So what do they want to know?

At this point, our robot has localized itself.

Here is our sequence. There's a couple of sunny days 5 in total a rainy day, 3 sunny days, 2 rainy days.

One of the viewers pointed out not incorrectly that one definition of return on asset so this whole video's going to be on return on asset that one definition of return on asset, and if you look it up on some of the finance sites or even some finance textbooks, they'll tell you it's net income over total assets.

So, here's another quiz.

Now, it may seem like we made a backwards step.

Here we had one probability to estimate.

We study again our die. You observe the following sequence 1, 2, 3, 2.

Recommended Settings

Recommended settings

Recommended Settings...

Supposed suicide.

So let me switch colors just to ease the monotony.

This one, this one, and one out here, and I put a little check marks underneath.

So 55 say A and 45 say B.

I just want to tell you what you've learned, because you did amazingly well.

W 0, where 0 is your iteration number, and then you up with it iteratively.

For example, for the prior probability, we found that 3 8 messages are spam.

Uh, when I started farming,

So this is a timely problem.

Stop estimating backup size

Simple extrapolation.

If you understood this, you understand probability, and you understand localization.

let me explain it to you.

We find that along the main diagonal our uncertainty has shrunk substantially.

I will now teach you about estimators.

It's just a faster way of saying

700 rads per shot. (Laughter)

Calculate Recommended Settings

Control estimates their descent at 100 meters an hour.

Estimated time of death? Coroner puts time of death somewhere between 10 and 1 last night.

We asked them to estimate their likelihood of experiencing different terrible events in their lives.

Attention. Inbound dradis contact, rated highly probable enemy fighter.

looks neutral.

Maybe it goes to 2 in 2010.

Estimated writing speed

You presume correctly.

...because we hope there are survivors

It's hours, people per hour.

Instead of doing this present value calculation for everything, and there's so much error involved anyway, in terms of just estimating earnings, people just give a rule of thumb.

Fixed zoom

Let's now dive in and understand how to use this cryptic name maximum likelihood estimator.

So a lot of people immediately will figure out the Price to

So in 2013 you'll be making 16.

Today, there are 2.3 million.
