Introduction to Markov Chains - Part 1

[macki2006]

my ear is filled with BRAND A

[glmathgrant]

2:16 "Maybe people buy OJ. . ."

No. They don't buy him.

[WillWolfrick]

Very cool video! I was wondering if you can post something related to Markov Decision Process as it seems to be a very interesting topic. Since you teach really well it would be cool to see a video of yours related to this topic!

Great job!

[alexglew]

so far so good, onto video 2!

[preetcharan]

Mr. PatrikJMT very good of you by using THE MULTIPLICATION PRINCIPLE at 10:00.

Very rare authors use this principle to explain initial or distribution vector. But you are first video instructor to tell in a nice way to solve the confusing π with S.

Thanks

[Gauss156]

Thanks for the great video, PatrickJMT.

[formchoi2190]

love ur vids!!!!

[firedragoncow1234]

You're left handed--I'm sorry. Haha kidding... except not really.

Either way, thank you for the video! Awesome job!

[germyname]

Wasn't my intention to negatively criticize this video at all. This is an excellent video. I had just made a small observation on public speaking. Unfortunately I wasn't thinking and I posted my observation in the "comments" section instead of sending my recommendation to patrickJMT directly. Therefore my apologies to him for doing so in a public venue. Again, this is an excellent video and I found it very helpful (as I had stated before).

[leonardpaulson]

@germyname I get where you were coming from.

[HyyRisque]

HOW ARE YOU SO GOOD AT MATHS!!!! LOL please give me a tiny portion of your knowledge!

[Mischala]

I had about 3 lectures on this topic, This 12min video sums those 3 hours up very well, thank you, Patrick, for the free revision.

[germyname]

Excellent and informative video. From a public speaking perspective, please think about how often you use the word "Suppose" in the first few minutes. I found it very distracting. Otherwise, I thought the video was very helpful. Thanks.

[patrickJMT]

@germyname i will think about it and say it some extra times, just for you

[fwemail]

Both are incredibly typical examples of Americanism. One is unnecessarily critical to something he/she benefits for free. The other is resentful to any critism even if it may be constructive. Oh wait a minute, I am being critical too! LOL

[MrDavexmac]

@germyname That's how math teachers talk (and economics profs) get used to it. 

[yogabagaba93]

@germyname suppose you hate, i suppose you should f off suppose that

[yogabagaba93]

i have a really imporatn question. How come with the transition matrix 2 by 2 if you to T^2, T^3...etc. you will alsways get 1 when you add horizontally?

[yogabagaba93]

@germyname stop hating this guys so good

[jmulv17]

@germyname but he only said it 50 times

[aha1234]

good, thx



[KoalaBearWarrior]

For all the non-actuarial science guys .... At 10:59 when he is writing, then reason why you multiply 0.2 by 0.9 and 0.8 by 0.7 is because it means you bought the product and you've bought the product again OR you didn't buy the product and now you have. And (assuming independence) always means multiply :)

[kydkidd]

You are so cool, man. Really thank you.

[IFoundMyUsername]

It is like Bayesian theorem....maybe not.

[ludobichi]

Nice video. Thanks a lot for uploading it!

[xXMaGGoXx]

thanks for the video dude, especially the first part of this.

The second half of it is rather talking about tree diagramms though?

[Greenwithevil]

I love you man. Seriously. I go to NYU and have a final tomorrow on Stochastic Processes.

You are my cram-God.

[aliye89]

it is the most favorite teacher!

[kbilal89]

wonderful job, may God bless you for this!!!! :D

[TheAlibhangu]

your a modern day hero :)

[krajobrazOukwOeduOpl]

good job!

[nitekim01]

superr super thanks a million u are really good teacher

[saadamiens]

Please can you make more tutorials on Markov chain , thank you

[123MetalRules]

really nice video

[jormoria]

i watch porn first and then i watch this.this video is better than porn.

[shootkiss]

~12 min video save about 3 hour of time in understand such thing . A[12 , 3]

[warnick80]

this helped me alot too but is it possible to do a video on how to find the steady state vector using row reduction or eigenvalues and eigenvectors

[mugubasher]

Thanks, this helped me a lot,

[kepstein8888]

Thanks for these videos. What a great way to help people help themselves.

[zahamaraa]

thanks so thanks n congrats, u help me a lot with this item because i had to explain markov chains for my school

[Has564]

You are a great teacher. Thank you very much for making this video.

[cacgonzaga]

Google should create a system (through GoogleCheckout, perhaps) that allows users to make small donations to teachers like you. These donations could generate gains for teachers like you, similar those gains developers get with the AppleStore. Picking talent from all over the world, that could create a world class of super reinforcement teachers, available 24 hours a day to students around the world!

[Furuly]

Nice work man, keep posting more!

[ZeqBarboza]

very good!!!

[MoonHyounSeok]

excellent!!

[amirtaaki]

Sexiness factor of markov chain = 1.0

[michaill]

In initial state shouldn't brand A have 20% of all OJ users instead of 20% of the revenues as you say at 00:35?

[Kelsita0529ballerina]

You are fantastic! Thanks for helping me pass my finite final!

[aorusso]

The example is mathematically correct. Besides is impossible from a business point of view. If thera are a unique company, A', with the 80% of the market, you can expect retaliation after the first week. That converts your example in Game with Nash equilibria. I'm reformulating the problem with A' representing a set of companies with shares lower than 10% each, in which case, as I understand, the problem makes sense.

[lilrp76]

The transition diagram looks like a monkey. haha

[danubis077]

did anyone ever tell you you look like House from Fox House MD. Thats a compliment btw

and thanks?

[I3ui2n]

DUDE, your awesome =)

[Souliee]

cant wait for more! :D

[polos505]

Another awesome video. 5 stars.

[Mattprole]

I was going to go watch porn, but this distracted me.

[paulreider]

LOL

[mikesty]

This is porn.

[yogabagaba93]

@mikesty ewwwwwwww you are disgusting

[Gauss156]

@mikesty math porn. love it.

[mjay22]

it's a good thing you watch this i suppose - it'll be more useful. ;) i'd rather have sex in real life than watching porn anyway - it's more satisfying. right? ;)

[chamraj]

@Mattprole LOL!

[rsxdarkxsin]

@Mattprole

me too....

[yogabagaba93]

@Mattprole same! 

[iceboarderz]

How many markers have you gone through? =D

[Thisisnotmyrealname8]

What's a number?

[eedahl]

You construct a number using Peanos axioms. Then you introduce the rational numbers by formally introducing quotients. From there you can proceed with the completion of your choice constructing the reals from which the complex numbers C are produced by formally defining i=sqrt(-1). From this leaves you with an algebraically closed field, which means that all polynomial polynomial equations with coefficients in C has a root, and you're golden. I think that's a fairly accurate outline.

[Thisisnotmyrealname8]

Thanks, I'd have never gotten that by myself.

[GR1o6180339887498948]

@Thisisnotmyrealname8

An element in the complex field :)

[midnight9wanderer]

Patrick you are really shifting up a gear. This will help a lot with some of the stat. physics Im struggling with.

[sdfdsv]

I agree with Susan, this is a really cool topic, hope you keep uploading videos like this

[LordSusan]

May I ask when this is introduced? I find this interesting...
