cave.analyzer.feature_clustering module

class cave.analyzer.feature_clustering.FeatureClustering(runscontainer)[source]

Bases: cave.analyzer.base_analyzer.BaseAnalyzer

Clustering instances in 2d; the color encodes the cluster assigned to each cluster. Similar to ISAC, we use a k-means to cluster the instances in the feature space. As pre-processing, we use standard scaling and a PCA to 2 dimensions. To guess the number of clusters, we use the silhouette score on the range of 2 to 12 in the number of clusters

runscontainer: RunsContainer contains all important information about the configurator runs

Depending on analysis, this creates jupyter-notebook compatible output.
