Deep learning Branch of machine learning Early forms of neural networks were inspired by information processing and distributed communication nodes in biological systems, particularly the human brain. However, current neural networks do not intend to model the brain function of organisms, and are generally seen as low-quality models for that purpose.[6] Importantly, a deep learning process can learn which features to optimally place at which level on its own. Prior to deep learning, machine learning techniques often involved hand-crafted feature engineering to transform the data into a more suitable representation for a classification algorithm to operate on. The word "deep" in "deep learning" refers to the number of layers through which the data is transformed. Deep learning architectures can be constructed with a greedy layer-by-layer method.[11] Deep learning helps to disentangle these abstractions and pick out which features improve performance.[8] Deep learning revolution [edit] Deep neural networks
World of lights in the microcosmos - Research News 06-2010-Topic 6 Television screens are becoming increasingly flatter - some have even become almost as thin as a sheet of paper. Their size takes impressive dimensions, much to the delight of home cinema fans. Cellphones and laptops also have ever brighter and more brilliant displays. All of these developments owe their thanks to miniature light-emitting diodes – LEDs – that beam background lighting into a multitude of devices. However, LED technology does have a disadvantage. To do so, the researchers of IPT developed a process chain with which they can populate large-scale sheets with the necessary microstructures. »It‘s an ultraprecise process,« says Dr. In order to determine if the microstructured master possesses the desired characteristics, it must first be tested based on a few parameters. »The machine can accomplish this task as well,« says Wenzel. »With our ultraprecise machine, we are capable of producing an entire array of systems with background lighting,« says Wenzel.
How to Buy a Cheap 27-Inch Monitor from Korea Crossover is a brand you've probably never heard of before. There are a million 21-inch monitors out there, but around 27 inches the choices start to thin out. Big names take over. If you want anything over 1920x1200 pixels, choices are slim. The rising stars of the monitor world are a group of Korean brands available for import via eBay. The screen is flawless--not a single dead pixel in sight--and after weeks of working, gaming and movie watching, I think the Crossover is the second-best PC upgrade I've ever made, behind a blazing fast SSD. That's part of the dilemma: Korean import monitors are cheap, but the trade-off is risk. The first half of this feature contains my impressions using the Crossover 27Q as my primary monitor for a few months. A Few Months with the Crossover 27Q The Crossover 27Q doesn't look or feel like a cheap $400 monitor. But the Crossover's stand is good out of the box. The screen itself looks every bit as good as one of Apple's Thunderbolt displays.
