Web2.1.1. Input data¶. In order to train a model, you need two array-like objects, X and y. X should be a 2D array-like of shape (n_samples, n_features), where n_samples is the number of points of your dataset and n_features is the number of attributes describing each point. y should be a 1D array-like of shape (n_samples,), containing for each point in X the class it … Web2-D embedding has loss 0.124191, and 3-D embedding has loss 0.0990884. As expected, the 3-D embedding has lower loss. View the embeddings. Use RGB colors [1 0 0], [0 1 0], and [0 0 1].. For the 3-D plot, convert the species to numeric values using the categorical command, then convert the numeric values to RGB colors using the sparse function as follows.
