Welcome to the Deep Learning Fundamentals guide! 🌍🧠 This resource is designed to help you understand the core concepts of deep learning, from neural networks to training techniques. Let's dive in!

What is Deep Learning? 🤔

Deep learning is a subset of machine learning that uses neural networks with multiple layers to model complex patterns. Unlike traditional machine learning, it automatically learns features from raw data.

Key Concepts 🔍

  • Neurons & Layers
    The building blocks of neural networks. Each neuron applies a weighted sum and activation function to its inputs.

  • Activation Functions
    Functions like ReLU, Sigmoid, and Tanh introduce non-linearity. For example: 

    def ReLU(x):
    return max(0, x)

  • Loss Functions
    Measure model performance. Common ones include Mean Squared Error (MSE) and Cross-Entropy.
