Poster Session Features

• What features did each of you create after the poster session?

• Who did the ideas come from? (could be you)• How good were the resultant features?

Friend Features

• Who managed to find a friend with relevant background expertise?

Friend Features

• What features did your friends suggest?

Cross-validated goodness

• Each of you please list– Your full model’s cross-validated goodness– Your friend model’s cross-validated goodness

• What can we conclude, if anything?

A different approach than Sao Pedro et al. 2013

• Anyone want to summarize that paper’s approach?

• What are the benefits of that paper’s approach?

• Are there any major downsides?

Questions? Comments?

Next week

• Kelley, T. (2001) The Art of Innovation: Lessons in Creativity from IDEO, America’s Leading Design Firm.

• A lot of reading (more than the rest of the semester put together)– You can focus on the parts about brainstorming if you want,

although the whole book is fun and interesting– Heck, you can just skim the parts about brainstorming if you

want

• I assume you’ve all gotten yourself a copy of the book?– If not, e-books are available immediately from Amazon…

Assignment 9

• I was originally thinking that assignment 9 would be a brainstorming assignment

• But I think I’m going to do a different kind of assignment, and we’ll practice brainstorming in class next Monday

Assignment 9

• Write a 1-page essay (longer is also fine)

Assignment 9

• Write a 1-page essay (longer is also fine)– I know, an essay

Assignment 9

• Write a 1-page essay (longer is also fine)– I know, an essay– I’ll be grading based on your thoughts, not

grammar, writing style, writing ability, etc.– Just get your thoughts down on a page– It doesn’t even have to look like an essay. Bulleted

lists are fine (although in that case, make it longer than a page)

Assignment 9

• The essay should be about – Your past experience with brainstorming (if you’ve

never brainstormed, think about any time you’ve come up with ideas with a group of friends or colleagues for a project)

– What went wrong with brainstorming you’ve done in the past?

– Do you think the ideas in this book about how to brainstorm are good in general? What’s good in specific? What’s bad in specific?
