# 🔔 Notification Bad-Timing Detector — Interactive Demo

**Should you send that push notification right now?**

This Space provides an interactive demo for predicting the probability that the current moment is a **bad time** to interrupt a user with a push notification.

## Features
- 🎛️ **21 input signals** across 4 categories: time, battery, activity, notifications
- ⚡ **5 preset scenarios** to quickly test common situations
- 📊 **Visual probability gauge** with color-coded recommendations
- 🎯 **Calibrated probabilities** via isotonic regression

## Model
- **Architecture**: LightGBM gradient boosted trees with isotonic calibration
- **Performance**: ROC-AUC 0.834, F1 0.777, Accuracy 75.8%
- **Training**: 100K synthetic samples based on [C-3PO](https://arxiv.org/abs/1803.00458) research
