Why does Watson need so much computing power? I don't know of many NLP algorithms that are so intensive?
Shouldn't IBM start their own search engine if they have algorithms like this? Or conversely, maybe Google should buy them?
The web is not computing.
Earlier quoted context omitted.
The documentary mentioned that Watson does some speech recognition. It attempts to listen to the competitor's answers so that it doesn't give a wrong answer that was already given.
No, it is fed the correct answer by text once the question is completed. They said "listen" in the documentary, but later, in passing, specified what they meant by that. In particular, the demonstrated the active learning when Watson failed to understand a category required dates as answers. After 4 it learned that dates were the type of answer required and got the last question correct. Again, the feeding of the cor…

Because in order to answer a question Watson is really executing hundreds or thousands of different algorithms in parallel to attempt to find candidate answers, and then comparing and building confidence scores for each.
I'd like to see Watson as a web service.
As would I. However, due to the computer resources it takes per question it would be extremely expensive to scale. Watson is made up of a cluster of ninety IBM Power 750 servers (plus additional I/O, network and cluster controller nodes in 10 racks) with a total of 2880 POWER7 processor cores and 16 Terabytes of RAM. Each Power 750 server uses a 3.5 GHz POWER7 eight core processor, with four threads per core. and it…
I assume this is pre-recorded and IBM would have cancelled it if they didn't like the outcome.
It was pre-taped a few weeks ago in line with Jeopardy's usual schedule. There were a number of untelevised practice sessions beforehand against other Jeopardy contestants and wannabes. IBM did their tweaking then and promised that the actual competition rounds would be televised regardless of results.
You'll have the scorn of all the geeks on the internet, which could be interesting lol
