Solutions here.
HW #8 due Fri 11/2 to Kay (or her email with subject line "[Math 490]
HW#8 ..." or her mailbox in AH 250 or
her door-box at IH 231) by 3pm:
Proposal for final project.
1. Identify your topic and your thesis statement (see
link).
2. Think about your audience: your classmates, not just me; people in
STEM, not just in your field. Answer two or more of the following questions: Why should your audience care? What do you want them to take away from your project? How can you clarify the benefits of your project to your audience?
3. Specifics: What kinds of audiovisual aids will you be choosing to
use? Your project should have at least one item of visual interest
(picture, simulation, etc.), and at least one item of technical
interest (theorem, algorithm, etc.). Which two or three definitions or
key ideas will you introduce to your audience? What is a good example
(think n=2) that illustrates the main point of your project? Can you
find a story that's related to your topic?
4. Describe the main messages of at least 3 references that you are
using, i.e., what are their thesis statements?
HW#9: textbook problems #12.4, #13.1, #13.3, #14.1. Due on paper to
Kay or Michael by the end of class on Friday 11/9.
Solutions here. Plus read one or
two of the following on technical communication that is relevant to
your final project, and write a two- or three-sentence
summary/analysis of what you took away from your reading
in an email to Kay with subject line: [Math 490] HW#9 reading by [author]...
"How to Talk Mathematics" by Paul Halmos
Doumont's downloadable
booklet on slide design for scientific talks
"Slides
are not all evil" by Jean-luc Doumont.
"How
to give a good 20-minute math talk" by William Ross
"The
Science of Scientific Writing" by Gopen and Swan
"How
to Write Mathematics" by Halmos.
HW#10 due Nov 16 by the end of class: textbook problems #14.2, #15.1.
Solutions here.
Plus this revising exercise: trimming words. Option 1): Take an old email of
yours to someone important that was too long (more than 2-3
paragraphs of 2-3 lines each), and trim it down without losing key
information. You may fictionalize/redact names, etc., for
privacy. Include word counts before and after: the after
count should be no more than 85% of the before count. Option 2):
Revise two slides of a talk, maybe yours or someone else's,
according to the principles that you've learned. This may include
finding or drawing a picture to illustrate the main point of the
slide, or making the wording more efficient to reduce word-wrap. The
result should look something like this
example,
with four slides: two originals and two improved versions
(hand-drawn is fine).
Extra credit opportunity: a book review due after Thanksgiving, based
on a book that will help you with your final project. You can pick the
book in class on Mon 11/12, Wed 11/14, or Fri 11/16. For this extra
credit, you should read (at least) part of the book, summarize its
main points, find a nice quotation from it, and provide a
recommendation of who should read it. Please also return the book
by the final :)
HW#11 preview, due Nov 30: book problems 15.3 and 16.3 due by the end of
class Friday.
Solutions here. Plus: First draft of your final project due by the end
of the week. For a paper, you should have at least 1.5 pages of text (12 pt font; 1 to 1.5
spacing), about half a page outlining the remainder, a figure, and
citations. For a talk, you should have at least 8 finished slides, plus the remainder of the talk
outlined (e.g., headlines only). If you turn your first draft in as hard-copy, I can mark it up with specific
suggestions; if you turn it in electronically, I will reply by email with more
general comments/suggestions. If you'd like a particular kind of
feedback (e.g., if you hand in hard-copy but you only want general
suggestions), please let me know.

NO HW due on December 7. Instead there is Exam 2 in class.
HW#12 preview due 12/12:
Read this
review
of Noble's Algorithms of Oppression,
and write a two sentence summary/analysis.
Revising advice from Stephen B. Heard, The Scientist's Guide to Writing, p. 198ff.
1. Read for self-revision at the time of day that you think least clearly.
2. Change your font to something unfamiliar or strange-looking.
3. Read your draft out loud.
4. Remind yourself to read like a reader, not like the writer.
5. Check for unclear pronoun antecedents: this, that, these,
and those.
6. Does your topic sentence of each paragraph cohere with the rest of the paragraph?
7. Do you have transitions between paragraphs and sections? How are the different topics related?
All final projects are due via email by the final exam time, Friday, Dec. 14 at
7pm (for speakers, this means emailing final slides before 7pm).
Attendance/participation will be graded during the final exam period,
estimated to run from 7pm to 9pm on Dec. 14, in the usual
classroom.
Departures from "traditional" machine learning will be
encouraged for the final project, and you have a choice of paper (3-10
pages), talk (15 minutes), poster (regular size), or webpage (3-6 screens)

Syllabus
This is an advanced course on the mathematics of machine learning, and
some probability/statistics and programming are prerequisites for this course. Machine learning is a growing field at the intersection of probability, statistics, optimization, and computer science, which aims to develop algorithms for making predictions based on data. This course will cover foundational models and mathematics for machine learning, including statistical learning theory and neural networks, with a project component.
Topics: We will be covering most of the topics in Chapters 2, 3, 4, 5,
6, 9, 10, 12, 13, 14, 15, 16, 19, and 20. We will skip most of
Chapters 7, 8, 11, 17, and 18. At the end of the semester, time
permitting, we will cover some of my recent research. The final exam
period will probably be spent on talks by your classmates, so please
plan to be here then.
Why work on your communication skills?
"It usually takes me more than three weeks to prepare a good
impromptu speech."
--Mark Twain
I think that success in your career (any career) depends in part on how well you
communicate your ideas and persuade other people, so I
am giving you a chance to learn and
practice good writing or presenting skills. Some of the homework assignments
will lead up to the final project,
for which you will have a choice of topic (related to the course) and of communication format (paper or
talk). The homework will be graded partly on clarity, brevity, and coherence.
This is a great opportunity to improve your writing or
presenting skills, in order to make your ideas more
clear and persuasive--and to succeed.
"I am sorry I have had to write you such a long letter, but I did
not have time to write you a short one."
--Blaise Pascal
