Ask what should change when the equation is manipulated, then let the visualization test that expectation.

Synthetic Data & Self-Improvement
Key to modern training: Phi, LLaMA 3, many models use synthetic data
\theta_{t+1} = \text{Train}(\theta_t, \text{Generate}(\theta_t, \text{Filter}))Selected Foundation Object
Keep the equation fixed; move through the evidence.
Models can teach themselves if we filter for correct answers
\theta_{t+1} = \text{Train}(\theta_t, \text{Generate}(\theta_t, \text{Filter}))Use the runnable panel, the key equation, and canonical papers as separate forms of evidence for the same object.
The useful learning product is the reusable mechanism you can carry into another model, paper, or engineering tradeoff.
Use prerequisites, dependents, and semantic links to repair the next gap without leaving the object behind.
Why It Matters for Modern Models
- Key to modern training: Phi, LLaMA 3, many models use synthetic data
- Enables training without human annotation at scale
- Data quality > quantity: careful curation beats raw scale
What Tutorials Skip
What is still poorly explained in textbooks and papers:
- Models can teach themselves if we filter for correct answers
- Synthetic data amplifies capabilities the model already has (via distillation)
- The "data wall" problem: we're running out of internet text, synthetics are the solution
Interactive Visualization
Core Math (Optional Deep Dive)
If you want intuition first, start with the key equation and the visualization. Come back here for the full walkthrough.
Synthetic data generation:
- Generate candidates:
- Filter for quality:
- Train on filtered data:
Self-improvement loop:
Phi-1 insight: Small model + high-quality synthetic data > Large model + web data
Quality filtering: use reward models, verifiers, or consistency checks.
