Test Shows Big Data Text Analysis Inconsistent, Inaccurate 60

DillyTonto writes The "state of the art" in big-data (text) analysis turns out to use a method of categorizing words and documents that, when tested, offered different results for the same data 20% of the time and was flat wrong another 10%, according to researchers at Northwestern. The Researchers offered a more accurate method, but only as an example of how to use community detection algorithms to improve on the leading method (LDA). Meanwhile, a certain percentage of answers from all those big data installations will continue to be flat wrong until they're re-run, which will make them wrong in a different way.

I think reusable orbital entry vehicles

The shuttle was very impressive in that they made it work, but in accomplishing the goal of low cost access to space ? Not so much.

Mars landers, and the half a dozen other probes scattered on missions throughout the solar system might be something to brag about

Viking was 1976, nice thing for the Bi-Centenial if your young and Bi Curious you might want to google that. But it's nearly 40 years gone.

What they haven't done is make space more accessible, arguably Arianespace. Orbital Sciences and Space-X have done considerably more in moving humanity towards being a spacefaring species.

I'd love to agree with you but NASA hasn't been anything to brag about for maybe 30 years now. The upcoming Space Launch System is looking to be a horrible boondoggle.

At what point would you say criticism is warranted ?

Or at what point would you say it's fair, to ask just what is the point of a Mars mission ? That we should drain resources from just about everything else we do in space to pursue it ?

That's because google doesn't sell information to people, that Verizon, ATT, Comcast don't sell information about you, that's because there aren't businesses that collect detailed information about you and sell them to anyone who looks.

Oh wait, there are all those things.

Be pleased, it takes a special kind of person to think speaking in pig latin makes their conversation private.

All email, social media, banking and consumer purchases take place over SSL connections, and have for a long time. So the "party line" stuff is a non-starter.

So you use gmail, yahoo mail, hotmail, or corporate mail ? You don't think the providers don't or can't parse that ? It's not your mail it's theirs after all.

You don't think the credit card companies don't record and share information with the credit reporting agencies ?

Who. Who else has the budget AND the physical proximity to the bulk of the fiber (which runs through the US) to do a "full take" of what people do online.

Oh I don't know, maybe the people selling you your net access ?

Comment Software patents (Score 3, Insightful) 134

the last time I checked, [GIMP] still lacked the support for color matching that would make it viable for creating images that were print-ready.

Have the patents on practical methods of color matching expired yet? If not, then it's impossible for free software to support proper color matching.

Dell would be stupid to put Ubuntu on touchscreens. For those, they should use Android itself.

Window management in Android OS is designed to display a single application maximized. This works for 4 to 8 inch screens of phones and tablets, not so much for 13 inch or larger screens of laptops, where people expect to view applications side by side. Change this behavior and your customers will lose access to Google Play Store.
