Think of it as finding the main trends in a cloud of data points. These directions are called principal components. LDA, similar to PCA, is useful for classification tasks in datasets with labeled categories. It works by finding the best ways to separate different groups in the data, like ...
Latent Dirichlet allocation (LDA)—not to be confused withlinear discriminant analysisin machine learning—is a Bayesian approach to topic modeling. Simply put, LDA is a conditional, probabilistic form of topic modeling. Topic modeling is anatural language processing(NLP) technique that appliesunsupervi...
What's so good about this layered approach? It means people who write applications don't have to come up with all the code for controlling the computer's most basic functions—things like writing information to thehard driveor figuring out how themouseis moving; all that's done by the ope...

Topic modeling is a frequently used approach to discover hidden semantic patterns portrayed by a text corpus and automatically identify topics that exist inside it. Namely, it’s a type of statistical modeling that leverages unsupervised machine learning to analyze and identify clusters or groups of ...

Our evidence suggests that the newspapers shift the slant in their own local content, where direct copy-pasting from the TV channels is not possible (since the latter are nationally-oriented). Moreover, the exposure to the TV channels leads to a polarization of local news, where outlets that...
Latent Dirichlet allocation (LDA)—not to be confused withlinear discriminant analysis—is a probabilistic topic modeling algorithm. This means it generates topics, classifying words and documents among these topics, according to probability distributions. Using the document-term matrix, the LDA algorithm...
