Artificial Intelligence- The Spread!

Apple’s Siri and other smartphone voice-recognition systems are an everyday example of a digital assistant that exhibits artificial intelligence. Many people start their mornings by asking Alexa for the weather forecast or the latest news. A device that houses the software can also play music from your favorite playlists, keep a shopping list, order takeout food, answer trivia questions, send voice messages and even run “smart” home controls like thermostats. Alexa is a form of artificial intelligence, or AI for short. But this digital personal assistant is just one of many AI systems that have have become a part of modern life.

Another well-known one is AlphaGo. It's an AI system designed by Google that recently beat a human champion, Lee Sedol, at the strategy board game Go.

Training AI systems to respond to problems with human-like intelligence — and learn from their mistakes — can take months, or even years.

Computers can’t understand language as it is spoken by people. So AI researchers must find a way to help humans communicate with computers. The technology used to get computers to “understand” human speech or text is known as natural language processing. By natural language, computer scientists refer to the way people naturally talk or write.To teach an AI system a task like understanding a sentence in English or responding to a person’s last move in a board game, scientists need to feed it lots of examples. To train AlphaGo, Google had to show it 30 million Go moves ( OMG!) that people had made while playing the game. Then AlphaGo used what it learned by analyzing those plays (such as what moves won and which lost) as it played against different versions of itself.

During this practice, the program became so skilled and clever that it came up with novel moves — ( now this is giving me goosebumps :-P) that one has never seen in games between people.

AI doctors
Artificial intelligence can help doctors make quick and efficient use of new and complex findings to improve patient care. Scientists generate new information about diseases and treatments each and every day. According to one study, 10.5 million scientific papers were published worldwide in 2017 . Can doctors keep them updated ?  A little difficult but computers can.

Take Watson. IBM built this computer for one purpose - to answer people’s questions. Watson uses the same natural-language-processing approach. In 2011, Watson demonstrated just how good it was when it beat two flesh-and-blood champions answering questions on the TV show Jeopardy! That win earned Watson more than $77,000.

Clearly, Watson was a champ at answering trivia. Now IBM has given this quiz whiz a more serious job: helping doctors find the right treatments for cancer patients. In its new role, the program is known as Watson for Oncology. (Oncology refers to the study or treatment of cancer.) Doctors at Memorial Sloan Kettering Cancer Center in New York City trained the program.

 Now a physician can ask this Watson system to recommend a treatment for a particular patient. Before it answers, the AI assistant quickly pulls up the patient’s medical history and lab reports. It also can review notes from doctors that are written in plain English, it can tap into data on other Memorial Sloan Kettering patients  and how well their treatments worked. That’s thousands of cancer patients a year! Watson for Oncology can even sift through millions of pages of medical research to learn what other researchers have been reporting about a particular drug’s safety or how well it works. In the end, a doctor may choose not to follow Watson for Oncology’s recommendation. When that happens, the software will log that information too.

Learning complex math concepts can frustrate some students, especially if their teachers are too busy to give them much extra attention. To help bridge that gap, more than 2,500 U.S. schools are using AI-powered software called Mathia. (BTW until last year, it was called Cognitive Tutor.) The system helps teach a host of math concepts to students from grades 6 through 11. Mathia is different from ordinary math software. Most math problems can be solved in more than one way. Mathia can recognize each student's learning style. Then it will try to serve up customized clues  - ones especially suited to that individual.

My perception is robots can increase mechanical ability but EQ wise I still am not convinced!  They might just help you become the best version of yourself - That is only if you would want and if you would allow it to !  On the whole I feel AI better just guide us or just entertain us and they better be kept in that status-box itself.
