Brain Made of Layers

Your brain has billions of neurons connected together.

Each neuron:

• Receives signals
• Processes them
• Sends to next neurons

Neural networks copy this idea!

The Structure

Input Layer → Hidden Layers → Output Layer
   📷           🧠🧠🧠          🏷️
  (raw data)   (processing)   (answer)

Example: Identifying a cat photo

• Input: Pixels
• Hidden: "I see fur... ears... whiskers..."
• Output: "It's a cat!" 🐱

How It Learns

1. Show it a cat photo, labeled "cat"
2. Network guesses: "dog?" ❌
3. Wrong! Adjust the connections
4. Show more examples
5. Eventually: "cat!" ✅

Repeat millions of times = smart network!

---

The Math

Each connection has a "weight" (importance).

Input × Weight = Signal to next neuron

Learning = adjusting weights until answers are right.

---

In One Sentence

Neural networks are layers of connected units that learn patterns by adjusting connection strengths based on examples.
