vastorbit.machine_learning.vast.linear_model.PLSRegression.get_attributes

PLSRegression.get_attributes(attr_name: str | None = None) → Any

Returns the model attributes.

Parameters:

attr_name (str, optional) – Attribute name.

Returns:

model attribute.

Return type:

Any

Examples

We import vastorbit:

import vastorbit as vo

For this example, we will use the winequality dataset.

import vastorbit.datasets as vod

data = vod.load_winequality()

Rows: 1-100 | Columns: 14

Divide your dataset into training and testing subsets.

data = vod.load_winequality()
train, test = data.train_test_split(test_size = 0.2)

Let’s import the model:

from vastorbit.machine_learning.vast import LinearRegression

Then we can create the model:

model = LinearRegression(
    tol = 1e-6,
    fit_intercept = True,
)

We can now fit the model:

model.fit(
    train,
    [
        "fixed_acidity",
        "volatile_acidity",
        "citric_acid",
        "residual_sugar",
        "chlorides",
        "density",
    ],
    "quality",
    test,
)

We can easily get the model attributes:

model.get_attributes()

To access a specific attribute:

model.get_attributes('coef_')

Important

For this example, a specific model is utilized, and it may not correspond exactly to the model you are working with. To see a comprehensive example specific to your class of interest, please refer to that particular class.
