🔍 What is Deep Learning?

Deep learning is a subset of machine learning inspired by the structure and function of the human brain. It uses neural networks to analyze large datasets and make predictions, classify objects, and even generate new content.

🔹 Key Components of Deep Learning:
✔️ Artificial Neural Networks (ANNs)
✔️ Convolutional Neural Networks (CNNs)
✔️ Recurrent Neural Networks (RNNs)
✔️ Deep Reinforcement Learning

🐍 Why Use Python for Deep Learning?

Python is the preferred language for deep learning because of its simplicity, flexibility, and rich ecosystem.

🛠️ Popular Python Libraries for Deep Learning:
✅ TensorFlow – Google’s open-source framework for deep learning
✅ Keras – High-level API that simplifies neural network building
✅ PyTorch – Facebook’s powerful deep learning framework
✅ Scikit-learn – Ideal for machine learning models
✅ NumPy & Pandas – Essential for data analysis

🧩 Key Concepts in Deep Learning

🔹 Neural Networks – Mimic the human brain’s structure to process data
