You don't understand anything until you learn it more than one way.

This is a tricky domain because, unlike simple arithmetic, to solve a calculus problem - and in particular to perform integration - you have to be smart about which integration technique should be used: integration by partial fractions, integration by parts, and so on.

If you just have a single problem to solve, then fine, go ahead and use a neural network. But if you want to do science and understand how to choose architectures, or how to go to a new problem, you have to understand what different architectures can and cannot do.

There was a failure to recognize the deep problems in AI; for instance, those captured in Blocks World. The people building physical robots learned nothing.

There are three basic approaches to AI: Case-based, rule-based, and connectionist reasoning.

We wanted to solve robot problems and needed some vision, action, reasoning, planning, and so forth. We even used some structural learning, such as was being explored by Patrick Winston.

Once when I was standing at the base, they started rotating the set and a big, heavy wrench fell down from the 12 o'clock position of the set, and got buried in the ground a few feet from me. I could have been killed!

In general we are least aware of what our minds do best.

I heard that the same thing occurred in a scene in Alien, where the creature pops out of the chest of a crewman. The other actors didn't know what was to happen; the director wanted to get true surprise.

By the way, it was his simulations that helped out in Jurassic Park - without them, there would have been only a few dinosaurs. Based on his techniques, Industrial Light and Magic could make whole herds of dinosaurs race across the screen.

The basic idea in case-based, or CBR, is that the program has stored problems and solutions. Then, when a new problem comes up, the program tries to find a similar problem in its database by finding analogous aspects between the problems.

No computer has ever been designed that is ever aware of what it's doing; but most of the time, we aren't either.

When David Marr at MIT moved into computer vision, he generated a lot of excitement, but he hit up against the problem of knowledge representation; he had no good representations for knowledge in his vision systems.

You don't understand anything until you learn it more than one way.

I think Lenat is headed in the right direction, but someone needs to include a knowledge base about learning.

Around 1967 Dan Bobrow wrote a program to do algebra problems based on symbols rather than numbers.

Societies need rules that make no sense for individuals. For example, it makes no difference whether a single car drives on the left or on the right. But it makes all the difference when there are many cars!

Kubrick's vision seemed to be that humans are doomed, whereas Clarke's is that humans are moving on to a better stage of evolution.

Stanley Kubrick knew we had good graphics around MIT and came to my lab to find out how to do it. We had some really good stuff. I was very impressed with Kubrick; he knew all the graphics work I had ever heard of, and probably more.

I believed in realism, as summarized by John McCarthy's comment to the effect that if we worked really hard, we'd have an intelligent system in from four to four hundred years.

Artificial intelligence is the science of making machines do things that would require intelligence if done by men.

I travel all over the world, usually 10 months out of the year. I stay at a lot of hotels, and the ones I like best are clean and not complicated. You go to bed and say, 'Wow, I feel comfortable.'

Inaction breeds doubt and fear. Action breeds confidence and courage.

My dad was an FBI agent. My mom and dad were straight arrow types, and I had a conservative, suburban Orange County upbringing.

Pete Davidson - he's in the movie 'Trainwreck.' He has a small part in it. I told Lorne Michaels about him, said he was really funny.

The human imagination can connect to practically anything.

The certainty that our football, the football of Spain, is recognised, that's very important to us - perhaps more important than the successes and the joy that you can create. Football hasn't always been appreciated, and luckily our football is appreciated now, at all levels of society.

I am very conscious that you can't condemn people of an earlier era by the standards of ours.

There is nothing wrong with eating sweets, fried foods, pastries, even drinking soda every now and then, but food manufacturers have made eating these formerly expensive and hard-to-make treats so cheap and easy that we're eating them every day.

Whatever age you think I am, you're probably right.

Although his crusade in 1957 occurred at a time in our nation's history when race divided all, Reverend Graham refused to preach in segregated audiences.

Before 9/11 there were weak procedures, willingness, and mechanisms for communicating among agencies for foreign intelligence and the FBI with its focus on law enforcement. The domestic-vs.-foreign barrier has been solved by the reforms after 9/11 that established the DNI.

Humans are so much like bubbles. Vivid and pretty to look at, But prick them once and they burst.

Contrary to the myth that Mr. Bush cut taxes only for the wealthy, the 2001 tax cut reduced taxes for every income-tax payer in the country.

He that conceals his grief finds no remedy for it.

The billionaire who sits on his money and doesnt do anything for the common good Im not interested in that person.

Be curious enough to keep an open mind to what's happening around you in society. You can look at yourself and the world at the same time.

Africa has no future.

I really wanted to work with Kate Mulgurew and Natasha Lyonne.

In France, if you have any sort of talent, you'd better keep it here. And if you're going to go abroad, it had better not be America. The old battle - American versus Frog cinema. It's ridiculous.

You try to hide your emotions, so as not to show weaknesses to others. I believe it's the same for every sportsman.

I'm very blessed and fortunate that people want to go see my movies.

Between 1995 and 2009, Western Europe's entrepreneurs created jobs faster than the U.S. did, and European economies exported more than the BRIC countries of Brazil, Russia, India and China. Eastern Europe's productivity increased more rapidly than East Asia's.

When I was a kid, I thought I was Wonder Woman.

Dont call the alligator big mouth until you have crossed the river.
