Linear Algebra for Data Science
Topic modeling is a statistical technique used to uncover hidden thematic structures in a large collection of texts. It helps in identifying clusters of words that frequently appear together, allowing for the categorization and summarization of information without needing to read every document. This process can reveal insights into the main themes present in the data, making it valuable for various applications like data compression and dimensionality reduction, as well as solving linear systems and optimization problems.
