Twitter invites researchers and hackers to industry's first algorithmic bias competition – Republic World

Published

 on


On Friday, July 30, 2021, Twitter announced a competition for hackers and computer researchers to detect and identify biases in the platform’s image-cropping algorithm. The winners of the competition will receive cash prizes from $500 to $3,500 and will get a chance to present their work at a workshop at DEF CON in August. The aim of the competition is to find potential harms of the image-cropping algorithm and rectify them. 

Twitter launches the industry’s first algorithmic bias bounty competition 

Back in May 2021, Twitter shared their approach to identify bias in its saliency algorithm, which is also known as the image-cropping algorithm. With the recent competition announcement, Twitter wants to invite and incentivise users, researchers and professionals from the community to discover and identify the harms of the algorithm. Twitter also hosted a conversation on their audio-based feature called Spaces on July 30, 2021, to discuss the challenge. The challenge comes after a group of researchers found Twitter’s algorithm to exclude Black people and men.

Twitter also mentions in an official blog post that “We’re 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.” Adding to it, Twitter mentions that it aims to set a precedent in the industry for proactive and collective identification of algorithmic harms. To apply, one can go to the application portal on HackerOne. To take part in the challenge, applicants must go through all the terms and conditions and legal disclaimer given on the application page. One must have a HackerOne account in order to participate in the Twitter algorithmic bias bounty competition.

‘Genshin Impact’ Sumeru Gift Codes For Free Primogems, 3.0 Character Banners, Release Date – Forbes

Published

 on


At long, long last, Genshin Impact just wrapped up its new 3.0 special program, revealing a whole lot of new information about the new region, the new element, Dendro, new characters and of course, there are free goodies if you hung out and wached the stream. Or even if you didn’t, I have them right here.

We’ll just get these out of the way first, here are the three gift codes for free primogems and other materials that you can redeem here. These ones are only good for 24 hours, I believe, so you better hurry.

  • 8ANCKTWYVRD5 – 100 Primogems and 10 Mystic Ore
  • EA7VKTFHU9VR – 100 Primogems and 5 Hero’s Wit
  • KT7DKSFGCRWD – 100 Primogems and 50,000 Mora

Past that, the most pressing information is probably the release date for Genshin Impact’s Sumeru update, which is August 24, 2022.

We also were told about the first two character banners for 3.0, which will include three total Sumeru characters with only one five star. Those are:

  • Phase 1 – Tighnari (5 star), Zhongli (5 star), Collei (4 star)
  • Phase 2 – Ganyu (5 star), Kokomi (5 star), Dori (4 star)

While other Sumeru characters were shown or teased onscreen, it will be deeper into the 3.0 patch series before we get to those, which is not unexpected, given that’s how Inazuma worked, and we ended up getting new Inazuma characters for essentially an entire year. And we’re probably still not done.

Sumeru is probably going to end up being the most significant addition to the game to date, because unlike Inazuma, it’s not just a new region, it also has an entirely new element being added to the game for the first time, Dendro. While Dendro has cropped up here and there among a few enemy types, this is the first time we as players can wield it ourselves, and these new characters will be our first introduction to the concept. Like all the elements, you can probably have attack/defense/support focused teammates using the element, and we’ll have to spend some time digging deep into all the new characters to find out exactly how best to use them in their new roles with this new elemental type supporting your team.

Genshin Impact continues to generate massive amounts of revenue, and I have to imagine the Sumeru region is going to boost that even further, even in the face of new rivals like Tower of Fantasy that has just arrived this month. Genshin is the gold standard at the moment and it’s going to be hard to compete with it as it expands to seven massive regions over the next few years.

In fact, Samsung says the new Galaxy Watch 5 Pro is ideal for anyone with a love for the outdoors, thanks to its tough titanium chassis and Sapphire Crystal display.
