Module 2: Multilayer Neural Networks (The Brain)
📚 Module 2: Multilayer Neural Networks (MLP)
Course ID: DL-402
Subject: The Networked Brain
One Perceptron is simple. But what if we connect hundreds of them? This is where the magic happens. We call this a Neural Network.
🏗️ Step 1: The Three Layers (The “Team”)
- Input Layer (The Eyes): “Sees” the raw data.
- Hidden Layers (The Thinkers): Looks for patterns (lines, circles, shapes).
- Output Layer (The Decision): Makes the final choice (Cat or Dog).
🏗️ Step 2: Connections (The “Flow”)
Every neuron in one layer is connected to every neuron in the next. This is called a Dense Layer.
🧩 The Analogy: The Telephone Game
As information passes through the chain, it gets interpreted and refined until a final concept is formed.
🥅 Module 2 Review
- Layers: Input (Eyes), Hidden (Thinkers), Output (Decision).
- Dense Layer: Fully connected neurons.
- Hidden Patterns: How simple shapes become complex concepts.
:::tip Slow Learner Note The “Hidden” layers are called hidden because you don’t directly see the rules they learn. You only see what goes in and what comes out! :::
