人工智能有用吗？
Can Artificial Intelligence Help?
Computer algorithms(算法) today are performing incredible tasks...
...with high accuracies, at a massive scale, using human-like intelligence.
And this intelligence of computers is often referred to as AI or artificial intelligence.
AI is poised(准备) to make an incredible impact on our lives in the future.
Today, however, we still face massive challenges...
...in detecting and diagnosing several life-threatening illnesses,such as infectious diseases and cancer.
Thousands of patients every year lose their lives due to liver and oral cancer.
Our best way to help these patients is to perform early detection and diagnoses of these diseases.
So how do we detect these diseases today, and can artificial intelligence help?
In patients who, unfortunately, are suspected of these diseases,...
...an expert physician first orders very expensive medical imaging technologies
...such as fluorescent(荧光) imaging, CTs, MRIs, to be performed.
Once those images are collected,...
...another expert physician then diagnoses those images and talks to the patient.
As you can see, this is a very resource-intensive process,...
...requiring both expert physicians, expensive medical imaging technologies,...
...and is not considered practical for the developing world.
And in fact, in many industrialized nations, as well.
So, can we solve this problem using artificial intelligence?
Today, if I were to use traditional artificial intelligence architectures to solve this problem,...
...I would require 10,000 —
I repeat, on an order of 10,000 of these very expensive medical images first to be generated.
After that, I would then go to an expert physician,who would then analyze those images for me.
And using those two pieces of information,...
I can train a standard deep neural(神经的) network or a deep learning network to provide patient's diagnosis.
Similar to the first approach,...
...traditional artificial intelligence approaches suffer from the same problem.
Large amounts of data, expert physicians and expert medical imaging technologies.
