Can the Computer Learn from Experience

计算机会总结经验吗

Computers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computer’s progress in the ability to learn from experience.

Because the game requires logical reasoning, chess would seem to be perfectly suited to the computer .all a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in practice it is impossible. Today, a powerful computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chess—literally trillions. Even if such a program were written (and in theory it could be ,given enough people and enough time), there is no computer capable of holding that much data.

Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own programm, to deal with a relatively unstructured situation—in a word, to “think” for itself . In fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their chess games. But they have gone on from there to reason and learn, and sometimes to win the game.

There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted , winning a game of chess is not an earthshaking event even when a computer does it . But there are many serious human problems which ban be fruitfully approached as games. The Defense Department uses computers to play war games and work out strategies for dealing with international tensions. Other problems—international and interpersonal relations , ecology and economics , and the ever-increasing threat of world famine—can perhaps be solved by the joint efforts of human beings and truly intelligent computers .

　　　　　　　　　　　　　You Call This a Good Economy

　　　　　　　　　　　　　　这能称之为上佳经验

You have to have lived in the 1950s and 1960s to have experienced a good economy. In the period between 1950 and 1970 it was the rule—rather than the exception—that an ordinary family, without higher education, could sustain itself decently on the income of a single breadwinner（养家糊口旳人）. In 1955, when I was 19 and living in Brooklyn, N. Y., my father, who had a sixth-grade education, maintained our family of five on a wage of $82 a week as a bookbinder. My mother taught us fairness and compassion; my father, discipline and enterprise.

The U. S. economy in those years was good. Then where did this good economy go? It was inflated away. The price of gold, which I take as proxy for the prices of all goods, was $35 an ounce in those years. It is at roughly ten times that price today.

There is another answer, though: inflation caused the entire work force to be moved into higher tax groups, thus reducing after-tax purchasing power. That is, my father’s bindery job in1954 paid $82 a week, with $80 after deductions; today, at $ 820 per week the net would be $662.

To ordinary people, the economy doesn’t look very good at all. After-tax incomes continue to decrease in purchasing power. The jobs offered in the employment ads pay only a little more than the minimum wage, maybe $5 an hour, which, after payroll deductions, yields $4 an hour. Compare that with minimum-wage jobs of the early 1950s, when 75 cents was worth today’s $7.50 before and after taxes.

2 inflate:通货膨胀

3 proxy: the authority to act for another

4 payroll: a list of employees and the wages due to each

Are Experts Always Right

专家总是对旳吗

The world has become so complicated that we’ve lost confidence in our ability to understand and deal with it. But common sense is useful now as it ever was. No amount of expertise substitutes for an intimate knowledge of a person or a situation. At times you just have to trust your own judgement.

It almost cost me my life to learn that. I was reading a book one day, idly scratching the back of my head, when I noticed that, in one particular spot, the scratching echoed inside my head like fingernails on an empty cardboard carton, I rushed off to my doctor.

“Got a hole in your head, have you?” he teased. “It’s nothing—just one of those little scalp nerves sounding off.”

Two years and four doctors later, I was still being told it was nothing. To the fifth doctor. I said, almost in desperation,”But I live in tis body. I know something’s different.”

“If you won’t take my word for it,I’ll take an X-ray and prove it to you,” he said.

Well, there it was, of course, the tumor that had made a hole as big as an eye socket in the back of my skull. After the operation, a young resident paused by my bed. ”It’s a good thing you’re so smart,” he said.” Most patient die of these tumors because we don’t know they’re there until it is too late.”

I’m really not so smart. And I’m too docile in the face of authority. I should have been more aggressive with those first four doctors. It’s hard to question opinions delivered with absolute certainty.

Experts always sound so sure. Nevile Chamberlain, the British prime minister, was positive, just before the start of World War II, that there would be “peace for our time.” Producer Irving Thalberg did not hesitate to advise Louis B. Mayer against buying the rights to Gone With the Wind because “no Civil War picture ever made a nickel.” Even Abraham Lincoln surely believed it when he said in his Gettysburg Address:” The world will little note, nor long remember, what we say here…”

We should not, therefore, be intimidated by experts. When it’s an area we really know about—our bodies, our families, our houses—let’s listen to what the experts say, then make up our own minds.

Just Call Me Mister

1 On cold days people in Manhattan like to take their children to PlaySpace, an indoor playground full of wonderful climbing and sliding contraptions. There’s just one irritating detail: when you pay your money, the cashier pulls out a felt-trip marker and an adhesive lapel tag and asks you your name.

“Frum,” I say.

“No, your first name.”

“What do you need my first name for?”

“To write on the tag, so all the children and the staff will know what to call you.”

“In that case, write ‘Mr. Frum.’”

2 At which I am shot a look as if I had asked to be called to Duke of Plaza Toro.

3 In encouraging five-year-olds to address grownups by their first names, PlaySpace is only slightly ahead of the times. As a journalist, I faithfully report that the custom of addressing strangers formally is as dead as the practice of leaving a visiting card.

4 There’s hardly a secretary left who does not reply, when I give a message fro her boss, “I’ll tell him you called, David.” Or a public relations agent, whether in Bangor or Bangkok, who does not begin his telephonic spiel with a cheerful “Hello, David!”

5 You don’t have to be a journalist to collect amazing first-name stories. Place a collect call, and the operator first-names you. The teenager behind the counter at a fast-food restaurant asks a 70-year-old customer for his first name before taking his order.

6 Habitual first-names claim they are motivated by nothing worse than uncontrollably high-spirited friendliness. I don’t believe it. I f I asked the fast-food order-takers to lend me $50, their friendliness would vanish in a whoosh. The PR man drops all his cheerfulness the moment he hears I won’t go along with his story idea. No, it’s not friendliness that drives first-namers; it’s aggression. The PR agents who call me David uninvited would never, if they could somehow get him on the phone, address press baron Rupert Murdoch that way. The woman at the bank who called me David would never first-name the bank’s chairman. Like the mock-cheery staff at PlaySpace, they are engaged in a smiley-faced act of belittlement, an assertion of power disguised as good cheer.

Notes

1 contraptions:(informal)mechanical devices;gadgets

2 felt-tip marker:软笔尖旳颜色笔

3 adhesive lapel tag:不干胶标牌

4 Duke of Plaza Toro: Duke is a nobleman with the highest hereditary rank, especially in Britain. Plaza Tora is Spanish, something like “Bull Fighting Ring” in English

5 Bangor:City of South central Maine

6 Bangkok:Captical of Thailand,曼谷

7 spiel(slang) a lengthy, usually extravagant, speech or argument intended to be persuasive

8 collect call:a telephone call with payment to be made by the receiver

9 press baron:Baron is the lowest male rank of nobility, but here it stands for a man with great power in press

10 mock: simulated

11 cheery:cheerful
