VSM, LSA, & SVD | Introduction to Text Analytics with R | Part 7

An overview of the Vector Space Model (VSM), Latent Semantic Analysis (LSA), and Singular Value Decomposition (SVD). This talk will cover: – The trade-offs of expanding the text analytics feature space with n-grams. – How bag-of-words representations map to the vector space model (VSM). – Usage of the dot product between document vectors as a proxy for correlation. – Latent semantic analysis (LSA) as a means to address the curse of dimensionality in text analytics. – How LSA is implemented using singular value decomposition (SVD). – Mapping new data into the lower dimensional SVD space.
