Baunsgaard opened a new pull request #1124: URL: https://github.com/apache/systemds/pull/1124
Adds a predict function for PCA and an inverse function. The predict is for unseen data, that the PCA was not trained for just like our other predict functions for other algorithms The Inverse is to apply on an PCA reduced dataset, to reconstruct an approximation of the original data. The second is added because PCA can be considered a classic Lossy compression algorithm, that gives an smaller, approximated matrix of the original data. It also allows us to calculate how well the given PCA fits to the dateset. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
