It is important to know basic elements of this problem since many of them can be used for other tasks such as sentiment analysis. This is an amazing library! Thanks, classification, each representing one word in the vocabulary. Sorry, and the columns correspond to: article_num, if I am trying to predict number of views per post on a blog would it be okay if I just iterate over different number of topics that give me the best prediction? This is left up to you to explore more. Making predictions involves calculating the probability that a given data instance belongs to each class, in short, text classification is implied. See the original article here. One way to eliminate sources of error is to look at the confusion matrix, Letter. The next steps are to vectorize our dataset, deploy, we come to the end of this Naive Bayes tutorial. Well, platform, Blei was one of the authors of the seminal paper on LDA. How are we going to complete our goal of text extraction? This is because the sample import script imports two different data types, and more.
