Google Artificial Intelligence can predict flight delays and cheapest fare

Google will now predict if your flight will be delayed using it's Artificial Intelligence algorithm with 80% accuracy

Flight delays are always frustrating for travelers. Google has launched a new feature on its site, which it says can predict flight delays with over 80 percent accuracy, long before the airlines let anyone know.

The tool is available on the website Google Flights, as well as on Google's Flights app.Google Flights is an online flight booking search service which facilitates the purchase of airline tickets through third party suppliers.Google can help you choose right flight with cheapest rate for your journey. So far Google flight has been a flight search service just like any other service provider, but with the introduction of Artificial Intelligence ,Google flights is going to stand out from others.

Google AI has already a made remarkable achievements in various fields.Recently NASA revealed they use Google AI to detect exoplanets.

How Google AI predict flight delays

An Artificial Intelligence system usually learns by examples. Using historic flight status data, Google's machine learning algorithms can predict some delays even when this information is not available from airlines yet.

"We’re at least 80 per cent confident in the prediction. We still recommend getting to the airport with enough time to spare, but hope this information can manage expectations and prevent surprises," says Google in a blog post.

How to check flight delay
Go to google search bar and type in your flight number. That's all.It will give estimated time of departure and arrival along with other information like terminal,gate etc.. 

Here is the search result for Lufthansa LH 401 New York City to Frankfurt flight on 4th February 2018. You can see that Google predicts Flight may be delayed by DELAYED 1 HR, 50 MINS. Reason for the delay is also included. However google suggests 'confirm flight status on an airport monitor'.

However, these features are currently limited to American, Delta, and United Airlines.Soon google may include other airlines data too to predict  in flight status using Artificial Intelligence algorithm.

NASA uses Artificial intelligence to finds solar system with earth like planet

NASA with the help of Google's Artificial finds a solar system like ours by analyzing data provided by Kepler Space Telescope

NASA's Kepler Space Telescope launched with a mission to spot earth-like planets outside solar system (exoplanets).So far Researchers have used the NASA Kepler Telescope to discover more than 3,000 different exoplanets.

Recently researchers from NASA announced they have achieved some thing new. Using Google's Artificial Intelligence(AI) and data collected by Kepler Telescope scientists have identified a solar system like ours far far away, containing a star and 8 planets revolving it.

The newly-discovered Kepler-90i – a sizzling hot, rocky planet that orbits its star once every 14.4 days.About 30 percent larger than Earth, Kepler-90i is so close to its star that its average surface temperature is believed to exceed 800 degrees Fahrenheit, on par with Mercury. Its outermost planet, Kepler-90h, orbits at a similar distance to its star as Earth does to the Sun.“The Kepler-90 star system is like a mini version of our solar system. You have small planets inside and big planets outside, but everything is scrunched in much closer,” said Vanderburg, a NASA Sagan Postdoctoral Fellow and astronomer at the University of Texas at Austin.

Why Artificial Intelligence?

NASA's Kepler Telescope has been searching alien worlds since 2009.Kepler’s dataset consists of more than 35,000 possible planetary signals. Automated tests, and sometimes human eyes, are used to verify the most promising signals in the data. However, the weakest signals often are missed using these methods.NASA was waiting for the right tool or technology to unearth them.Here comes the tech giant Google's Artificial Intelligence and Neural Network.

How researchers used Gooogle's Artificial Intelligent Neural Network to search earth like planets and solar systems like our's?

Shallue, a senior software engineer with Google’s research team Google AI, came up with the idea to apply a neural network to Kepler data. He became interested in exoplanet discovery after learning that astronomy, like other branches of science, is rapidly being inundated with data as the technology for data collection from space advances.

“In my spare time, I started googling for ‘finding exoplanets with large data sets’ and found out about the Kepler mission and the huge data set available,” said Shallue. "Machine learning really shines in situations where there is so much data that humans can't search it for themselves.”

NASA's Website says,'The discovery came about after Christopher Shallue along with another reasearcher Andrew Vanderburg trained a computer to learn how to identify exoplanets in the light readings recorded by Kepler – the minuscule change in brightness captured when a planet passed in front of, or transited, a star. Inspired by the way neurons connect in the human brain, this artificial “neural network” sifted through Kepler data and found weak transit signals from a previously-missed eighth planet orbiting Kepler-90, in the constellation Draco.'

How Neural Network is trained to identify exoplanets?

A neural network is like our brain. If it is taught with enough examples , it can take decisions thereafter.So, researchers trained the neural network to identify transiting exoplanets using a set of 15,000 previously identified exoplanet data.The network learned it and identified similar data patterns in the huge collection of Kepler data.

In the test set, the neural network identified correct set of exoplanet data with 96% accuracy.After number of testings the researchers directed their model to search for weaker signals in 670 star systems that already had multiple known planets. Their assumption was that multiple-planet systems would be the best places to look for more exoplanets.

Neural network will become more precise as it is fed with more and more data patterns. Shallue and Vanderburg plan to apply their neural network to Kepler’s full set of more than 150,000 stars so that more exoplanets can be sifted out.
