# 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.

## Medical disclaimer

This is **not a medical device**. It must not be used for diagnosis, treatment, triage, or clinical decision-making.

## Reproducibility note

The ensemble was selected using validation Macro-F1 only. Test labels were used only for final reporting after model selection.
