Twitter offers cash 'bounty' to hackers who can find biases in image algorithm

  • Arabic

Twitter Inc said on Friday it will launch a competition for computer researchers and hackers to identify biases in its image-cropping algorithm, after a group of researchers previously found the algorithm tended to exclude black people and men.

The competition is part of a wider effort across the tech industry to ensure artificial intelligence technologies act ethically.

The social networking company said in a blog post that the bounty competition was aimed at identifying "potential harms of this algorithm beyond what we identified ourselves."

Following criticism in 2020 about image previews in posts excluding black people's faces, the company said in May a study by three of its machine learning researchers found the algorithm did in fact display “unequal treatment based on demographic differences."

It favoured women more highly than men by 8 per cent, and it favoured photos of white people over black individuals by 4 per cent, Twitter said. Within those demographics, white women were more highly favoured by 7 per cent compared with black women; and white men were favoured 2 per cent more than black men.

The analysis also delved into objectification biases – or the “male gaze” – after people on Twitter identified instances where cropping chose a woman’s chest or legs as a salient feature. However, they “did not find any evidence that the algorithm cropped images of men or women in areas other than their face at a significant rate".

To determine this, they gave the algorithm 100 randomly chosen images and found that only three centred on bodies over faces. It stated that "when images weren't cropped at the head, they were cropped to non-physical aspects of the image, such as a number on a sports jersey".

"We considered the trade-offs between the speed and consistency of automated cropping with the potential risks we saw in this research. One of our conclusions is that not everything on Twitter is a good candidate for an algorithm, and in this case, how to crop an image is a decision best made by people," Rumman Chowdhury, Twitter's director of software engineering, wrote in a blog post in May.

On Friday, Twitter released publicly the computer code that decides how images are cropped in the Twitter feed, and said participants are asked to find how the algorithm could cause harm, such as stereotyping or denigrating any group of people.

The winners will receive cash prizes ranging from $500 to $3,500 and will be invited to present their work at a workshop hosted by Twitter at Def Con in August, one of the largest hacker conferences held annually in Las Vegas.

Terror attacks in Paris, November 13, 2015

- At 9.16pm, three suicide attackers killed one person outside the Atade de France during a foootball match between France and Germany- At 9.25pm, three attackers opened fire on restaurants and cafes over 20 minutes, killing 39 people- Shortly after 9.40pm, three other attackers launched a three-hour raid on the Bataclan, in which 1,500 people had gathered to watch a rock concert. In total, 90 people were killed- Salah Abdeslam, the only survivor of the terrorists, did not directly participate in the attacks, thought to be due to a technical glitch in his suicide vest- He fled to Belgium and was involved in attacks on Brussels in March 2016. He is serving a life sentence in France

Navdeep Suri, India's Ambassador to the UAE

There has been a longstanding need from the Indian community to have a religious premises where they can practise their beliefs. Currently there is a very, very small temple in Bur Dubai and the community has outgrown this. So this will be a major temple and open to all denominations and a place should reflect India’s diversity.

It fits so well into the UAE’s own commitment to tolerance and pluralism and coming in the year of tolerance gives it that extra dimension.

What we will see on April 20 is the foundation ceremony and we expect a pretty broad cross section of the Indian community to be present, both from the UAE and abroad. The Hindu group that is building the temple will have their holiest leader attending – and we expect very senior representation from the leadership of the UAE.

When the designs were taken to the leadership, there were two clear options. There was a New Jersey model with a rectangular structure with the temple recessed inside so it was not too visible from the outside and another was the Neasden temple in London with the spires in its classical shape. And they said: look we said we wanted a temple so it should look like a temple. So this should be a classical style temple in all its glory.

It is beautifully located - 30 minutes outside of Abu Dhabi and barely 45 minutes to Dubai so it serves the needs of both communities.

This is going to be the big temple where I expect people to come from across the country at major festivals and occasions.

It is hugely important – it will take a couple of years to complete given the scale. It is going to be remarkable and will contribute something not just to the landscape in terms of visual architecture but also to the ethos. Here will be a real representation of UAE’s pluralism.
