LSTM-based dengue outbreak early-warning system for Khartoum State, Sudan — built for conflict-affected, data-scarce environments.
# Dengue Intelligent Dashboard (DID)
**An LSTM-based early warning system for dengue outbreak prediction in conflict-affected, data-scarce environments — built for Khartoum State, Sudan.**

## The Problem
Dengue outbreaks in Sudan are difficult to forecast using conventional surveillance systems (EWARS, IDSR, DengueNet) because:
- Conflict has disrupted routine case reporting and health infrastructure
- Ground climate stations are sparse or non-functional
- Displacement patterns significantly alter transmission risk but are rarely incorporated into existing models
DID addresses these gaps by combining satellite climate data, displacement tracking, and epidemiological records into a single deep-learning forecasting pipeline designed to work *despite* missing or irregular data — a common reality in conflict settings.
## What Makes DID Different
| Challenge in Conflict Settings | DID's Approach |
|---|---|
| Missing/irregular case data | MICE imputation + Kalman smoothing |
| No reliable ground weather stations | NASA POWER, CHIRPS, and MODIS satellite data |
| Displacement-driven transmission risk | UNHCR/IOM displacement tracking as a model feature |
| Noisy, sparse sequences | LSTM Masking Layer to handle missing time steps directly |
| Systemic reporting bias | Bayesian hierarchical correction |

## Model & Methodology
- **Architecture:** LSTM (Long Short-Term Memory) network with a masking layer for irregular/missing sequences
- **Inputs:** Satellite climate data (rainfall, temperature, vegetation), flood extent, displacement data, geolocated case records
- **Preprocessing:** Multiple Imputation by Chained Equations (MICE), Kalman smoothing for noisy time series
- **Bias correction:** Bayesian hierarchical modeling to adjust for uneven reporting across regions
- **Primary evaluation metric:** Recall ≥ 0.90 (in outbreak early-warning, missing a true outbreak is far costli …
