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 like to celebrate my life. I have a life that I'm really lucky to have, and so I want to make sure every minute counts and that I go on great vacations and I share my memories with people that I love and that will make me laugh and lalalalalala.

There's almost no way of doing importing honestly, because if you do you're at such a disadvantage competitively. So people spend huge amounts of effort getting around stupid laws and not paying taxes.

All terrorism is theater.

Any filmmaking, any film is a collaborative process. There's always a lot of people working on things together.

In the past, when I'd recorded during a break in a tour, it was so easy to sing, because I felt strong. Also, like so many new mothers, I wasn't getting a lot of sleep, and sleeping is such a huge part of being able to sing.

My mum told me that grown-ups don't like teenagers, which is the last thing you want to hear when you are one yourself!

Don't wallow in brainstorming. Time spent fiddling with a business plan or filling up whiteboards with ideas is time that you could spend actually launching your business and seeing if the idea floats. Launching gives you real, solid feedback, instead of the imaginary 'what if' scenarios dreamed up in a conference room.

The bigger the city is, the less infrastructure you need per capita.

Some forms of motor neuron disease are genetically linked, but I have no indication that my kind is. No other member of my family has had it. But I would be in favour of abortion if there was a high risk.

Being human means throwing your whole life on the scales of destiny when need be all the while rejoicing in every sunny day and every beautiful cloud.

Too afraid of plagiarising someone, so I stopped reading fiction in 1981.

It means a lot to defend my title.

When I first moved out to L.A., I was still 17. The deal with my dad was that I would be able to live out there if I were to treat my acting classes like college classes. So when I moved, that's all I did: trained and auditioned.

You have to hold onto your fantasy.

Men are generally more careful of the breed of their horses and dogs than of their children.

I like to think of myself as a humanitarian.

The music speaks for itself. You either like it or you don't, or you're somewhere in between. That doesn't change whether I'm in the band or not.

Am I a liberal or conservative? I'm neither. Like most Americans, I find politics very frustrating. Like most Americans, I'd like to hear from politicians the facts. That is what drives me.

Football is a great love because I was born into a family of players and therefore born into football. I'm fortunate to have a style of play that a lot of people like. It's a privilege to be able to do what I like best and in my own way, but I'm fortunate that people like it, and that motivates me even more.

I get terrified the first day I'm on a film set. I get nervous walking down a red carpet. I find making speeches the most terrifying thing in the world.

Im stronger than I thought I was. My favorite phrase has been This too shall pass. I now understand it really well.

It's important for moms to have alone time. However, that's the first thing that goes on a busy day. Fortunately for me, because of my job, I have to find the time to do it. At least that's the way my mind sees it. I have to exercise to be able to fit the clothes and book the jobs.

Productivity depends on many factors, including our workforce's knowledge and skills and the quantity and quality of the capital, technology, and infrastructure that they have to work with.

By the year 2040, the world's population is likely to increase by about 2 billion people, with also projected economic output will be up about 130 percent versus the year 2010.
