Summary
Today's AI algorithms require tens of thousands of expensive medical images to detect a patient's disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm -- and can even use photos taken on doctors' cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.

| 0:00.0 | This TED Talk features medical technology scientist Prateek Shah recorded live at TED Global 2017. |
| 0:09.1 | Computer algorithms today are performing incredible tasks with high accuracy at a massive scale using human-like intelligence. |
| 0:18.3 | And this intelligence of computers is often referred to as AI or artificial intelligence. |
| 0:24.2 | AI is poised to make an incredible impact |
| 0:27.1 | on our lives in the future. |
| 0:29.3 | Today, however, we still face massive challenges |
| 0:33.2 | in detecting and diagnosing several life-threatening illnesses |
| 0:36.7 | such as infectious diseases and cancer. |
| 0:40.1 | Thousands of patients every year lose their lives to deliver an oral cancer. |
| 0:46.2 | Our best way to help these patients is to perform early detection and diagnoses of these diseases. |
| 0:53.8 | So how do we detect these diseases today, |
| 0:56.0 | and can artificial intelligence help? |
| 1:00.0 | In patients who unfortunately are suspected of these diseases, |
| 1:03.0 | an expert physician first orders very expensive medical imaging technologies |
| 1:09.0 | such as fluorescent imaging, CTs, MRIs to be performed. |
| 1:13.4 | Once those images are collected, another expert physician then diagnoses those images and talks to the patient. |
| 1:20.8 | As you can see, this is a very resource-intensive process requiring both expert physicians' expensive |
| 1:27.2 | medical imaging technologies, and is not |
| 1:29.3 | considered practical for the developing world, and in fact, in many industrialized nations as well. |
| 1:35.3 | So can we solve this problem using artificial intelligence? |
| 1:39.3 | Today, if I were to use traditional artificial intelligence architectures to solve this problem, |
| 1:45.5 | I would require 10,000. |
