AI Outwits Doctors at Detecting Skin Cancer

It can be cured if detected early, but many cases are only diagnosed when the cancer is more advanced and harder to treat

An Artificial Intelligence (AI) system has been found to detect skin cancer more accurately than a group of experienced dermatologists from 17 countries around the world, a study said on Tuesday.

In the experiment, the team of researchers from Germany, France and the US trained a form of AI or Machine Learning known as a deep learning convolutional neural network (CNN) to identify skin cancer by showing it more than 100,000 images of malignant melanomas — the most lethal form of skin cancer — as well as harmless moles.

When its performance was compared with that of 58 international dermatologists, the CNN missed fewer melanomas and misdiagnosed benign moles less often as malignant than the group of dermatologists, showed the findings published in the journal Annals of Oncology.

“The CNN works like the brain of a child. To train it, we showed the CNN more than 100,000 images of malignant and benign skin cancers and moles and indicated the diagnosis for each image,” said first author of the study Professor Holger Haenssle from the University of Heidelberg in Germany.

“Only dermoscopic images were used, that is lesions that were imaged at a 10-fold magnification. With each training image, the CNN improved its ability to differentiate between benign and malignant lesions,” Haenssle added.

A CNN is an artificial neural network inspired by the biological processes at work when nerve cells (neurons) in the brain are connected to each other and respond to what the eye sees.

The CNN is capable of learning fast from images that it “sees” and teaching itself from what it has learned to improve its performance — a process known as Machine Learning.

“These findings show that deep learning convolutional neural networks are capable of out-performing dermatologists, including extensively trained experts, in the task of detecting melanomas,” Haenssle said.

The incidence of malignant melanoma is increasing, with an estimated 232,000 new cases worldwide and around 55,500 deaths from the disease each year.

It can be cured if detected early, but many cases are only diagnosed when the cancer is more advanced and harder to treat.

But despite the promising results from the experiment, the researchers do not envisage that the CNN would take over from dermatologists in diagnosing skin cancers, but that it could be used as an additional aid.

“This CNN may serve physicians involved in skin cancer screening as an aid in their decision whether to biopsy a lesion or not,” Haenssle said. (IANS)

India can Lead in Setting Standards for Ethical use of AI: Microsoft Executive

With the government focusing on the use of Artificial Intelligence (AI) and Machine Learning (ML) as people are increasingly adopting digital technologies, India can lead in setting standards for ethical use of AI, a top Microsoft executive said on Friday.

“The real application of AI needs to be to empower human ingenuity and to accelerate innovation for all kinds of work and thinking,” Anant Maheshwari, President, Microsoft India, told IANS.

In an earlier interview with IANS on the eve of 73rd Independence Day, Prime Minister Narendra Modi said that the government is trying to leverage technology like AI and ML to improve school education.

Finance Minister Nirmala Sitharaman in her maiden Budget speech in July announced that the government will lay focus on new-age skills like AI, Internet of Things, Big Data, 3D Printing, Virtual Reality and Robotics.

“About 91 per cent of organisations today plan to leverage AI within the next three years to drive their businesses and the biggest issue they point out for not using it right now is lack of skills,” Maheshwari said.

“India is among the top three geographies globally in terms of the supply of skills for AI and that bodes very well for India to lead and contribute significantly in the world of AI,” Maheshwari added.

“We can very much create use cases and the standards for ethical use of AI. I am quite optimistic on the role India will play in the emergence of AI and the principles of AI,” he noted.

Microsoft on Friday announced a partnership with the Indian School of Business (ISB) to equip business leaders with tools and strategies to make their organisations AI-driven.

“The initiative we are launching today between ISB and Microsoft really addresses not only the issue of creating right awareness around the skill set needed to drive the AI strategies, but also provide the tool sets to create the AI strategies, to create the discussion around what culture is needed inside an organisation to drive AI and also have the awareness of the ethics and principles around it,” Maheshwari emphasised.
