian modeling, Markov Chain stochastic simulation, Bayesian sequential estimation, Kalman filtering
 CS 1012  Active Learning and Optimized Information Gathering: includes Markov decision processes, Bayesian search
 CS 286  Performance Modeling (of computing systems): includes probability theory, Markov chains, Queueing theory, heavytailed distributions
