The fundamentals of Driverless cars

so far, Google's driverless cars have been running on the road. - more than a kilometer, no accident occurred. What is the reason for this? Does the car have long eyes? To be honest, unmanned driving is safer than driving because the machine is not distracted and will concentrate on driving.

　　1959American Neuroscience expertDavid Hubel(1926-2013experiment with a cat after anesthesia, inserting a miniature electrode in its cerebral cortex to collect the response signal from the neurons (although the signal is very faint). Hubelput a screen in front of the kitten and cast a graphic of different brightness in turn, and let the graphic move slowly. Hubelwant to understand how the visual system of a kitten collects and processes these visual information. Scientists like to talk with facts and not brag about farting.

Hubel It is found that the specific neurons in the cerebral cortex react to the direction of a particular segment, regardless of the position of the segment, where the segment refers to the edge of the object. In other words, a change in the angle of the line will cause different neurons to respond. Hubel also found the reaction process of visual neurons to the depth and color of objects. To this end,Hubel won the 1981 annual Nobel Prize in Medicine.

Geoff Hintonfrom1982began using electronic networks to simulate the human brain, at first,Hintonexperiments are not understood by people and are considered "alternative". However,HintonbelieveHubelThe discovery is correct, since the cortex has a structure, then the use of electronic equipment will certainly be able to simulate, although the accuracy of the simulation is slightly less.

In 2006, Hinton insisted on the brain simulation route finally won. Unmanned cars, with the help of artificial simulation "machine Eye" on the road. Chinese genetically modified food dare not to eat, unmanned cars do not dare to sit, do not want to enter the future world. For this, I am helpless, there is no other way, have to rely on science.
