How to interpret the output of LDA (discriminant analysis) in R

The typical implementation of the LDA technique requires that all the samples are available in advance. However, there are situations where the entire data set is not available and the input data are observed as a stream. In this case, it is desirable for the LDA feature extraction to have the ability to update the computed LDA features by observing the new samples without running the algorithm on the whole data set. For example, in many real-time applications such as mobile … WebApr 8, 2024 · 1. The LSA can be used for dimensionality reduction. We can reduce the vector size drastically from millions to thousands without losing any context or information. As a result, it reduces the computation power and the time taken to perform the computation. 2. The LSA can be used in search engines.
