This document provides a summary of Markov chains. It begins by defining stochastic processes and Markov chains. A Markov chain is a stochastic process where the probability of the next state depends only on the current state, not on the sequence of events that preceded it. The document discusses n-step transition probabilities, classification of states, and steady-state probabilities. It provides examples of Markov chains for cola purchases and camera store inventory to illustrate the concepts.
Markov chains are a very common model for systems that change probablistically over time. We show a few fun examples, define the objects, state the main theorems, and show how to find the steady-state vector.
This ppt includes the definition of the Markov process, Markov chain. Some real-life examples and applications. It also includes some of its advantages and limitations.

Introduction Stochastic Processes.
Markov Chains.
Chapman-Kolmogorov Equations
Classification of States

Dynamic Programming is a method for solving a complex problem by breaking it down into a collection of simpler subproblems, solving each of those subproblems just once, and storing their solutions using a memory-based data structure (array, map,etc).
Statistical simulation technique that provides approximate solution to problems expressed mathematically.
It utilize the sequence of random number to perform the simulation.

Supervised Hidden Markov Chains.
Here, we used the paper by Rabiner as a base for the presentation. Thus, we have the following three problems:
1.- How efficiently compute the probability given a model.
2.- Given an observation to which class it belongs
3.- How to find the parameters given data for training.
The first two follow Rabiner's explanation, but in the third one I used the Lagrange Multiplier Optimization because Rabiner lacks a clear explanation about how solving the issue.
—Stochastic processes have many useful applications
and are taught in several university programmers. In this paper
we are using stochastic process with complex concept on Markov
chains which uses a transition matrix to plot a transition diagram
and there are several examples which explains various type of
transition diagram. The concept behind this topic is simple and
easy to understand.

Part I. Read Sections #29.5 (Long-run properties of Markov Chains), #29.6 (First Passage
Times) of the attached, and write a summary report.
Note that the summary report has to be prepared on a word processor (e.g., MS Word), and it has
to be submitted through our class canvas system. Your report will be formatted with the
following traits:
The title page should include course title, student name, and the date.
There is no page limit but the article summary should be at least 2 pages long, single spaced
throughout.
Use a standard font (Times New Roman 12).
Use 1 inch margins for top, bottom, left, and right.
Use proper punctuation, spelling, and grammar.
All pages (with the exception of the title page) should be numbered.

Markov Chains
Chapter 16 focused on decision making in the face of uncertainty about one futureevent (learning the true state of nature). However, some decisions need to take into
account uncertainty about many future events. We now begin laying the groundwork for
decision making in this broader context.
In particular, this chapter presents probability models for processes that evolve over
time in a probabilistic manner. Such processes are called stochastic processes. After briefly
introducing general stochastic processes in the first section, the remainder of the chapter
focuses on a special kind called a Markov chain. Markov chains have the special prop-
erty that probabilities involving how the process will evolve in the future depend only on
the present state of the process, and so are independent of events in the past. Many
processes fit this description, so Markov chains provide an especially important kind of
probability model.
For example, Chap. 17 mentioned that continuous-time Markov chains (described in
Sec. 29.8) are used to formulate most of the basic models of queueing theory. Markov
chains also provided the foundation for the study of Markov decision models in Chap. 19.
There are a wide variety of other applications of Markov chains as well. A considerable
number of books and articles present some of these applications. One is Selected Refer-
ence 4, which describes applications in such diverse areas as the classification of
customers, DNA sequencing, the analysis of genetic networks, the estimation of sales
demand over time, and credit rating. Selected Reference 6 focuses on applications in fi-
nance and Selected Reference 3 describes applications for analyzing baseball strategy.
The list goes on and on, but let us turn now to a description of stochastic processes in
general and Markov chains in particular.

A stochastic process is defined as an indexed collection of random variables {Xt},
where the index t runs through a given set T. Often T is taken to be the set of non-

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

In the Adani-Hindenburg case, what is SEBI investigating.pptxAdani case
Adani SEBI investigation revealed that the latter had sought information from five foreign jurisdictions concerning the holdings of the firm’s foreign portfolio investors (FPIs) in relation to the alleged violations of the MPS Regulations. Nevertheless, the economic interest of the twelve FPIs based in tax haven jurisdictions still needs to be determined. The Adani Group firms classed these FPIs as public shareholders. According to Hindenburg, FPIs were used to get around regulatory standards.
2. Description Sometimes we are interested in how a random variable changes over time. The study of how a random variable evolves over time includes stochastic processes. An explanation of stochastic processes – in particular, a type of stochastic process known as a Markov chain is included. We begin by defining the concept of a stochastic process.
