Web13. jún 2024 · For example, when we look at row 1, we can see the vector in the probability column, which consists of [0.06936682704327157, 0.9306331729567284]. The first element in the vector represents the probability of class 0 (no heart attack), and the second element the probability of class 1 (heart attack). Web28. nov 2024 · Understanding the Spark ML K-Means algorithm Classification works by finding coordinates in n-dimensional space that most nearly separates this data. Think of this as a plane in 3D space: on one side are data points belonging to one cluster, and the others are on the other side. In this example, we have 12 data features (data points).
