+ - Google's Neural Networks See Even Better ->

Submitted by mikejuk
mikejuk (1801200) writes "Google is becoming as well known for neural networks as the other kind. The annual ImageNet large-scale visual recognition challenge, ILSRVC, is the a testing ground for all manner of computer vision techniques, but recently it has been dominated by convolutional neural networks which are trained to recognize objects simply by being shown lots of examples in photographs.
In 2012 there was a big jump in accuracy when a deep convolutional net designed by Alex Krizhevsky, Ilya Sutskever and Geoffrey E. Hinton proved for the first time that neural networks really did work if you had enough data and enough computing power. This is the neural network that Google has used in its photo search algorithm and, of course, the team they hired to implement it.
This year's competition also brought a jump in performance. Google's GoogLeNet,, yes Goog-le-net, named in honour of LeNet created by Yan LeCun, won the classification and detection challenge while doubling the quality over last year's results. This year the GoogLeNet scored 44% mean average precision compared to the best last year of 23%.
In simple recognition tasks neural nets are as good as humans so a more difficult task has now become the focus of attention. Not only do the nets have to recognize photo of a single object — dog, cat etc., they now have to recognize multiple objects in a photo, a dog with a hat on say, and localize the objects by drawing bounding boxes. This is much harder and tens of thousands of CPU cores were used to train GoogLeNet.
Once nets can recognize individual object and where they are they are well on the road to scene analysis and description — a long-time goal of computer vision systems. A robot with GoogLeNet could with the right higher level software see what was about them."

To me, I don't see anything interesting about the 6 and 6+ that would make it worth jumping from an iPhone 5S or even an iPhone 5.

MUCH BETTER BATTERY LIFE = 6+ battery is over twice as large as iPhone 5s battery, from 1,440 mAh to 2,915 mAh. While some might say "battery life will be the same because of the larger screen" it's been shown in iPad's that is not true, devices like the Mini have an enormous battery life despite the 8" screen and only a 4,490 mAh battery. If the 6+ can get just half the battery life of the Mini that will be a huge improvement from the battery life of the 5s. Apple is already reporting the 6+ will provide several hours more battery life than the 5s.
LARGER SCREEN = no dispute there
FINGERPRINT = 5s had fingerprint but 5 did not. That will make it much easier to unlock the phone and make iTunes payments
NFC = if mobile payments work out like they're saying this could be the best feature of the iPhone 6. It could mean never needing to get out your wallet and never having to worry about your credit card or identity stolen.
OPTICAL IMAGE STABILIZATION = would help a lot when recording videos, optical image stabilization is usually much better than digital stabilization.
BETTER CAMERA = anyone that has bought a cheap camera knows big megapixel numbers do not mean a good camera. The iPhone 6 is still "only" 8 megapixels but adds a new iSight sensor and Focus Pixels technology for focusing faster.
MOTION CO-PROCESSOR = anyone that uses their phone while working out would like this. The A8 chip includes the new M8 motion co-processor which recognizes data from gyroscopes, accelerometers and compasses.

+ - The First Sophisticated Domestic Robot - The Dyson 360 Eye ->

Submitted by mikejuk
mikejuk (1801200) writes "Yes it's a vacuum cleaner! But you knew it would be. The real question is why has it taken so long to make a sophisticated robot to do the menial job of cleaning the floor. The typical Roomba style robot vac runs around at random bumping into things and getting tangled in anything it can find. It is an endearing little machine and once you have owned one the idea of not having one is unthinkable but... it is still a little dim, even for the menial job of cleaning the floor.
Enter the Dyson 360 Eye which was launched last week. This is an upmarket cleaner. Not only does it have a radial root cyclone suction machine it also has, as it's name suggests, 360 degree vision.
A 360 degree panoramic lens lets an infrared sensor see all around. The sensors work in conjunction with a video camera to place objects in the scene. As it moves around it builds a model that is accurate to 5mm. It uses SLAM — Simultaneous Localization And Mapping — which is one mark of an advanced robot. In short — this Dyson knows where it is.
And what is the advantage of this?
Simple — the robot doesn't bump into things and it can clean systematically, which is much more satisfying for a human observer at the very least.
Add to this radial root cyclone suction, tank track to avoid slipping or getting stuck and an iOS and Android app to control it and you have a very desirable floor cleaning robot — but is it overkill? At more than $1000 it will be available early next year and you can pre-order now even if you only want it to hack. See it in action in the video."

The solution is simple: load them up with tranquilizers/sedatives and stack 'em in like cordwood. ;)

A seemingly good idea that will fall apart as soon as someone overdoses on sedatives and their next-of-kin sue. Good luck with persuading a judge that some getout clause in a 3pt font prevents any liability attaching...

You're confusing the cost of legitimate operations with the cost of searching the key space. You don't want legit users to bear too much cost since everyone ends up paying that over and over, but you do want the cost of searching to be high since that's not something that people should be doing.

The trek itself was trivial compared to summiting Everest but the visuals were just a lot more impressive.

You don't need such fancy protective gear when doing Everest, which is just cold and lacking in oxygen, not outright chemically hostile and hot as hell. (Some volcanoes are even worse. The ones that spew fluorine gas (or hydrofluoric acid) are just awful...)

I assume they mean computer related. In high school I was labeled a "hacker" because I went into the bios and disabled the hard drive of the computers in the computer lab. Even the "it guy" couldn't figure out how I "removed the hard drives without opening the cases" because the message just said "hard drive not found" so he thought I had somehow physically removed the hard drives. Since this was pre-Internet days there wants much help for error messages so he couldn't just google it to find the answer

It's called JPEG2000, uses wavelet transformations instead of discrete cosine transformations that JPEG uses and has been around since over a decade ago. No one uses it.

You're wrong there. It's used quite a lot in high-capacity digital image storage. Libraries, that sort of thing. You might have the space and time to waste on using standard JPEG and you might not care too much about the compression artefacts, but libraries really do care. (A billion high-resolution images is only a medium-sized library...)

Exactly this. Requiring professional drivers to have additional training and the proper insurance is a good thing. I can't believe Uber and Lyft have been able to get away with it in the US since normal car insurance in the US does not cover passengers if they are paying for the ride. All it takes is one idiot with poor coverage to hit your car while you're driving around paying passengers and you're screwed, you'll have garnished wages for life and you'll lose anything of value so the courts can pay the medical expenses of your passenger
