Microsoft’s Improved Face API More Accurately Recognizes a Range of Skin Tones

Currently, facial recognition tools tend to perform best on men with lighter skin and worst on women with darker skin

Addressing two weak points in the currently available face recognition technologies, Microsoft has updated its facial recognition tools that can better identify people with darker skin tones than before.

With the new improvements, the tools were able to reduce the error rates for men and women with darker skin by up to 20 times.

“For all women, the error rates were reduced by nine times. Overall, with these improvements, they were able to significantly reduce accuracy differences across the demographics,” Microsoft said in a blog post written by John Roach late on Tuesday.

Currently, facial recognition tools tend to perform best on men with lighter skin and worst on women with darker skin.

“That improvement addresses recent concerns that commercially available facial recognition technologies more accurately recognised gender of people with lighter skin tones than darker skin tones, and that they performed best on males with lighter skin and worst on females with darker skin,” Roach wrote.

The higher error rates on females with darker skin highlights an industrywide challenge — Artificial Intelligence (AI) technologies are only as good as the data used to train them.

If a facial recognition system is to perform well across all people, the training dataset needs to represent a diversity of skin tones as well as factors such as hairstyle, jewellery and eyewear.

The team responsible for the development of facial recognition technology at Microsoft, which is available to customers as the Face API via Azure Cognitive Services, worked with experts on bias and fairness across Microsoft to improve a system called the gender classifier, focusing specifically on getting better results for all skin tones.

“We had conversations about different ways to detect bias and operationalise fairness. We talked about data collection efforts to diversify the training data. We talked about different strategies to internally test our systems before we deploy them,” said Hanna Wallach, Senior Researcher in Microsoft’s New York research lab.

Wallach and her colleagues provided “a more nuanced understanding of bias,” said Cornelia Carapcea, a Principal Programme Manager on the Cognitive Services team, and helped her team create a more robust dataset “that held us accountable across skin tones.” (IANS)

Microsoft Wants Regulation For Facial Recognition Technology To Start in 2019

Given the potential for abuse of the fast advancing facial recognition technology, governments across the world need to start adopting laws to regulate this technology in 2019, Microsoft President Brad Smith has said.

“Unless we act, we risk waking up five years from now to find that facial recognition services have spread in ways that exacerbate societal issues,” warned Smith in a blog post on Thursday.

“The time for action has arrived,” he said, adding that the industry must also exercise restraint while using this technology.

Speaking of the benefits of the technology, the Microsoft President mentioned that police in New Delhi recently trialled facial recognition technology and identified almost 3,000 missing children in four days.

Similarly, historians in the US have used the technology to identify the portraits of unknown soldiers in Civil War photographs taken in the 1860s.

Researchers successfully used facial recognition software to diagnose a rare, genetic disease in Africans, Asians and Latin Americans.

And in October, the National Australia Bank designed a proof of concept to enable customers to withdraw money from an Automatic Teller Machine using facial recognition and a PIN.

But at the same time, the potential for abuse of this technology is huge, Smith said, adding that certain uses of this technology could lead to biased decisions and discrimination.

Moreover, the widespread use of this technology can lead to new intrusions into people’s privacy, he said.

“The use of facial recognition technology by a government for mass surveillance can encroach on democratic freedoms,” Smith added.

“While we believe that new laws and regulations are indispensable, we also recognise that they are not a substitute for the responsibility that needs to be exercised by tech companies,” he said.

Microsoft is one of several companies playing a leading role in developing facial recognition technology.

The company, Smith said, would start adopting new principles to manage the issues surrounding facial recognition technology in the first quarter of 2019. (IANS)
