  1. Markov Indecision Processes Harry Q. Bovik, Judy Q. Goldsmith, Q. Andrew Klapper, Michael Q. Littman Journal of Machine Learning Gossip

  2. What’s it all about, Alpha? • Choose inactions • Optimize expected outcomes • Minimize regrets • Mazimize confusion (getting it all together • Accentuate the positve

  3. Definition Let M = <I, I, I, I>, where • I is an indexed set of states, including a distinguished state iC , the state of confusion • I is the set of indecisions • I is the set of inactions The next state is a function of the current state, current indecision, and current inaction. The process ignores all this and chooses a next state via state transgression.

  4. Transgressions • The Markov indEciSion proceSs, or MESS, ends in a state of disbelief. • Associated with each state and inaction is something called the futility level, aka the frustration value. • The agent tries to optimize net fultility over time, usually post-hock. • This is called RETROOPTIMAL POLICY DETERMINATION

  6. APPLICATIONS

  7. Deciding when to purchase airline tickets* Assigning mentors for the doc consortium • The 2000 US Presidential Election

  8. What I really want to tell you about giving a talk…..

  9. Organizing the technical material • What is the problem being solved? • What’s the solution? • How is it new, what does it improve on? • How does it fit into the bigger picture of related work?

  10. Basics of technical presentations • Don’t use it until you’ve defined it • Tell us what you’re gonna tell us; • Tell us; • Tell us what you’ve told us. • Take home message: “This is why you should read my paper”

  11. Slides and posters • Make it readable---eschew fancy backgrounds and small fonts! • Use the visuals to support your verbal presentation; if the audience wanted to read long paragraphs, they’d go directly to the paper!

  12. Verbal presentation • Don’t mumble • Do move around, use varying voice tone • Sound like you think the work is interesting • Respond positively to questions

  13. Most important! • Practice • Practice out loud • Time an out-loud practice talk • Revise to fit the time and practice again • Practice the first 2 minutes and last 2 minutes again

  14. Now you know….
