Twitter is removing its image-cropping algorithm after a review found bias in the automated system.
On Wednesday, the social media platform announced that it had analysed the algorithm after getting feedback that it "didn't serve all people equitably".
After reviewing the model over several months, it discovered that the image-cropping algorithm chose points of focus on pictures, which Twitter calls the saliency, and found occasional instances of bias in cropped pictures in favour of women and lighter skin tones.
According to findings, there was an 8 per cent difference from demographic parity in favour of women, 4 per cent difference in favour of white individuals overall, while comparisons of white and black women showed a difference of 7 per cent in favour of white women. In comparisons of black and white men, there was a 2 per cent difference in favour of white 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".
Twitter launched the saliency algorithm in 2018 to crop images to improve consistency in the size of photos and allow viewers to see more tweets in one glance.
However, considering the controversial findings, they are dropping the feature to “give people more control over how their images appear while also improving the experience of people seeing the images in their timeline".
In a blog post, Rumman Chowdhury, Twitter's director of software engineering, said that "even if the saliency algorithm was adjusted to reflect perfect equality across race and gender subgroups, they were concerned by representation harm of the automated algorithm when people weren't allowed to represent themselves as they wish".
"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."
The news comes a month after Twitter announced it was launching an initiative to analyse its algorithm fairness on social media.

When Umm Kulthum performed in Abu Dhabi
Known as The Lady of Arabic Song, Umm Kulthum performed in Abu Dhabi on November 28, 1971, as part of celebrations for the fifth anniversary of the accession of Sheikh Zayed bin Sultan Al Nahyan as Ruler of Abu Dhabi. A concert hall was constructed for the event on land that is now Al Nahyan Stadium, behind Al Wahda Mall. The audience were treated to many of Kulthum's most well-known songs as part of the sold-out show, including Aghadan Alqak and Enta Omri.
Game Of Thrones Season Seven: A Bluffers Guide
Want to sound on message about the biggest show on television without actually watching it? Best not to get locked into the labyrinthine tales of revenge and royalty: as Isaac Hempstead Wright put it, all you really need to know from now on is that there’s going to be a huge fight between humans and the armies of undead White Walkers.
The season ended with a dragon captured by the Night King blowing apart the huge wall of ice that separates the human world from its less appealing counterpart. Not that some of the humans in Westeros have been particularly appealing, either.
Anyway, the White Walkers are now free to cause any kind of havoc they wish, and as Liam Cunningham told us: “Westeros may be zombie land after the Night King has finished.” If the various human factions don’t put aside their differences in season 8, we could be looking at The Walking Dead: The Medieval Years.

What is blockchain?
Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.
The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.
Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.
However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.
Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.
