How can I integrate NumPy with scikit-learn for data analysis?

You can use NumPy to handle numerical data and perform operations, while scikit-learn provides tools for machine learning. For example, you can use NumPy arrays as input for scikit-learn models.

Can you show me a simple example of using NumPy with scikit-learn?

Sure! First, you can create a NumPy array with your data. Then, you can use scikit-learn's train_test_split to split the data into training and testing sets. Here's a quick code snippet:

import numpy as np
from sklearn.model_selection import train_test_split

# Create a NumPy array
X = np.array([[1, 2], [3, 4], [5, 6], [7, 8]])
Y = np.array([0, 1, 0, 1])

# Split the data
X_train, X_test, Y_train, Y_test = train_test_split(X, Y, test_size=0.2)

What kind of models can I use with this data?

You can use various models from scikit-learn, such as LogisticRegression, DecisionTreeClassifier, or RandomForestClassifier. Just fit the model using your training data like this:

from sklearn.linear_model import LogisticRegression

model = LogisticRegression()
model.fit(X_train, Y_train)
