How to Speak, Again

Let's watch the first 2.5 minutes

• Again, again, and again...
• Video

The opening is amazing!

• Well... He did a much better job than I do.

Build Audiences' Mental Model

Take care of all types audiences

• Experts - everything in this domain is trivial to them
• Students - have some expertise, but not yet matured
• Outsiders - CS undergraduates seeking for advisors
• Big bosses - randomly comes in and out

Audiences are essentially state machines

• States
  • (N)ormal, (E)xciting, D(elighted), (C)onfused, (B)oring, (S)leeping, (L)eaving + (K)nowledge Learned
• Transitions
  • Your slides and words
  • Same words, different transitions for different audiences

Rules of Thumb

Tell a story

• Refer to “How to speak”!
• My invited talk at Chinasoft'22
  • I prepared this talk in a rush (~3 hours)

Link the slides (and titles)

• Tree structure of presentation

Reduce dependencies

• The “least assumption” principle

(Reflect these ideas on the state machine model)

Rules of Lint Warning (1)

Text blocks

• To read, or not to read?

Rules of Lint Warning (2)

Formulas

• Exception: Just showing “there is a formula”

Rules of Lint Warning (3)

Algorithms

• $\le$ 5 lines, OK; otherwise, not OK

Rules of Lint Warning (4)

Experimental results (tables, figures, etc.)

• Always deliver messages (opinions)
• “Improved the SOTA by XX%” is meaningless to most of the audiences—So what?
