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

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 am a big believer in the fact that all authors really write only one book.

At its very core, virtual reality is about being freed from the limitations of actual reality. Carrying your virtual reality with you, and being able to jump into it whenever and wherever you want, qualitatively changes the experience for the better. Experiencing mobile VR is like when you first tried a decent desktop VR experience.

The vast majority of politicians think they are functioning on high principle.

You know, something happened to me when I became 70. I started to feel a tremendous love for the human race, and life and this planet, the universe, the whole shebang.

Iggy Pop, or should I say Iggy's people, had reached out to me saying he was a True Blood fan, and if any opportunities come up, to please keep Iggy in mind. We sent Iggy the demo of 'LB&R'. He loved it and said, 'Sign me up.'

Imagine how different those classrooms could be if hundreds of Nigeria's most talented recent graduates and professionals channeled their energy not only into the country's banks, but into making education in the country a force for transformation.

Climate change is obviously happening and there is obviously a man made contribution.

I wouldn't wear really short dresses anymore - just don't feel comfortable in them.

I love hanging out at home with my kid. It's hard to get me to leave the house.

The Bristol Channel was always my guide, and I was always able to draw an imaginary line from my bed to our house over in Wales. It was a great comfort.

Love is always being given where it is not required.

I don't have a Twitter account. I don't go to fan club gatherings. I'm not one of those actors who spends a lot of time engaging with the audience.

I don't care how fancy you wrap trash, it's still trash.

In the case of climate change, the threat is long-term and diffuse and requires broad international action for the benefit of people decades in the future. And in politics, the urgent always trumps the important, and that is what makes it a very difficult and challenging issue.

To say that I'm enjoying a millionaire's lifestyle-well, I can tell you, I guess a millionaire's income doesn't go very far these days.

Whenever I can afford to do something, I do it.

Act with purpose, courage, confidence, competence and intelligence until these qualities 'lock in' to your subconscious mind.

Once a person has sinned and repeated the sin, [he treats it] as if it has become permitted.

I love creating models and coming up with explicit structures I can play with.

It's hard to play basketball when nothing is inside of you.

Impossible is a word to be found only in the dictionary of fools.

I treat any scene the same - dialogue, action - you're still creating something in character. It's all acting, fighting.

In the beginning, the media was calling me a bad boy all the time because of the way I act and feel onstage. None of them have ever taken the time to get to know me when I climb offstage.

At first, there was a separation of clubs and sketch comedy. Now there's all kinds of comedy, making us one big happy family.
