The model learns normal land conditions without labels, then flags burn signatures by comparing latent embeddings from paired dates. Across five Sudanese case studies the system detected fires in 24‑30 hours when clouds allowed observation. It outperformed cosine distance, change vector analysis and IR-MAD on precision, recall, F1 and AUPRC, even though the dataset was heavily skewed toward non‑fire pixels. Adding extra spectral bands or longer time series gave only marginal gains, confirming the lightweight setup is sufficient for near‑real‑time monitoring.\n\nFor humanitarian actors and analysts, the speed and low data demand mean daily watchlists can be generated without waiting for custom satellites or manual labeling. That could tighten response windows in conflict zones where fire often signals raids, scorched‑earth tactics or civilian displacement.\n\nThe result is not a panacea—cloud cover still blocks observations—but it shows a practical path for affordable, automated conflict surveillance that rivals older, more complex algorithms.","[\"satellite-imagery\",\"conflict-monitoring\",\"deep-learning\"]","2026-06-16T04:00:00.000Z","2026-06-17T04:38:42.826Z","2026-06-17T04:38:45.732Z","published",null,[],[25,26,27],"satellite-imagery","conflict-monitoring","deep-learning",[29],{"name":30,"url":31},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2512.07925",0]
