“Stochastic Processes: Data Analysis and Computer Simulation”
This is the third round of the course as the self-paced format. The original version of the course was produced and operated from March 30,
Instructors: Ryoichi Yamamoto & John J. Molina
See "Meet the Course Staff" section for more details.
Course Description
The motion of falling leaves or small particles diffusing in a fluid is highly stochastic in nature. Therefore, such motions must be modeled as stochastic processes, for which exact predictions are no longer possible. This is in stark contrast to the deterministic motion of planets and stars, which can be perfectly predicted using celestial mechanics.
This course is an introduction to stochastic processes through numerical simulations, with a focus on the proper data analysis needed to interpret the results. We will use the Jupyter (iPython) notebook as our programming environment. It is freely available for Windows, Mac, and Linux through the Anaconda Python Distribution.
The students will first learn the basic theories of stochastic processes. Then, they will use these theories to develop their own python codes to perform numerical simulations of small particles diffusing in a fluid. Finally, they will analyze the simulation data according to the theories presented at the beginning of course.
At the end of the course, we will analyze the dynamical data of more complicated systems, such as financial markets or meteorological data, using the basic theory of stochastic processes.
What you'll learn
- Basic Python programming
- Basic theories of stochastic processes
- Simulation methods for a Brownian particle
- Application: analysis of financial data
Prerequisites
In addition to the knowledge of introductory physics, basic knowledge of linear algebra, calculus (differential and integral), and partial differential equations must be mastered beforehand.
Time commitment
2-3 hours per week
Lectures
Each course will be provided with short Lecture Videos by the instructor, Ryoichi Yamamoto (in all weeks) and John J. Molina (in week 6) along with a set of short Problems related to the contents of the Lecture Videos. By watching the videos and answering the Problems, we hope that all participants will gain practical skills to perform numerical simulations and conduct proper data analysis needed to interpret the results. We also hope that the participants will get some deep insights from real-world data, such as financial markets or meteorological data, using proper knowledge which will be obtained through the course.

Discussion
You are invited to participate in the Discussion forum (See Forum Guidelines here) to share ideas and ask questions to peers relating to each of the course’s contents. We hope this opportunity will lead to fruitful exchanges and discussion.
