Data for fire detection

What synthetic fire data can and cannot do. We checked the evidence

Synthetic data is sold with big promises. Before we sell any, we wanted to know what the published evidence actually supports. Here is what we found.

A note on the numbers below: mAP (mean average precision) is the standard score for object detectors. It measures how accurately and how completely a model finds and outlines objects, on a scale from 0 to 100 (or 0 to 1). Higher is better.

What it can do

What it cannot do

What that means for how we work

Three conclusions shaped our offer:

We would rather show a small, measured improvement on your data than a large number on ours.

What would you need to see in a pilot to trust synthetic data in your fire model?

Questions and answers

Can synthetic data replace real fire footage?

No. Published results show models trained on synthetic images alone perform clearly worse than models trained on real data. Synthetic data works as a supplement.

How much does synthetic data improve fire detection?

It depends on quality and filtering. Reported gains range from under one mAP point (DetectiumFire, mixed real and synthetic) to a much larger jump in a forest smoke study with filtered synthetic images (MFGDiffusion).

What is mAP?

Mean average precision, the standard score for object detectors. It combines how many objects a model finds and how precisely it outlines them.

How does a pilot work?

You keep a frozen test set of your own real footage. We generate data aimed at the errors your model makes today, you retrain, and we compare results on the same test set before and after.

Test it on your own model

A pilot targets the errors your model makes today and measures the result on your own test set.
