What Is TF-IDF In Text Feature Selection? In this informative video, we’ll dive into the concept of TF-IDF, a key method used in text feature selection. We’ll begin by explaining what TF-IDF stands for and how it helps in understanding the significance of words within documents. You’ll learn about the two main components: Term Frequency and Inverse Document Frequency, and how they work together to provide a numerical score for words based on their importance.

We’ll also discuss the practical applications of TF-IDF, including its role in search engines and document classification tasks such as spam detection and sentiment analysis. By transforming text data into numerical vectors, TF-IDF allows machine learning algorithms to analyze and process text effectively. This capability is essential for comparing documents and retrieving relevant information.
