# 🤖 How an AI System Actually Works

In 5 minutes, you'll understand what an AI system is, how it learns, and how to test it.

## 🎯 You Are The AI

Not all buildings use energy the same way. Look at the clues for these 3 buildings, spot the pattern, then predict the mystery building's energy efficiency rating.

🏢
Year: 1965
Size: 11,150 m²
Climate: Cold
🔴 Low Efficiency
🏠
Year: 2018
Size: 2,790 m²
Climate: Moderate
🟢 High Efficiency
🏬
Year: 1990
Size: 7,430 m²
Climate: Hot
🟡 Medium Efficiency
Mystery Building
❓
Year: 1958
Size: 13,940 m²

Before you can build better AI systems, you need to understand what AI actually is.

Don't worry — we'll explain it in simple, everyday terms!

## 🎯 A Simple Definition

Artificial Intelligence (AI) is just a fancy name for:

A system that makes predictions based on patterns

## 📐 The Three-Part Formula

Every AI follows three steps. Watch it work:

### INPUT

Data goes in

→

### MODEL

AI processes it

⚙️
→

### OUTPUT

Prediction comes out

Every AI system follows this formula: data goes in, the model finds patterns, a prediction comes out.

## 🧠 How AI Learns

AI isn't programmed with answers. It trains on thousands of examples and gets better each round. Watch:

1. INPUT
EXAMPLES
→
2. MODEL
GUESSES
→
3. CHECK
ANSWER
→
4. ADJUST
SETTINGS
→
LEARNED
MODEL

Each round, the AI adjusts its internal settings to get better. It learns how much each feature matters.

## 🔬 Testing the AI

The AI trained on buildings. But how do we prove it actually learned?

We split the data!

📚
75% Training
We give the model these buildings to practice on. It studies them and learns the patterns.
→
🔒
25% Test
We hide these buildings from the model. Then we ask it to predict them — if it gets them right, it really learned!

Why test on hidden building data instead of the data it practiced on?

🔄

Training data is easier

🆕

## 🎮 Try It Yourself!

Use a simple AI model to predict building energy efficiency.
Adjust the inputs and see how the prediction changes!

1️⃣ INPUT: Adjust the Data
Year Built 1950
Floor Area (m²) 12,090
Climate Zone
2️⃣ MODEL: Process the Data
3️⃣ OUTPUT: See the Prediction

Click "Run AI Prediction" above to see the result

Predictions made: 0

🎯 Challenge: Can you find settings that produce a 🟢 High Efficiency building?

Quick check: What did the MODEL do?
