AI Demos
Learn AI by touching it. Interactive demos used at our open campus events, published here.
The demos themselves are written in Japanese. Your browser should offer to translate them.
How machines learn
How a computer finds rules in data, starting from the foundations.
Measuring Error
Change how you measure error, and the right summary value changes with it.
Reading a Positive
A 99%-accurate test comes back positive. Your odds of being ill are nowhere near 99%.
The Reversal
Across 800 patients drug A wins. Split them by severity and drug B wins in both groups. Same numbers, opposite verdict.
The Overfitted Curve
Fit your data perfectly and you predict the next point worse. That is overfitting.
k-means Art from Your Photos
See how similar things group themselves, then reduce the colors in your own photo.
Learn Classification with Decision Trees
Watch a computer learn to judge using nothing but yes/no questions.
Ask the Neighbours
Things nearby are probably alike â that alone classifies. Same data as the decision tree.
Nim-Playing AI
Play an AI that was never taught the winning strategy â and watch it find one anyway.
Deciding under uncertainty
How to choose when the future is unknown â problems from management engineering.
The Newsvendor Problem
How many to stock each morning â and why average demand is the wrong answer.
How Many Tills
As utilisation nears 100%, waiting time does not rise in proportion. It explodes.
Which Order to Drive
Routing a delivery van: 20 stops means 6Ă10^16 possible tours. You cannot try them all, yet a near-shortest route takes an instant.
The Price War, Repeated
Both sides pick what pays, and both end up worse off â until the game repeats.
How information is represented
Predicting what comes next, making it shorter, keeping it intact â the information theory this lab works on.
Drawing the Next Word
Draw cards from boxes to build a sentence. Widen the context and nonsense turns fluent â then turns into plain copying.
How Far It Shrinks
Write frequent letters in fewer bits and the whole file shrinks. Open a ZIP and find it running inside Word and PDF.
How Much It Repairs
Channels flip bits â even inside your own RAM. Design your own code and see how many errors it can undo.
The Multiplication You Cannot Undo
Send a secret without ever sharing a key. Multiplying is instant; splitting the product back apart is not.
