Overview
Explore advanced text analytics techniques in R with this comprehensive tutorial on Singular Value Decomposition (SVD). Learn to implement truncated SVD using the irlba package and project TF-IDF document vectors into the SVD semantic space for Latent Semantic Analysis (LSA). Compare model performance between a single decision tree and random forest, and discover how to fine-tune random forest models using the caret package. Access the accompanying data and R code to practice these techniques hands-on. Gain valuable insights into text analytics and machine learning applications for natural language processing tasks.
