Twitter announces first algorithmic bias bounty challenge – ZDNet

Published

 on


Twitter has announced its first algorithmic bias bounty challenge, offering cash prices ranging from $500 to $3,500 for those who can help the social media giant identify a range of issues. 

After significant backlash last year, the company admitted in May that its automatic cropping algorithm repeatedly cropped out Black faces in favor of White ones. It also favored men over women, according to research from Twitter. Multiple Twitter users proved this fact using pictures of themselves or of famous figures, like former President Barack Obama

Rumman Chowdhury, director of Twitter META, explained that the company decided to change the algorithm and admitted that companies like Twitter often “find out about unintended ethical harms once they’ve already reached the public.”

On Friday, Chowdhury and Twitter META product manager Jutta Williams unveiled the algorithmic bias bounty competition, which they said was part of this year’s DEF CON AI Village. 

“In May, we shared our approach to identifying bias in our saliency algorithm (also known as our image cropping algorithm), and we made our code available for others to reproduce our work. We want to take this work a step further by inviting and incentivizing the community to help identify potential harms of this algorithm beyond what we identified ourselves,” the two said. 

In creating the program, they were inspired by how the research and hacker communities helped the security field establish best practices for identifying and mitigating vulnerabilities in order to protect the public. 

They said Twitter wanted to build out a similar community but one focused on machine learning ethics that will help the company “identify a broader range of issues than we would be able to on our own.” 

“With this challenge we aim to set a precedent at Twitter, and in the industry, for proactive and collective identification of algorithmic harms,” Chowdhury and Williams wrote. 

“For this challenge, we are re-sharing our saliency model and the code used to generate a crop of an image given a predicted maximally salient point and asking participants to build their own  assessment. Successful entries will consider both quantitative and qualitative methods in their approach.” 

There is a submission page on HackerOne where people can find more information, the rubric used to score each entry and details on how to enter. The entries will be judged by Ariel Herbert-Voss, Matt Mitchell, Peiter “Mudge” Zatko, and Patrick Hall.

The first place winner will get $3,500, the second place winner gets $1,000 and third place gets $500. There will also be $1,000 rewards for most innovative and most generalizable. Winners of the competition will be announced at the DEF CON AI Village workshop on August 8.  

Williams told ZDNet that other than learning more about the photo cropping feature, she is expecting to learn what people think “harm” entails.  

“As a product manager, I endeavor to put myself in the shoes of people who use or are affected by our products to understand what a word like that means. Traditionally, we hear from people already looking at algorithmic bias — and I’m expecting that we’ll hear from a much broader community of people who will share a lot of perspective on what harm means to them,” Williams said. 

“Rumman floated the idea with me and our CTO after a conversation with the AI Village organizers — it takes a pretty risk-tolerant company to go first on something like this. Twitter leadership was willing — enthusiastic even. We didn’t have a lot of time to make the deadline for DEFCON, so the two of us got right into brainstorming how to scope something that we could release within the few weeks we had to make a go/no-go decision.”  

She added that the competition will make Twitter much wiser about how the next event should run and be instructive in making it easier for participants and more inclusive.  

The company is also hoping to learn more about how their technology may need to be immediately corrected, Williams explained, and more about how they can better prevent harm. The team will gain a better understanding of how to test and assess algorithms for biases, Williams said. 

Williams noted that there are many unknowns in the emerging field of study on machine learning bias and few programs actively address algorithmic risks. 

“I have hope we’ll have a few more unknowns that we can start working on solving.  Most importantly, maybe, we’re going to learn about working with this community, ways to better measure and classify harms, what it takes to validate reports, ways to mitigate and/or prevent new harms in the future — all of which we can share back to the community,” Williams said.  

“This wasn’t run for our benefit alone — I wouldn’t personally have put the sweat equity into it if it weren’t for the goal of ultimate transparency.”

iQOO Neo 6 VS Poco F4: We compare the specs, both will SURPRISE – HT Tech

Published

 on


iQOO Neo 6 vs Poco F4: Both these Snapdragon 870 smartphones under Rs. 30000 are tempting, but which is better?

iQOO Neo 6 or Poco F4? Of late, the smartphone space under Rs. 30000 has seen two strong offerings from these fairly young brands. iQOO, which is a subdivision of Vivo, announced the iQOO Neo 6 last month as its most affordable offering with the Snapdragon 870 chipset, promising better gaming experiences and an overall midrange collection of specifications. The iQOO Neo 6 comes with a decent set of cameras too and is currently one of the most exciting phones money can buy at this price.

However, Poco has the same idea and it manages to offer its Poco F4 at a much lower price. Launched just hours ago, the Poco F4 has almost the same kind of spec sheet as the iQOO Neo 6, save for minor differences. In essence, this is a rival to the iQOO Neo 6 and if you are wanting to spend that much money on a performance smartphone for around Rs. 30000, it does add to the confusion. After all, both look good on paper.

Since we have reviewed both of the smartphones lately, we put both of these against each other and here is what we think.

Poco F4 vs iQOO Neo 6 Design

While both the smartphones have distinct designs to flaunt, it is the Poco F4 that pulls the lead with its glass rear panel. The Poco F4 feels better built, especially with its fit and finish. That’s not to say the iQOO Neo 6 is poorly built but the phone’s plastic unibody design is not as desirable. 

Poco F4 vs iQOO Neo 6 Display

Honestly, both these smartphones are equal when it comes to the display specs. Both phones have a 6.67-inch FHD+ E4 AMOLED display with a refresh rate of 120Hz and higher touch sample rates. No in-display fingerprint scanner on either of these.

Poco F4 vs iQOO Neo 6 Performance

The same Snapdragon 870 chip powers both the Poco F4 and iQOO Neo 6. Hence, it is your pick. The Snapdragon 870 is a stable chipset that delivers high on performance, especially in terms of thermal stability and throttling. You will be able to play all the high-end games such as COD Mobile and Apex Legends Mobile at high graphics settings with ease.

Poco F4 vs iQOO Neo 6 Software

This is where your preference matters. Poco uses Xiaomi’s MIUI 13 interface based on Android 12 whereas the iQOO neo 6 uses Vivo’s FunTouch OS 12 based on Android 12. Both custom skins are full of customisation features and pre-loaded apps. Both brands promise three years of OS updates.

Poco F4 vs iQOO Neo 6 Cameras

Both the Poco F4 and iQOO neo 6 feature a triple camera setup on the rear – a 64MP main camera, an 8MP ultrawide camera, and a 2MP macro camera. The Poco F4 has a 16MP selfie camera while the iQOO Neo 6 has a 32MP camera

Poco F4 vs iQOO Neo 6 Battery

The iQOO Neo 6 on paper has a bigger 4700mAh battery compared to the 4500mAh battery on the Poco F4. The iQOO Neo 6 offers a 80W fast charging solution while the Poco F4 has a 67W fast charging. 

Poco F4 vs iQOO Neo 6 Price

This is where the Poco F4 takes a mega lead. Starting at 27,999 for the base 6GB/128GB storage, the F4 is cheaper. The 8GB/128GB variant costs Rs. 29,999 whereas the 12GB/256GB variant comes with a price of Rs. 33,999. The iQOO Neo 6 starts at Rs. 29,999 for the base variant with 8GB/128GB variant.

Technical issue temporarily stops Canadian Forces Snowbirds from flight performances

Published

 on

OTTAWA — The Department of National Defence says the Canadian Forces Snowbirds will be unable to fly in planned air shows and flypasts until a technical issue is resolved.

That means performances next Wednesday in the Moncton, N.B., area will be cancelled while technicians work to get the team back in the air for Canada Day in Ottawa.

The department says in a news release the issue relates to a device that sets the timing for the deployment of the parachute during the ejection sequence.

It says during routine maintenance, technicians discovered the tool may not be calibrated accurately and the parachutes will now be retested and repacked to ensure proper timing for their activation in the event of an emergency.

It’s not known how long it will take to fix the issue, but the release says the Royal Canadian Air Force is working with experts and a third-party aviation contractor to get the team back in the air as soon as it is safe to do so.

It adds Air Force experts have determined there is no link between the 2020 crash in Kamloops, B.C., that killed Capt. Jenn Casey — which occurred after a bird flew into an engine — and the current issue with the parachute device.

This report by The Canadian Press was first published June 24, 2022.

Vergecast: M2 MacBook Pro review, Solana's crypto phone, and this week's tech news – The Verge

Published

 on


Every Friday, The Verge publishes our flagship podcast, The Vergecast, where Verge editor-in-chief Nilay Patel, editor-at-large David Pierce, and managing editor Alex Cranz discuss the week in tech news with the reporters and editors covering the biggest stories.

On today’s episode, Nilay and Alex chat with Verge senior reviewer Monica Chin about her review of Apple’s 13-inch MacBook Pro with the M2 chip. Though the chassis is still the same as the previous model, the changes that come with the new M2 processor are significant. Apple has yet to release their redesigned M2 MacBook Air, so should you wait before buying the Pro? Monica shares her thoughts.

For the rest of the show, we change up the crew. Alex and David lead the discussion with Verge deputy editor Dan Seifert about the state of streaming — with Netflix cutting 300 jobs after losing subscribers and an overall lack of innovation and new features within all the streaming apps.

In the final segment, we focus on the gadget coverage we’re known for. We found out more about Nothing’s first phone, were introduced to Solana’s crypto phone, and Dan is starting to enjoy using the Microsoft Surface Duo 2 six months after its launch.

There’s a whole lot more in between all of that, so listen here or in your preferred podcast player for the full show.
