TheDrive for the Future
Driverless ears
Professor Sebastian Thrun, director of the StanfordArtificial Intelligence Laboratory, wants to cut the number of ears on planet earth by 50%.
He said: "It’s a huge waste of money and resources to do so—we use ears about 3% of the time. "
Professor Thrun is a leader in the field of driverlessCars and has built two robotic vehiclescalled Stanley and Junior.
The cars have no human driver and no remote control system—everything from sensors to navigation is handled by an onboard computer.
They were both entered into theDARPA、GrandChallenge—a race for autonomous vehicles. Stanley won in 2004 and Junior took second place in 2007.
But the ultimate goal is to create a world where self - aware vehicles can drive passengers around without hitting pedestrians or bumping into other vehicles.
"To be able to understand the environment as deep as humans do is the holy grail of artificial intelligence. "
"It’s a huge amount of work to make computers understand what is the behaviour of the two people on the right, both waiting at an intersection—will they walk or not It is a really hard question. "
Perfect missions
Researchers at Stanford are trying to program helicopters to fly perfect missions every time including loops.
Imagine, for example, a search and rescue chopper that can descend into a narrow canyon countless times without its rotors ever touching the edges.
Andrew Ng, an associate professor in theComputer ScienceDepartment, said it would be very difficult to write software to make a helicopter early out stunts in the air.
Instead, researchers asked a expert human pilot to demonstrate the stunts. The computer learned from the demonstrations how to fly by itself.
It is called apprenticeship learning—the computer figures out what the human pilot is trying to do and then uses algorithms to correct or perfect the operations.
Professor Ng said:" The accelerometers of the helicopter will feel the force of the wind pushing the helicopter aside and what the helicopter has learned to do is how to adjust the controls to move itself back onto the desired flight path. \
What can be inferred from the passage
A、It is easy for pilots to do the stunts when operating helicopters in the air.
B、It is easy for helicopters to descend into a narrow canyon to do rescue work.
C、It is difficult to design software which enables a helicopter to do stunts.
D、There is no such software that enables a helicopter to do stunts.
