AI

• Is [how we think] humans think the best guide to building a computer application?– maybe not. Review history of chess programs.

• Are human applications the best guide to creating applications?– maybe not. The data we have available now is much

more than ever before and visualizations more elaborate than anything that could have been done previously…

Farm Journal

• http://www.agweb.com/ – Check out the harvest results maps (with

comments)

Presentations

• Prepare!– materials that will help you and– help your audience

• Your enthusiasm is the most important factor.

• Devise questions / activities for audience.

Thoughts

• Preparing PowerPoint or something else can be more important than the result. Does help combat stage fright!

• Ensures: – organization– coverage– some concepts really require a visual!– some (but not most) text should be quoted exactly.

• Can be overdone and can work to simplify content.

Posting

• read Tufte's comments on problems with PowerPoint: http://chronicle.com/article/Teach-Naked-Effort-Strips/47398/ and other places– note Challenger issue concerned the proper

presentation of data!• put together problems and temperature

• read http://chronicle.com/article/Teach-Naked-Effort-Strips/47398/

But…

• Repeat: preparing is better than not preparing and

• some/many concepts need visuals

• (and a presentation tool does help the speaker)

Google documents

advantage

• of 'being in the cloud'. Can edit anywhere

disadvantages

• requires being online

Let's try it!

Prezi

• Tool used by Jackie• my lectures for the CQI class.

• Let's try it.

Advantages: • different! Made me re-think my talks.• Can move around. Incorporate videos.• ?

HTML

• Some students do this.

Do something!

• Prepare

• Practice

• Devise ways to involve audience

• If you are interested in your topic, we (the audience) will be.

Language challenges / Talk topics

• Speech recognition. Issues of limits on speech and role of training– transcription– understanding

• Text to text translation. Also issues of scope of language and how accurate it needs to be

• language learning

Posting / Talk possibility

computer use of different alphabets

• Unicode

• ?

captcha• Devise to distinguish humans from 'bots to

prevent large-scale operations such as sending files.

• Opposite of Turing Test???

New two part captcha

• used for scanning of [old] printed documents.• One of two clues is produced by the company:

they know the answer and one is something to be digitized.

• if the user gets the known one correct, then they accept the translation of the other as valid (and do the operation).

• Successful at performing cloud-sourced digitalization of large quantity of text.– posting opportunity: find out more

Duolingo approach

• Background captcha• New challenge: translation of documents.• Solution: provide free lessons plus opportunity to

translate and rate translations. – the translation is part of the lessons. But how can

learners do translation? Answer: assumption is that we do know native language and can judge a statement in English.

• Demonstrate my Spanish lessons.– show email responses to 1 "feedback" and "question"

Suggestion

• Try duolingo.com

• Assess what is going on?– what is database? what is algorithm? what is

going on in audio test?– compare to?

• any other type of drill• any other type of lessons

Ethics

• Do computer professionals need to make ethical judgments in their work?

• What ethical issues have emerged in class?

Homework

• Prepare talk if it is your turn.• Post proposal if you haven't done so.

• Postings
