Wildfire Classifier - 1INF52 Project

Repository with our Deep Learning approach for Wildfire Detection on the FLAME dataset.

We train three convolutional neural network (CNN) models (DenseNet, ResNet, Xception) via transfer learning, then combine them in an ensemble. Our final model is intended to detect Fire vs. No Fire in UAV images.

This project was developed as the final work for PUCP's 1INF52.

Pipeline

1. Data Preprocessing: resize and augment the FLAME dataset images.
2. Model Training:
   • train each CNN individually with Keras Tuner-optimized hyperparameters
   • hyperparameters (example from final run):
     • Xception: 25 unfrozen layers, 0.45 dropout, 0.001 L2, LR=0.00541
     • DenseNet: 20 unfrozen layers, 0.35 dropout, 0.001 L2, LR=0.00147
     • ResNet: 45 unfrozen layers, 0.40 dropout, 0.0005 L2, LR=0.00093
3. Ensemble: merge each model’s predictions via simple averaging
4. Evaluation: compute accuracy, F1-score, confusion matrix, and ROC-AUC on test set

To run the pipeline:

chmod +x ./scripts/run.sh
./scripts/run.sh

Web App and Hugging Face

We created a minimal FastAPI web application where one can upload an image and see if the model detects fire.

Trained models are also available on Hugging Face.
