Features

Classification Model Plotting

Display a classification model results visualization:

import pandas as pd
from matplotlib.colors import ListedColormap
from sklearn.linear_model import LogisticRegression
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler

from opengood.py_ml_plot import display_classification_plot

dataset = pd.read_csv("data.csv")
x = dataset.iloc[:, :-1].values
y = dataset.iloc[:, -1].values

x_train, _, y_train, y_test = train_test_split(x, y, test_size=0.2, random_state=0)

sc = StandardScaler()
x_train = sc.fit_transform(x_train)

classifier = LogisticRegression(random_state=0)
classifier.fit(x_train, y_train)

display_classification_plot(
    x_train,
    y_train,
    sc,
    classifier,
    ListedColormap(("salmon", "dodgerblue")),
    "Logistic Regression (Training Set)",
    "Age",
    "Estimated Salary",
)
