The Architecture of Intelligence, a free technology course on Tomo

The Architecture of Intelligence

Go beneath the interface to explore the mathematical engines and data structures that allow machines to predict, reason, and generate. Learn how simple patterns scale into the complex behaviors of modern AI.

Like Duolingo, but for The Architecture of Intelligence. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 26 levels across 3 sections, about 52 minutes end to end, roughly 10 days at five minutes a day. It moves through Foundations of Machine Learning, Processing Language and Context, and Training and Refinement. It assumes you already know the basics.

What you'll learn

Key ideas in The Architecture of Intelligence

  • Weights act like volume knobs for specific pieces of information.
  • A higher weight means an input has a stronger pull on the final result.
  • A weight of zero means the input is ignored regardless of its value.
  • Changing a weight directly scales how much an input contributes.
  • Learning happens by fine-tuning weights to match correct outcomes.
  • How weights determine the relative importance of different data points in a decision
  • Weights are variables that the system can shift to prioritize better data.
  • The relationship between weight adjustments and the resulting neuron output
  • Whether weights are static or adjustable to improve accuracy
  • The error signal shows if the guess was too high or too low
  • A guess must happen before an error can be measured
  • The system uses the gap to nudge its internal settings toward the truth
  • Settings are only updated after the error is calculated
  • The error acts as a guide or compass for the system
  • Without a target to compare against, the system cannot know which way to change
  • How the system uses the error signal to determine the direction of change
