Building AI with Python
Introduction to AI with Python
Artificial Intelligence (AI) is transforming industries worldwide, and Python has emerged as the lingua franca of AI development. With its simple syntax and powerful libraries, Python makes AI accessible to everyone - from beginners to seasoned professionals.
Did you know? Python is used by 57% of data scientists and machine learning developers, making it the most popular language for AI.
Setting Up Your Python AI Environment
Before diving into AI, you'll need to set up your development environment:
# Install Python (3.7 or higher recommended)
# Download from python.org
# Install essential libraries
pip install numpy pandas matplotlib scikit-learn tensorflowYour First Neural Network with TensorFlow
Let's build a simple neural network to recognize handwritten digits (MNIST dataset):
import tensorflow as tf
from tensorflow import keras
# Load dataset
mnist = keras.datasets.mnist
(train_images, train_labels), (test_images, test_labels) = mnist.load_data()
# Normalize the images
train_images = train_images / 255.0
test_images = test_images / 255.0
# Build the model
model = keras.Sequential([
keras.layers.Flatten(input_shape=(28, 28)),
keras.layers.Dense(128, activation='relu'),
keras.layers.Dense(10)
])
# Compile and train
model.compile(optimizer='adam',
loss=tf.keras.losses.SparseCategoricalCrossentropy(from_logits=True),
metrics=['accuracy'])
model.fit(train_images, train_labels, epochs=10)Key Python Libraries for AI
