Besides applications on problems like digital image and speech recognition, machine learning (ML) methods are also used to predict complicated patterns in earthquake activity, say researchers.

It can be used to hone predictions of seismic activity, identify earthquake centres, characterise different types of seismic waves and distinguish seismic activity from other kinds of ground “noise”, according to a team of seismologists.


More seismologists are using the method, driven by “the increasing size of seismic data sets, improvements in computational power, new algorithms and architecture and the availability of easy-to-use open source machine learning frameworks,” said the team, including Karianne Bergen from the Harvard University in the USA, in a paper published in the journal Seismological Research Letters.

These methods, called deep neural networks, can explore the complex relationships between input data and their predicted output. For instance, one kind of deep neural network can be used to develop ground motion models for natural and induced earthquakes in Oklahoma, Kansas and Texas.

The unusual nature of the growing number of earthquakes caused by petroleum wastewater disposal in the region makes it essential to predict ground motion for future earthquakes and to possibly mitigate their impact, the researchers noted.

The techniques can also be used to better identify earthquake aftershocks, volcanic seismic activity, monitor tectonic tremor, locate earthquake’s origin and distinguish small earthquakes from other seismic “noise”, they said. (IANS)

The world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

Heinz has just rolled out a new product that the condiment company says is the "biggest innovation in sauce since the packet itself." Earlier this month, the world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.

Swiss tennis ace Roger Federer, is recovering from a right-knee surgery he underwent last month.

Swiss tennis ace Roger Federer, who is recovering from a right-knee surgery he underwent last month, said on Sunday that it was a difficult process to decide whether to undergo a third right-knee surgery after having two last year. But following Wimbledon, where he was "really unhappy" with his performance in reaching the quarterfinals, Federer opted to go through with it.

Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.

"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.

Cleopatra, was regarded as a great beauty, to preserve her skin, she took her daily bath in donkey milk. Besides, Hippocrates, the father of medicine, prescribed donkey milk for various diseases including fever, wounds, etc. To add to these benefits, donkey milk has four times the amount of Vitamin C than cow's milk has. So, it's no secret that donkey milk is a powerhouse of nutrients for both the skin and body.

Used for Anti-Ageing and Healing
The milk contains essential fatty acids that work as powerful anti-ageing and healing properties. These fatty acids blur the wrinkles on the skin and help to regenerate damaged skin. Plus, donkey milk also contains anti-bacterial properties which are effective in healing skin irritation and redness.
