Graph based feature engineering
WebThis is particularly useful to relevance models, as it significantly reduce the feature engineering work on the knowledge graph. Insights extraction from the graph Additional knowledge can... WebThe approach extracts a single feature called graph Laplacian Fiedler number from the noise-contaminated acoustic sensor data, which is subsequently tracked in a statistical control chart. Using this approach, the onset of various types of flaws are detected with a false alarm rate less-than 2%.
