Model Performance Analysis

Our system employs three different models for fire and smoke detection: a Custom Model, VGG16, and InceptionV3. Here's a comprehensive analysis of their performance:

Prediction Confidence Distribution

Prediction Confidence Distribution Distribution of prediction confidence scores across models. The InceptionV3 model shows the highest concentration of high-confidence predictions (0.9-1.0), followed by VGG16, while the Custom Model shows a more distributed confidence pattern.

Confusion Matrices
