So I've looked at about 70 of these.

And in most information boxes, there's data.

I think they all involve the same thing we can take small pieces of data and by putting them together, we can generate more value, we can do more exciting things with them.

The main new thing in Unit 3 was lists.

And then we introduced the hash table.

Now, once we've done that what I want you to do is grab a specific piece of data, from that JSON.

This is a KDF, a key derivation function that's built from HMAC.

Introduction

Extraction

Smooth extraction?

The subjects for the experiment were chosen at random.

The people for the experiment were chosen at random.

Criteria

No, not drugs. Not hypnosis. None of that.

Weapon.JSON in and will return a JavaScript object representing the JSON that it's parsed.

His toxin is derived from the organic compound found in our blue flowers.

Suppose the value we added brings us to here.

Now this time, I've written the tokens as plus and minus and not instead of the symbols, or . That's our choice we can do it either way we want.

I have the man who murdered Helen.

We are going to process them into ricin.

To the extraction chamber!

Computer, begin extraction!

Today, we do a case study.

Using computers, even though they're getting faster and better all the time, it's a challenge to deal with gigabytes of data, terabytes of data and extracting the relevant information.

It uses that exact same data to avoid collisions with other cars, bicycles, pedestrians, and so on.

And then the radiologist, together with the pathologist and sometimes the forensic scientist,

So this is really what's enabling us to deal with the explosion of data in medicine, together with some really nifty work in terms of algorithms compressing data, extracting the relevant information that people are doing research on.

I'm a Lance Armstrong fan, so I'll go ahead and I'll click on that, which reveals, for me, all the issues in which Lance Armstrong's been a part of.

Extract an essence from the bark of a tree.

I've already isolated the virus.

This is a lot of work. As we are going to see.

And here are samples from the unigram model.

Now we can select the keywords we're interested in, and the center pane displays the associated references from My Library.

And so these are going to be three values drawn from a Gaussian distribution with mean zero and variance or standard deviation equal to one.

I've been so locked up with this series of experiments, I'm afraid that...

Here are two of them.

Gladly. It's right there, above the extraction chamber.
