Comment Weighting of ensembles (Score 2, Funny) 58

by reginaldo (#29277101) Attached to: Collaborative Filtering and Rise of Ensembles
One of the difficulties of ensemble development is weighting the logic that is being develeped. For instance, one of the problems we deal with at my job is matching incoming text to it's cleaned value. We have a list of approved words ['happy', 'sad', 'angry', 'sleepy'], and a text input of 'hap'. We need to determine which valid word 'hap' should match. Some rules I can think of for properly matching are:

1.)Length of input compared to cleaned word.
2.)Number of nonpositional letter matches.
3.)Number of positional letter matches.

Depending on how rules are weighted determines what the answer will be (either sad or happy). I know at my job this weighting process requires very careful politicking. :D

Verizon Sued After Tech Punches Customer In Face 493

Posted by samzenpus from the can-you-hit-me-now dept.
suraj.sun writes "A Verizon customer filed a lawsuit after the tech the company sent out got a little punchy. Instead of fixing the customer's problem, the tech allegedly hit him in the face. The New York Post says the tech attacked the customer after he asked to see some ID before allowing access to the apartment. From the article, '"You want to know my name? Here's my name," Benjamin snarled, slapping his ID card into Isakson's face, according to Isakson's account of the December 2008 confrontation. "The guy essentially snapped. He cold-cocked me, hit me two or three solid shots to the head while my hands were down," said Isakson, a limo driver. He said the pounding bloodied his face and broke his glasses. But things got uglier, Isakson said, when Benjamin squeezed him around the neck and pressed him up against the wall. "He's prepared to kill me," Isakson said. "That's all I could think of." The customer broke free and ran away. The Verizon tech then chased the customer until he was subdued by a neighbor who was an off-duty cop.'"

Production of Boeing 787 Dreamliner Delayed Again 334

Posted by timothy from the was-just-a-dream dept.
Hugh Pickens writes "Boeing has discovered microscopic wrinkles in the skin of the 787's fuselage and has ordered Italian supplier Alenia Aeronautica to halt production of fuselage sections at a factory in Italy. 'In two areas on the fuselage, the structure doesn't have the long-term strength that we want,' says Boeing spokeswoman Lori Gunter. To repair the wrinkles, additional layers of carbon composite material are being added to a 787 at the South Carolina factory and twenty-two other planes must also be patched. Production of the 787 has been fraught with problems with ill-fitting parts, casting doubt on Boeing's strategy of relying on overseas suppliers to build big sections of the aircraft before assembling them at its facilities near Seattle. The 787, built for fuel efficiency from lightweight carbon composite parts, is a priority for Boeing as it struggles with dwindling orders amid the global recession. Customers had been expecting the first of the new jets in the first quarter of 2010 — nearly two years earlier than they will be delivered. The delays have cost Boeing credibility and billions of dollars in anticipated expenses and penalties. Orders for 72 planes have been canceled already this year, although Boeing still has confirmed orders for over 800 aircraft."

improve that 12 mpg to 18 mpg and now you need to replace a 30 mpg with a 180 MPG car (the EPA calculates the carbon-cost of an electric vehicle using our mix of power source to be roughly 120 mpg) to match the fuel savings.

Maybe the government could help. They could maybe give an incentive to people with old, inefficient cars to be used toward purchase of new efficient cars. Some sort of "cash for clunkers" type deal. Just a thought.

Outlook Inertia the Main Factor Holding Business From Google Apps 394

Posted by Soulskill from the safety-blanket dept.
Meshach writes "There's an interesting article in PC World claiming that the major factor preventing businesses from transferring their communication interface from Outlook to Google Apps is employees' unwillingness to give up a tool that's so familiar. Basically, Google is underestimating how attached businesses and their workers are to Office and Outlook in particular. Quoting: 'Google has found out that, yes, many companies are happy to ditch Exchange for Gmail if it means saving money and eliminating the grief of maintaining Exchange in-house. However, and maybe to a degree unexpected by Google, it also discovered that many companies consider it a deal-breaker to lose the functionality that the Outlook-Exchange combo provides, thanks to the deep links that exist between this client-server tandem.'"
