Recycling has become commonplace, as people recognize the need to care for the environment. Yet most peoples recycling consciousness extends only as far as paper

2、, bottles, and cans. People seldom find themselves facing the growing problem of e-waste.E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced device and the majority of them end up in landfills(垃圾填埋地). Some people who track such waste say that users throw away

3、nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every day. Unless we can find a safe replacement, this e-waste may get into the ground and poison the water with dangerous toxins(毒素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates

4、 the air.However, e-waste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.A growing number of states have adopted laws to

5、ban dumping(倾倒)e-waste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal(处置)in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposi

10、 in 2012 in Forbes magazine. By 2016, with the rise of big datas fast-growing cousin deep learning, we had become more certain: “Data is the new oil,” stated Fortune magazine.Amazons Neil Lawrence has a slightly different comparison: Data is coal. Not coal today, though, but coal in the early days o

11、f the 18th century, when Thomas Newcomen invented the steam engine. Newcomen built his device to pump water out of the southwests rich tin (锡) mines.The problem, as Lawrence said, was that the pump was rather more useful to those who had a lot of coal than those who didnt: it was good, but not good

12、enough to be able to buy enough coal in to run it. That was so true that the first of Newcomens steam engines wasnt built in a tin mine, but in coal works near Dudley.So why is data coal? The problem is similar: there are a lot of Newcomen in the world of deep learning. New companies are coming up w

That change, Lawrence said, “made the steam engine much more efficient, an

15、d thats what triggered the industrial revolution.”Whether data is oil or coal, then, theres another way the comparison holds up: a lot of work is going into trying to make sure we can do more, with less.“If you look at all the areas where deep learning is successful, theyre all areas where theres lo

16、ts of data,” points out Lawrence. Thats great if you want to classify images of cats, but less helpful if you want to use deep learning to diagnose rare illnesses. “Its generally considered unacceptable to force people to become sick in order to acquire data.”Its not as impressive as teaching a comp

17、uter to play a game better than any human alive, but “data efficiency” is a vital step if deep learning is to move away from simply taking in large amounts of data and giving out the best correlations (关联) possible.12The first of Newcomens steam engines wasnt built in a tin mine because_.Aits operat
