How AI Detects Patterns

🔢

Sequences

AI finds rules in ordered data. Arithmetic, geometric, Fibonacci — recognising rules is the first step in prediction.

🚨

Anomaly Detection

Find the odd one out! AI learns what "normal" looks like, then flags anything that deviates significantly.

📈

Correlation

When two things move together, they're correlated. AI uses correlation to discover hidden relationships in data.

🔮

Prediction

Once the pattern is found, AI can predict what comes next — the basis of weather forecasting, stock prediction, and more!

Welcome to Pattern Hunter! 🔎 AI detects patterns in data to make predictions. First, let's tackle number sequences. Look at the visible numbers, spot the rule, and predict the hidden value. These are the same patterns AI uses to forecast stock prices and weather!

How to spot rules:
• Try subtracting consecutive terms
• Try dividing consecutive terms
• Look for squares, cubes
• Add previous two terms

Now spot the odd one out! 🚨 One value in each series doesn't follow the pattern. This is exactly what AI fraud detectors do — they learn the normal pattern of your spending, then flag any transaction that looks unusual. Click the anomaly!

Step 2 — Anomaly Detection

Click the value that doesn't belong:

Find the value that breaks the pattern. Look for the number that's too big, too small, or doesn't fit the rule.

When two variables move together, they're correlated! 📈 Click a dataset to see the scatter plot. A straight line = strong correlation. A cloud = no correlation. Positive correlation goes up-right; negative goes down-right. Can you guess the correlation strength?

Guess the r value:
r = 1.0: Perfect positive
r = 0.8: Strong positive
r = 0.3: Weak positive
r = 0.0: No correlation
r = -0.8: Strong negative

Key Concepts Mastered

Sequence

🔢 Ordered Patterns

A series with a mathematical rule. Arithmetic (add), Geometric (multiply), Fibonacci (sum previous two).

Anomaly

🚨 The Odd One Out

A data point that deviates significantly from the pattern. Used in fraud detection, quality control, and medical diagnosis.

Correlation

📈 Moving Together

When two variables change together. Pearson r measures this — from -1 (perfect negative) to +1 (perfect positive).

Causation ≠ Correlation

⚠️ Big Mistake

Ice cream sales and drowning both rise in summer — correlated, but neither causes the other. A common AI trap!

Prediction

🔮 Using Patterns

Once you know the rule, predict future values. Time series forecasting (stock prices, weather) all starts with pattern detection.

Noise

📡 Real Data is Messy

Real data always has noise — random variation. AI must find the pattern despite the noise, not just memorise it.

Learning objective: Spot the pattern a simplified model is learning as it sees more labelled examples.

What this simplifies: Patterns are deliberately simple and visual; real pattern recognition often involves far subtler statistical signal.

Privacy: No learner input leaves the device.

Teacher prompt: Ask the class why this simulation might mislead someone who takes it too literally.

Reflect: What is one thing this activity showed you that you did not expect?
