Since many of you are asking about the calculation of left eigenvector (π)...Here are the equations: from πA = π 0.2x + 0.3y + 0.5z = x 0.6x=y 0.2x+0.7y+0.5z=z from π[1]+π[2]+π[3] = 1 x+y+z=1

Hey, can you also tell how to code moving from one state to another based on probability? Like you did a random probability walk, how did the code decide which state to go to using probability.

This is sooo easy to understand. I took atleast a month to learn this about 25 yrs back for my masters thesis work when I first learnt this subject. Now, I thought of revisiting this topic for my daughter's higher secondary project. 25 years have really brought a topic from masters to secondary school level and months of learning to a few minutes of a well prepared video. Thanks to your channel, KZread, Internet and technology in general. 🙏

Sorry I missed all your comments. Markov Chains is one of the IA (Internal Assessment) topics to choose from for the HL (Higher level ?) Mathematics for IB (International Baccalaureate Diploma) programme ( which is higher secondary school level - Year 11 and Year 12) in Singapore. You can Google to find the details with the above information.

Thanks dude. It takes a whole nother level of intelligence to be able to break down a concept like this so anyone can understand it. I'm learning markov chains in class right now and when the professor teaches it it literally looks like an alien language to me, i almost broke down because i might fail the class. but im going to watch all ur videos and itll help me a lot.

This is a lifesaver. I started a stochastics class last week with an almost nonexistent background in probability. I was completely troubled at first but after watching this video and reading through some course material, I can actually understand the exercises. Thank you.

Mate, that is a good explanation! The only problem is that now I AM HUNGRY:)

While i was trying to understand this i avoided complex terms the best i can but with this video i have no need to try avoiding it because of the thorough explanation typing this 2 years later the "whats up people of the future" really got me

I was trying to understand Evolution algebras and for that I needed idea of Markov chains. Beautifully explained. Thank you so much.

Omg man this is such a great explanation. Loved the presentation, the animation and everything about it. Keep going!

Jeez, if my professor had introduced Markov chains like this instead of spending multiple lectures talking about Google's page-rank system without any goal in mind, I would've saved myself a lot of confusion. Thank you!

Note for my future revision. Markov Chain models a system that changes its status. One important rule: the next status of the system only depends on its current status. Status = serve pizza, serve burger or serve hotdog = x, y, z = Connected, Disconnected, Terminated, Active Markov chain can be drawn as a state diagram. Or written as a transition matrix. State diagram represents all possible status and associated probabilities. Transition matrix = represent the state diagram = probability from one state to another = A At equilibrium, the probabilities of the next status doesn't change any more. The probability of state at equilibrium = Stationary Distribution. Let's call such equilibrium probability π. Aπ = π π = Eigenvector of the matrix = Probabilities of each status the system could be in, assuming equilibrium stage. Using two equations: A) Aπ = π B) sum of probability is 1, we can work out the value of π, i.e. the equilibrium probability Alternatively, run a simulation. A: Do all Markov Chain have a equilibrium state? Q: Don't know... Need to study more to find out... Q: Can I use Subscriber Status to as the hidden state? A: Yes. But if the status is known, then it's better to use it as the Observation states. Q: Can I "model" next status to be only depending on the current status? But then the next status actually also depend on the previous status, this seems contradictory. A: Yes, I can. At per state level, the next status only depends on the current status. But the at the system level and at equilibrium, it "depends" on both the current and the previous state, because the current states had been "affected" by the previous states.

hii, maybe if you still need the answer. You can prove that an ergodic Markov chain, so a chain where all states communicate with each other and it’s aperiodic (gcd is 1) always has an equilibrium state.

Hello, Thanks for the wonderful explanation. I have a naive question though, how did we arrive at the adjacency matrix and directed graph with probabilities in the first place? Is it from observations or domain knowledge(in this case, will restaurant give us the probabilities)?

Yes yes we want more with such interesting examples

Very good explanation with clarity. It will be greatly appreciated if you could include the script of these videos.

Can you convert an adjacency matric to a transition matrix? I have a 5x5 adjacency matrix with some numbers larger than 1 (due to multiple connections between states).

Informative and super clear!!! Thx!

"Please pause the video if you need a moment to convince yourself" What kind of 3blue1brown is that?!

Thank you only one thing I didn't get after πA = π and sum of probability is 1, how do we calculate the stationary state as π =[25/71 15/ 71 31/71 ] ?

For a general problem, how do you get A (or know the probabilities going from one state to another?) I see that you assumed values for each arrow, but for a different problem, I don't know where to get such values.

I really find it very interesting to learn from you. So can you make videos on TAR and STAR model also?

Great video! A quick question and I apologize if someone already asked it: Intuitively, I would assume that the probability of any given state is simply the sum of the probabilities for that state divided by the sum of the probabilities for all states. For example, the probability for pizza is 0.2, because 0.6/3.0. The answers you get from the pi calculation and the random walk are very close to this, but not exact. What gives?

Perfect explanation, thanks!
