Artificial Intelligence (AI) has become a dominant field in technology today. In this tutorial for building AI applications in Python, we will take a step-by-step approach to show you how to create amazing AI solutions using the Python programming language.
Getting Started with AI in Python
Python is an excellent choice for AI development due to its simplicity and the availability of powerful libraries. To get started, you’ll need to have Python installed on your machine along with essential libraries like numpy, pandas, and scikit-learn. You can install these libraries using pip:
pip install numpy pandas scikit-learnBuilding Your First AI Model
Let’s create a simple Linear Regression model using the scikit-learn library. This model will predict house prices based on a dataset.
import numpy as np
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
# Load dataset
data = pd.read_csv('house_prices.csv')
X = data[['size', 'bedrooms']]
y = data['price']
# Split the data into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Create the model
model = LinearRegression()
model.fit(X_train, y_train)
# Make predictions
predictions = model.predict(X_test)
