Comment What a PhD really is (Score 1) 260

A PhD is about science, not money. With a little bit of luck, you'll be in for a startup project, but otherwise, there is no big money making in science.

On the other hand, it's going to be very interesting. When you write your thesis, you will learn something about yourself: how you can cope with frustration, and how you can do stuff that you though you would never be able to do.

But it's all like professional sports, only a few make it to the top.

Comment a similar study... (Score 1) 979

...was performed in the speech community, and it yielded somewhat incompatible results.

http://www.asru2009.org/uploadedimages/talk/rkm_talk.pdf

They gathered year predictions on milestones like "a majority of mobile phones can translate conversations" from 127 researchers from the speech community and compared them to those of the same studiy performed 6 years ago and 12 years ago. The funny part is that the averages slide with time, as if the future was near, but unreachable. Also, "never" was a possible answers, and it often showed up with a majority of votes.

From the presentation:
* The future appears to be no nearer than it was previously!
* The level of scepticism has remained remarkably stable, but pessimism (realism?) seems to have increased

When the event of interest is rare, one can report F-score (or F-measure), which is the harmonic mean between recall and precision. Recall is the proportion of cases that you have found in the population in regard of the actual number of cases, precision is the proportion of the cases that you have found in regard to the number of cases that you believe to have spotted. In other words: Recall = #(right) / #(truth) Precision = #(right) / #(hypothesis) F-score = 2 * Precision * Recall / (Precision + Recall) There are variants to adjust between recall and precision: http://en.wikipedia.org/wiki/F1_score.

Comment I saw those guys at a conference (Score 1) 83

I saw a presentation at SLT'08 (http://slt2008.org/Papers/viewpapers.asp?papernum=1191) about that voice web. Contrary to what slashdot readers seem to think, this is not an extension of the current www. They want to start over with speech only (input and output). It is designed so that people who can't read can use it, and they don't need the latest smartphone, just a regular phone. URLs would be replaced by phone numbers that you would dial. Then you would be able to listen to whatever "podcast" which would give you other numbers to dial. There is a big cultural difference with the www. They also intend to do speech-controlled basic navigation. However, they didn't give many details about the kind of technology involved, nor how to handle basic navigation problems like the equivalent of scrolling through a page or how to manage bookmarks, mark already visited sites and "download" stuff.
