SimulatorX Lab

An exploratory interactive surface for thinking through assumptions, evidence, and system behaviour.

Use boundary

SimulatorX is an educational scenario tool. It is not a clinical, public-health, policy, forecasting, or operational decision system, and it does not represent institutional adoption or validated outcomes. Every case in Inside the Model is synthetic.

Inside the Model

Two ways of predicting the same thing, a Bayesian network and a small neural network, watched from the inside. The question is never which one is smarter. It is what each one calculates, what it assumes, and what evidence would justify trusting it.

Resample the cases. Which blackout rate can move?

Every dot represents one synthetic case. The arrangement is illustrative, not a physical map.

4,096 synthetic cases · amber = blackout · cyan = normal

4,096 synthetic mini-grid cases, 37.2% of which are expected to end in a blackout.

Every dot is one simulated mini-grid on one day. Each view follows these sampled cases. Resampling draws a fresh sample; Drift changes their simulated conditions. Pick a view, or let it play.

Even a perfect model calls this share of cases wrong at a 50% threshold, because the world is random.

World minigrid-demo-001. All data is synthetic: no rate here describes any real grid. Sampling, the train/test split, weight initialisation and the bootstrap each use their own random stream, and animation uses none of them. Learning curves use 20 independent training pools and initialisations, with nested sample sizes within each pool. Share links preserve the experiment configuration, not a history of your actions.
