Scientists in the US are developing artificial intelligence (AI) systems that could help robots assist soldiers in the battlefield in future.
For the research, published in the journal Science Advances, the team looked at soldier brain activity during specific tasks for ways to incorporate AI teaming to dynamically complete tasks.
According to Jean Vettel, a senior neuroscientist at the Army Research Laboratory (ARL) in the US, technologies that can predict states and behaviours of the individual soldier may help create a more optimised team.
The work between ARL and the University at Buffalo is looking at ways the dynamics and architecture of the human brain may be coordinated to predict such behaviours and consequently optimize team performance.
“In military operations, soldiers perform multiple tasks at once. They’re analysing information from multiple sources, navigating environments while simultaneously assessing threats, sharing situational awareness, and communicating with a distributed team,” said Vettel.
“This requires soldiers to constantly switch among these tasks, which means that the brain is also rapidly shifting among the different brain regions needed for these different tasks,” he said.
“If we can use brain data in the moment to indicate what task they’re doing, AI could dynamically respond and adapt to assist the Soldier in completing the task,” he added.
To achieve this future capability, the researchers first sought to understand how the brain coordinates its different regions while executing a particular task. They used a computational approach to understand how this may be characterised to inform the behavioural prediction.
To complete the study, researchers mapped how different regions of the brain were connected to one another in 30 different people via tracts of tissue called white matter.
Scientists converted these maps into computational models of each subject’s brain, and used computers to simulate what would happen when a single region of a person’s brain was stimulated.
They then used a mathematical framework, which they developed, to measure how brain activity became synchronised across various cognitive systems in the simulations.
“While the work has been deployed on individual brains of a finite brain structure, it would be very interesting to see if coordination of Soldiers and autonomous systems may also be described with this method, too,” said Javier Garcia, an ARL neuroscientist.
“Much how the brain coordinates regions that carry out specific functions, you can think of how this method may describe coordinated teams of individuals and autonomous systems of varied skills work together to complete a mission,” Garcia said.
WhatsApp’s 5 upcoming features that will make the app more interesting
WhatsApp is the most popular instant messaging app in the world. Over the years, WhatsApp has continued to add new and interesting features without compromising on ease-of-use. The Facebook-owned firm is now working on more new features that are set to make the app more interesting and convenient.
Dark Mode is one of the most anticipated features on WhatsApp. The feature has been often spotted in the beta versions of the app. The Dark Mode inverts the colours to help reduce strain on eyes, especially after sunset. Google has already added the feature on some of its key applications including Chrome browser and YouTube. Apple introduced system-wide Dark Mode with iOS 13. WhatsApp is also expected to add the feature sooner or later.
Quick Edit Media
WhatsApp is working on a “quick edit media” feature. Spotted in the recent beta version of the app, the feature allows users to make changes to media files sent or received. Note the feature is different from the existing edit tools that WhatsApp provides. According to WABetainfo, a website that monitors the latest changes to WhatsApp, users can edit the media in-chat and share directly.
More forwarded info
In a bid to fight fake news and misinformation on its platform, WhatsApp last year added a “forwarded” label on messages that have been forwarded by the sender. The company is now going to improve this feature by adding a “frequently forwarded” label. Whatsapp is also working on a new feature that will tell how many times a message has been forwarded. The feature is expected to be part of the info section which tells when the message was delivered and when it was read.
WhatsApp is making it easier to add a new contact through QR codes. Expected to launch very soon, WhatsApp’s QR code is said to be very similar to nametags on Instagram. Each user will receive a unique QR code which can be shared with others. WhatsApp already uses QR code for WhatsApp Web that mirrors the phone version.
Hide muted status
Similar to Facebook’s unfollow, WhatsApp’s ‘hide muted status’ the feature doesn’t completely block a contact just hide from the Status feed. Right now, even if you mute a status, a faded version appears at the bottom of the feed. The company is reportedly improving the feature by removing the muted Status feed altogether.
For me, the story is above my character: Ayushmann Khurrana
Ayushmann Khurrana says for him more than his character, the story of a film and the message it leaves behind, is a bigger priority.
The 34-year-old actor said he does not mind playing an immoral character if the plot does justice with the fate of the part.
“I would love to do a variety of scripts and characters. If the story resonates with me, I would definitely do a character which is not moral.
“But at the same time, it has to be a message in the end, against a character or maybe whatever that character needs to learn eventually. For me the story matters above my character. I am obsessed with good stories,” Ayushmann told PTI.
The actor, who has made a mark for himself courtesy his unique choice of films, believes every performer has “different aspirations”.
“It also really depends on what your priorities are. Some scripts are to prove your acting abilities, some scripts are there to have a certain social responsibility and as I said everyone has different aspirations in life, so, being progressive and regressive is a very subjective thing,” he added.
Ayushmann has struck a chord with the audience, but the actor said there is no formula to maintain the connect.
“Anybody can go wrong. Whatever is relevant right now may be irrelevant five years from now. Our industry is ever-changing and our society is ever-evolving so I cannot be cocky and pompous enough to say that I have a great script sense. I hope my gut supports me in future as well,” he said.
His latest Article 15 has turned out to be the second-biggest opener of his career after Badhaai Ho! and the actor is elated with the overwhelming response from both the audience and critics.
The Anubhav Sinha-directed film, which released on June 28, has earned over Rs 70 crore worldwide.
“Commercial success is really important but at the same time, it has to be a mix of both critical and commercial acclaim. Credibility is the key for any artiste.”
Ayushmann will be seen next in Dream Girl and Bala – releasing this year while his other film Gulabo Sitabo with Shoojit Sircar will come out next year.
Oppo K3 with pop-up front camera to launch in India on July 19
Oppo is set to launch its new mid-range smartphone, Oppo K3 in India on July 19. The company has now revealed that it is partnering with Amazon to launch the device. The e-commerce site has already started taking registrations of interest on its website with the Notify Me button on the device page.
Oppo will reveal the pricing and availability details on the launch date with the disclosure of a list of introductory offers. The device will be made available in Purple and Black gradient colour options.
To recall, Oppo K3 has already been launched in China and is priced at Yuan 1,599 (approximately Rs 16,000) for the 6GB RAM/64GB storage variant, Yuan 1,899 (approximately Rs 19,000) for the 6GB RAM/128GB storage variant and Yuan 2,299 (approximately Rs 23,000) for the 8GB RAM/256GB storage variant.
