Turing Test

In this video, we will tell you some useful information about Turing Test.
In recent years, we hear about a lot of different devices with intelligence,
like fridges and electric hovers where they move on their own
and they calculate the quickest way to clean the house.
There is even a coffee machine which knows how you like your coffee.
How do these devices have the intelligence and ability to do all these things
and after which point can we consider their intelligence?
The answer to the question was the Turing test which was created by Alan Turing and named after him.
First of all who is Alan Turing?
Alan Turing was born on 23 of June in 1912 at Paddington in London.
He was professor of mathematics, logic and cryptanalysis.
Turing is widely considered to be the father of computer science and artificial intelligence.
In 1937, he created the “Automatic Machine” which is the current computer,
and it read the punch cards serially which are the current programs.
He worked for the creation of the first two computers, ACE and MARK1.
During the Second World War,Turing was head of Hut 8, the section responsible for German naval cryptanalysis.
He devised a number of techniques for breaking German codes,
and codes of the Enigma machine that could cipher German’s messages.
In 1948, he began writing a chess program for a computer that did not yet exist.
On 7 of June in 1954, while he was experimenting in electrolysis
he ate an apple which had been poisoned with cyanide.
He was found dead on the following day.
The investigation showed that he killed himself but his mother believed it was an accident.
In memory of him, the International Computing Community gives the “Turing award”
to somebody who has created major technical improvements to the Computer Industry.
Here is a video which shows how the Automatic Machine works
and nowadays it's known as turing machine.
Alan Turing devised a test to prove Artificial Intelligence.
In the Turing Test, there are three different rooms. In the first one there is a machine,
in the second one there is a person and in the third there is another person who is the investigator.
The investigator does not know where the machine is and where the person is.
The communication between the investigator and the other two is done through terminals.
The investigator starts to pose questions simultaneously to the others.
The machine and the person give their answers, and the investigator based on those,
tries to understand which is the machine and who is the person.
If the investigator can not separate the two, then we can say that the machine has intelligence.
There is no machine that has passed the Turing Test yet, and may never be possible.
However Turing test is the base to evaluate the artificial intelligent systems.
A machine to be able to pass this test must have some abilities.
It must be able to manage language so that it can communicate and demonstrate its knowledge.
It must think using information to answer questions which will produce conclusions.
It must adapt through learning new situations and find and conclude new models.
The Turing Test avoids the direct physical interaction between the investigator
and the machine, so they created the Total Turing Test.
The "Total Turing test“ a variation of the “Turing test”, adds two further requirements, Computer Vision and Robotics.
In order that the machine is able to pass the test, it must have Computer Vision
to understand subjects, and robotics to manipulate objects.
And here is an example with a robot which has a human face and can answer questions .
In the Turing Test, the benchmark is the human level of intelligence.
The Turing Test must limit the machine’s intelligence to that of a person.
For example, the machine is quicker and more accurate than a person calculating a mathematical problem.
The test limits the human intelligence to solving problems only using symbols.
But how can machines have intelligence? Only by learning!
Here is an example with a machine that chats with people and learns from this process.
Here is another example of chat bots, where two machines have conversation.
When Alan Turing created the Turing Test, he was not able to imagine that the roles of machines and people would be reversed.
Every day millions of people are taking the inverse Turing Test by the machines in order to show that they are people.
These tests are named CAPTCHA.
CAPTCHA means “Completely Automated Public Turing test to tell Computers and Human Apart”.
CAPTCHA is obeying two basic principles. People can easily pass them, and it is almost impossible to create an algorithm that can solve them.
The most known is the “text based CAPTCHA”. In this one, the server chooses a random word,
it converts it to a picture which is showed in the page, and it asks the visitor to write the word that he can see on it.
For the creation of CAPTCHA several techniques are used so as to be more difficult for the machine to pass them.
Some of these techniques use random strings, different fonts for every picture or every character on it.
Complicated patterns and colors in the background and using strikethrough lines and other techniques…
Every day, the users of the Internet face more CAPTCHA tests and that starts to be annoying. So why use CAPTCHA?
The reason of their existence is to cope with the spam and “black hat SEO”.
The spammers want to advertise their products and for that reason they create bots for finding emails or make massive posts for them.
The “black hat SEO” creates links for specific websites, to increase the ranking of those websites in the different search engines.
Technology making better and better. And here is a robot which it shows it...
At some time in future, machines may have intelligence and will be able to compete with the human intelligence!!!
It may do jobs better than peoples and finally be a better creature. But it will never have feelings… And it always be a box!!!
