The features are encoded using a one-hot (aka ‘one-of-K’ or ‘dummy’) encoding scheme. This creates a binary column for each category and returns a sparse matrix or dense array (depending on the sparse_output parameter). By default, the encoder derives the categories based on the unique values in each feature.Page Number: 10. Question 1. A solution of a substance ‘X’ is used for white washing.

The model fits a Gaussian density to each class, assuming that all classes share the same covariance matrix. The fitted model can also be used to reduce the dimensionality of the input by projecting it to the most discriminative directions, using the transform method. New in version 0.17: LinearDiscriminantAnalysis.A chemical equation can be divided into two types: Balanced Chemical Equation and Unbalanced Chemical Equation. (a) Balanced Chemical Equation: A balanced chemical equation has the number of atoms of each element equal on both sides. Example: Zn + H 2 SO 4 → ZnSO 4 + H 2.
