To show what a Markov Chain looks like, we can use adigraph, where each node is a state (with a label or associated data), and the weight of the edge that goes from nodeato nodebis theprobability of jumping from stateato stateb. Here’s an example, modelling the weather as a Markov...
To prove that Gibbs sampling works, however, it's better to take a different route. If a Markov chain implemented by a sampling algorithm has distribution pp as invariant distribution, and is irreducible and aperiodic, then the Markov chain will converge to that distribution (Tierney, 1994). ...

As expected, the rows sum to zero. I have rounded the values to three decimal places, colored the backgrounds according to the rounded values, and desaturated those colors to reflect the magnitudes of the entries (so that grayish entries are small). The patterns clearly stand out. ...
3. How to use cProfile ? cProfile provides a simple run() function which is sufficient for most cases. The syntax is cProfile.run(statement, filename=None, sort=-1). You can pass python code or a function name that you want to profile as a string to the statement argument. If you...
As they were pre-trained on Masked Language Modelling, you can get them to "fill in the blanks". Unfortunately, they quickly become incoherent when several blanks appear together. Nevertheless, using MCMC (Markov Chain Monte Carlo) methods, it is possible to get good results. If you attempt ...
At this stage, we find that most firms in Taiwan need to improve their respective financial credibility. Fourth, we apply DEA credibility scores to the Markov chain model. Finally, we construct transition matrices to observe the transition process of the financial efficiency of the firms. The ...
