WebApr 19, 2024 · At the bare minimum, the ROC curve of a model has to be above the black dotted line (which shows the model at least performs better than a random guess). Secondly, the performance of the model is measured by 2 parameters: True Positive (TP) rate: a.k.a. recall False Positive (FP) rate: a.k.a. probability of a false alarm WebClustering algorithms seek to learn, from the properties of the data, an optimal division or discrete labeling of groups of points. Many clustering algorithms are available in Scikit-Learn and elsewhere, but perhaps the simplest to understand is an algorithm known as k-means clustering, which is implemented in sklearn.cluster.KMeans.
