then the Dirichlet distribution is just like a jar of dices. Each time you reach in (which we call "sampling"), you get a new dice. In the paper example, before
not many papers or blogs have covered this new algorithm too much despite its potential. The API is not completely well documented yet, although you can see its example from its source code on itsGithub. In its documentation, it gives an example of deriving topics from...

In LDA, a document may contain several different topics, each with their own related terms. The algorithm uses a probabilistic model for detecting the number of topics specified and extracting their related keywords. For example, a document may contain topics that could be classified as beach-rela...
Latent Dirichlet Allocation (LDA) is an example of a probabilistic topic model. What this exactly means, you'll learn in the following sections: you'll first come to understand how LDA starts from a bag-of-words description to represent the different documents. Then, you'll see how these ...
(LDA), a topic model for text or other discrete data. LDA allows you to analyze of corpus, and extract the topics that combined to form its documents. For example, click here to see the topics estimated from a small corpus of Associated Press documents. LDA is fully described in Blei ...

Creating LDA Mallet Model with Gensim - Learn how to create a Latent Dirichlet Allocation (LDA) model using the Mallet wrapper in Gensim. Step-by-step instructions and code examples included.
Bayesian inference is used elsewhere in computer science and it is the base of bots for example to create a filter against spam. Training a search engine algorithm in the same manner may be more effective than using a preset code. Citation (Griffiths and Steyver): ...
