  • The first quiz has been postponed to Monday, Feb. 11.

Lectures, Suggested Readings, and Suggested Problems

  • Lecture 1: Introduction (1/4/01)
    (ppt)
    (pdf)

  • Lecture 2: Sufficient Statistics and Exponential Families (1/7/01)
    (ppt)
    (pdf) (Poor, pp. 158-160, 164; Hero, pp. 24-30; some lecture
    examples taken from pp. 30-33 of Srinath)
    Suggested problems: Hero, Sec. 3.5, #5, #6 (parts a and b only)

  • Lecture 3: Introduction to Bayesian Estimation (1/9/01)
    (ppt)
    (pdf) (Poor, pp. 142-147)
    (Poor, pp. 142-147; Hero pp.
    32-38)

  • Lecture 4: Examples of Bayesian Estimation (1/11/01)
    (whiteboard)
    (Poor, pp. 147-152, pay particular attention to Example IV.B.2;
    Hero, pp. 38-42)
    Suggested problems: Poor, Sec. IV.F: #1, #7

  • Lecture 5: More Examples and Properties
    of Bayesian Estimation
    (1/14/01)
    (whiteboard)
    (Hero, pp. 42-46)
    Suggested problem: Poor, Sec. IV. F: #25 (parts a and b only)
    Highly suggested problem: Try to derive the CME,
    CmE, and MAP estimators
    on pp. 43-44 of Hero (good practice with erf functions; you may need to do
    integration by parts)

  • Lecture 6: The Orthogonality Principle in MMSE Estimation (1/16/01)
    (ppt)
    (pdf)
    (Poor, pp. 221-229; Hero, pp. 82-96)
    Suggested problems:
    Three interesting MMSE problems with solutions
    (PDF)
    , Scan of an old UIUC exam problem
    (This one is interesting since it shows how the orthogonality principle
    is useful for things beyond computing linear MMSE. Here, you compute a
    quadratic MMSE!)

  • Lecture 7: Examples of Linear and Nonlinear MMSE Estimation (1/18/01)
  • Lecture 8: Nonrandom Parameter Estimation (1/23/01)
    (ppt)
    (pdf)
    (Poor, pp. 173-185; the discussion on p. 179 and continuing on to the
    top of p. 180 is particularly enlightening; Hero, pp. 51-60, pp. 70-76)

  • Lecture 9: The Cramer-Rao Bound (1/25/01)
    (ppt)
    (pdf)
    (Poor, pp. 167-173, pp. 185-186; Hero, pp. 60-70)
    Suggested problems: Poor, Sec. IV. F: #15, #25 (now try parts c and d)

  • Lecture 10: Estimation Under Additive Gaussian Noise (a.k.a. Least
    Squares Solutions) (1/28/01)
    (ppt)
    (pdf)
    (Poor, pp. 155-157)

  • Lecture 11: Examples with Non-Gaussian Data, Part I
  • Lecture 12: Examples with Non-Gaussian Data, Part II
  • Lecture 13:”The” Expectation-Maximization Algorithm
    (Basic Formulation and Simple Example) (2/4/02)
    (ppt)
    (pdf)
    )

Other Goodies

  • Volkan gave a presentation on estimation theory in Jim McClellan’s
    research group. He let me post his
    slides and a related
    short
    paper
    with related proofs.
    Volkan did a great job; it’s
    a nice distillation of some of the material in Ch. 4 of Poor. Enjoy!
