- Parameters
fit_intercept (boolean, default True) – Whether to calculate the intercept for this model
verbose (union type, not for optimizer, default False) –
Sets the verbosity amount
boolean
or integer
precompute (union type, default 'auto') –
Whether to use a precomputed Gram matrix to speed up calculations
array, not for optimizer of items : Any
or ‘auto’
n_nonzero_coefs (integer, >=500 for optimizer, <=501 for optimizer, uniform distribution, default 500) – Target number of non-zero coefficients
eps (float, >=0.001 for optimizer, <=0.1 for optimizer, loguniform distribution, default 2.220446049250313e-16) – The machine-precision regularization in the computation of the Cholesky diagonal factors
copy_X (boolean, default True) – If
True
, X will be copied; else, it may be overwritten.fit_path (boolean, default True) – If True the full path is stored in the
coef_path_
attributejitter (union type, not for optimizer, default None) –
Upper bound on a uniform noise parameter to be added to the y values, to satisfy the model’s assumption of one-at-a-time computations
float
or None
random_state (union type, not for optimizer, default None) –
The seed of the pseudo random number generator to use when shuffling the data
integer
or numpy.random.RandomState
or None
- fit(X, y=None, **fit_params)¶
Train the operator.
Note: The fit method is not available until this operator is trainable.
Once this method is available, it will have the following signature:
- Parameters
X (array of items : array of items : float) – Training data.
y (union type) –
Target values.
array of items : float
or array of items : array of items : float
Xy (Any, optional) – Xy = np.dot(X.T, y) that can be precomputed
- predict(X, **predict_params)¶
Make predictions.
Note: The predict method is not available until this operator is trained.
Once this method is available, it will have the following signature:
- Parameters
X (union type) –
Samples.
array of items : Any
or array of items : array of items : float
- Returns
result – Returns predicted values.
- Return type
array of items : float
