It accepts the … WebTarget array¶. In addition to the feature matrix X, we also generally work with a label or target array, which by convention we will usually call y.The target array is usually one dimensional, with length n_samples, and is generally contained in a NumPy array or Pandas Series.The target array may have continuous numerical values, or discrete classes/labels. WebSupervised learning: predicting an output variable from high-dimensional observations¶. The problem solved in supervised learning. Supervised learning consists in learning the link between two datasets: the observed data X and an external variable y that we are trying to predict, usually called “target” or “labels”. Most often, y is a 1D array of length n_samples. shropshire key facts
