Difference Between Machine Learning and Deep Learning

Machine Learning (ML) and Deep Learning (DL) are subsets of artificial intelligence that enable systems to learn from data. While deep learning is a specialized branch of machine learning, they differ in complexity, data requirements, and performance.

What is Machine Learning?

Machine learning is a method of teaching computers to learn patterns from data and make decisions without being explicitly programmed. It uses algorithms like decision trees, SVM, and regression.

# Example (conceptual)
from sklearn.linear_model import LinearRegression
model = LinearRegression()
model.fit(X, y)

What is Deep Learning?

Deep learning is a subset of machine learning that uses artificial neural networks with multiple layers to model complex patterns in large datasets.

# Example (conceptual)
from tensorflow import keras
model = keras.Sequential([
    keras.layers.Dense(64, activation='relu'),
    keras.layers.Dense(1)
])
