A team of Google researchers has used a deep-learning algorithm to detect lung cancer accurately from computed scans.

The work demonstrates the potential for Artificial Intelligence (AI) to increase both accuracy and consistency, which could help accelerate adoption of lung cancer screening worldwide.

Lung cancer is the deadliest of all cancers worldwide — more than breast, prostate, and colorectal cancers combined — and it’s the sixth most common cause of death globally, according to the World Health Organization.

“Using advances in 3D volumetric modeling alongside datasets from our partners (including Northwestern University), we’ve made progress in modeling lung cancer prediction as well as laying the groundwork for future clinical testing,” Shravya Shetty, M.S. Technical Lead at Google explained in a blog post late Monday.

Google researchers created a model that can not only generate the overall lung cancer malignancy prediction (viewed in 3D volume) but also identify subtle malignant tissue in the lungs (lung nodules).

In the research, Google AI leveraged 45,856 de-identified chest CT screening cases (some in which cancer was found).

“When using a single CT scan for diagnosis, our model performed on par or better than the six radiologists. We detected five per cent more cancer cases while reducing false-positive exams by more than 11 per cent compared to unassisted radiologists in our study,” said Google.

For an asymptomatic patient with no history of cancer, the AI system reviewed and detected potential lung cancer that had been previously called normal.

These initial results are encouraging, but further studies will assess the impact and utility in clinical practice, said Google.

Here’s Why Alphabet CEO Sundar Pichai Believes That Artificial Intelligence Needs To Be Regulated

Joining Microsoft President Brad Smith and Tesla CEO Elon Musk, Alphabet and Google CEO Sundar Pichai on Monday called for new regulations for Artificial Intelligence (AI), saying the only question now is how to approach it.

Although new regulation is needed, “a cautious approach is required that might not see significant controls placed on AI,” Pichai who was last month took over as the CEO of Alphabet, Google’s parent company, in an editorial piece in The Financial Times.

“There is no question in my mind that artificial intelligence needs to be regulated. It is too important not to. The only question is how to approach it”.

“Companies such as ours cannot just build promising new technology and let market forces decide how it will be used. It is equally incumbent on us to make sure that technology is harnessed for good and available to everyone,” Pichai wrote.

According to CNET, the timing of the editorial coincides with a big push from Google to reveal some of the results of its own work in AI and bring tools it has developed out into the world.

The Alphabet CEO stressed that “international alignment will be critical to making global standards work” on AI.

We need to take a “principled approach to applying AI, said the company, while offering Google’s “expertise, experience and tools.”

“We need to be clear-eyed about what could go wrong,” he said.

His comments come as lawmakers and governments globally are considering to limit the use of AI in fields such as face recognition system – an issue close to Microsoft President Brad Smith’s heart who has often criticized the technology, urging governments to enact legislation regarding the technology.

“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,” said Smith.

Advanced AI which is beyond chat bots will soon be used to manipulate social media platforms like Facebook, Twitter or Instagram, Tesla CEO Elon Musk warned recently.

In his famous debate with former Alibaba Chairman Jack Ma, Musk entered into a lassic argument over the capabilities of emerging technologies like AI.

Musk said that computers will one day surpass humans in “every single way”. He has predicted that a single company that develops “God-like super intelligence” might achieve world domination.
