    Define: Artificial intelligence- the branch of computer science that deal with writing computer programs that can solve problems creatively; "workers in AI hope to imitate or duplicate intelligence in computers and robots" Turing test- The Turing test is a proposal for a test of a machine's ability to demonstrate intelligence. It proceeds as follows: a human judge engages in a natural language conversation with one human and one machine, each of which tries to appear human. All participants are placed in isolated locations. Why is a Jeopardy-playing computer considered such a huge advance in AI? Because Jeopardy represents a next generation on AI that advancements in artificial intelligence and natural language processing that overcome the formidable challenge of conveying the same information in many different ways. The supercomputer owes that significance to its ability to deliver more than calculations and documents. This kind of ability makes this machine more equipped than any before it to systematize "thoughts" and converse.

IBM supercomputer wins first Jeopardy dust up - Computerworld - 1 views

    Explain how Watson can mimic human intelligence. Watson mimics human intelligence by going through the same process humans do in order to find an answer. Watsons can comprehend clues and pieces of information, analyze the information that is given, and come up with an answer to the problem. Explain the ways that computers can rival a human in answering questions. Computers are systematic machines. Humans, can also be, but in a less precise manner. Thus, computers that are given the same amount of information, and have access to a lot of background knowledge can possibly rival humans in answering questions because of the systems' advantage of sorting out pieces of information and analyzing it digitally. Humans depends on their brains, and not knowing whether they really do, or how much they analyze the data correctly or not. A computer's digital system can come up with a number of possibilities precisely and thus calculate the best conclusion to the question. Explain the ways AI can impact personal lives. With the help of AI, human needed jobs such as diagnosing problems and illness, self-service centers, and information center tasks can be given to the AIs. Also, this can enhance humans personal lives by offering the humans an extra helping hand, that isn't as emotional as humans, and can be just as effective as well as useful, albeit the cost will be very high. Why was Jeopardy a good challenge? Jeopardy is a good challenge because of the structure of the Jeopardy game itself. The game itself only provides sly clues, riddles mixed with sarcasm and irony. Humans can detect such facts in the clues, but for a machine, as well as the system to be able to recognize these clues as well as reading in between the words to understand the meaning for an answer is a challenge. The system would have to be taught the same way humans are taught to notice such abnormalities of the hints. This is harder to teach an AI since it doesn't follow the same path of instruction

Kibot the robot entertains kids, spies on them - 0 views

    AI Rock Summary Answer here :)
  •  
    Korean children, already fast becoming a robot-friendly lot, have a new companion in Kibot, a monkey-faced bot that can read fairy tales, sing songs, take pictures, and make video calls via a display embedded in its tummy. It is like a robot that will keep children accompany, Kibot, which runs on a rechargeable battery and is manufactured by iRiver, has plenty of other tricks up its sensor-enabled sleeves, too. It responds to gestures, like pats, by turning and pleasantly saying, "It feels good." When it encounters an obstacle, it can change direction to avoid it. It can take pictures and record and play back customized voices. It even serves as a language tutor for Korean and English. About the only things it doesn't do, seemingly, are scratch its head and swing from branch to branch.

Unmanned aerial warfare: Flight of the drones | The Economist - 7 views

    On September 30th, a missile strike launched from a UAV killed Anwar al-Awlaki, al-Qaeda's most effective propagandist. This was an example of how the UAV are changing today's combat. These babies are equipped with sophisticated sensors and carry Hellfire missiles and laser-guided bombs. There may not be a man in the cockpit, but each Reaper UAV requires more than 180 people to keep it flying. A pilot is always at the controls from a ground control unit and another officer operates its sensors and cameras. UAV have become the weapon of choice over the past decade. Theres not a month that passes without reports that an al-Qaeda or Taliban leader has been killed by UAVs. There are more hours flown by America's UAS than by its manned fighter jets and more pilots are being trained to fly them than their manned equivalents. The frequency of drone stikes on terrorists in Pakistan has rose from one every 40 days to one every four days under Obama's admin. The UAV's ability to loiter for hours, minutely observe human activities while transmitting full motion video to its ground crews and can strike with pinpoint accuracy has made it the essential weapon in America's war on terrorism. Drones come in many different shapes and sizes. Predators and Reapers are the larger and more popular ones. Some are micro sized devices that imitate a bird used for eavesdropping or a mid sized plane that can be hand launched by soldiers to tell them what is happening over the hill. The medium sized UAVs would be able to defend airspace against enemy intrusion to attacking enemy air defenses. The largest UAV would operate as airborne warning and control, aerial refueling tankers, lift transports and long range bombers. The next generation of drones will also have AI, which allows them to shoot to kill. The UAS are used for "dull, dirty, dangerous, difficult or different" tasks. These tasks include surveillance missions requiring time and a degree of persistence that crews of

    manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

    Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.
