This is a classroom for artificial intelligence or AI.
这是人工智能或者AI的教室。
Its teacher Rishi Rawat is feeding the computer more samples of cancer cells.
他的老师伊西·路瓦特正在给计算机提供更多的癌细胞样本。
They're like a computer brain, and you can put the data into them
它就像一个计算机大脑，你可以将数据录入，
and they will learn the patterns and the pattern recognition that's important for making decisions.
计算机可以学习这些模式、模式识别，这对做决策非常重要。
Decisions by doctors to determine the best treatment for their patients.
医生帮助患者确定最佳治疗方案。
Machines are not gonna take the place of doctors.
机器不会取代医生。
Computers will not treat patients, but they will help make certain decisions
计算机不能治疗患者，但是可以帮助作出某些决策，
and look for things that the human brain can't recognize these patterns by itself.
并且寻找某些人类大脑无法识别的东西。
For example, once a cancerous tumor is removed from a patient with breast cancer，
举个例子，即使患有乳腺癌的患者体内的癌性肿瘤已经移除了，
the doctors still have to treat the patient to reduce the risk of recurrence.
医生仍然需要给患者提供治疗，以降低复发风险。
The type of treatment depends on the type of cancer and whether the tumors driven by estrogen.
治疗的类型取决于癌症类型，以及肿瘤是否受雌激素驱动。
So what the pathologist has to do is to count what percentage of the cells here are brown versus what percentage are not.
因此，病理学家需要做的是计算这里的棕色和非棕色细胞的百分比分别是多少。
This process could take days or even longer.
这个过程可能需要数天甚至更长时间。
In developing nations, they don't necessarily have access to do this at all,
在发展中国家，他们不一定能够完全做到这一点，
and so there's a great need there to be able to diagnose these cancers correctly.
因此他们非常需要正确诊断这些癌症。
The computer can do something better than just count cells.
计算机可以做的不仅仅是计算细胞。
AI can recognize complicated patterns on how the cells are arranged,
人工智能可以识别细胞排列的复杂模式，
with the hope in the near future of making a quick and more reliable diagnosis that is free of human error.
在不久的将来希望可以做出更加快速，可靠的诊断，避免人为错误。
Are they disordered? Are they in a regular spacing?
它们排列混乱了吗？它们的间隔是否均匀？
What's going on exactly with the arrangement of cells in the tissue?
组织中的细胞排列到底出了什么问题？
We can do this instantaneously for almost no cost in the developing world.
在发展中国家，我们可以几乎不花任何费用做这件事。
Scientists say the time is ripe for the marriage between computer science and cancer research.
科学家们表示是时候将计算机科学与癌症研究结合了。
All of a sudden, we have the computing power to really do it in real time.
突然之间，我们可以通过计算能力实时完成这些。
We have the ability of scanning a slide to high enough resolution
我们能够将幻灯片扫描到足够高的分辨率，
so that the computer can see every little feature of the cancer.
以便计算机可以看到癌症的每个细微的特征。
So it's a convergence of technology. We couldn't have done this.
所以这是技术的融合。我们不可能做到这一点。
We didn't have the computing power to do this several years ago, but now it's all changed.
几年前我们没有计算能力，但现在情况已经完全改变了。
The research now was on breast cancer,
现在的研究是关于乳腺癌，
but doctors predict artificial intelligence will eventually be used to help treat patients with all forms of cancer.
但医生预测人工智能最终将用于帮助治疗各类癌症患者。
