Stochastic Processes

Graduate-level course at UofT and a core research interest. Probability theory applied to systems that evolve randomly over time.

Level: Graduate-level coursework · core research focus

Topics covered

  • Markov chains (discrete and continuous time), stationary distributions
  • Brownian motion and Wiener processes
  • Poisson processes and renewal theory
  • Martingales and optional stopping
  • Itô calculus (introductory)

Why it matters

ML relies on stochastic processes throughout: Markov decision processes (RL), stochastic gradient descent, diffusion models, probabilistic graphical models. Statistics and Physics (statistical mechanics, diffusion, Langevin dynamics) are deeply connected to this field.
