LCVC-Ensemble Brain Tumor MRI Classifier

This Space contains a research demonstration of LCVC-Ensemble (Leakage-Controlled Validation-Calibrated Multi-Backbone Ensemble) for four-class brain tumor MRI classification.

Classes

glioma, meningioma, notumor, pituitary

Test metrics from the leakage-aware evaluation protocol

• Accuracy: 0.9887640449438202
• Macro-F1: 0.9887621278421996
• Balanced accuracy: 0.9887638076313365
• Macro-AUC OVR: 0.9997131229291261

Ensemble

The app loads 5 selected checkpoints and performs weighted averaging of temperature-scaled softmax probabilities.

Intended use

Research and educational demonstration only.
