 A neural model for forecasting future outcomes of conversations (e.g., derailment into personal attacks) as they develop.
 Available as an interactive notebook: [full version (fine-tuning + inference)](https://colab.research.google.com/drive/1SH4iMEHdoH4IovN-b9QOSK4kG4DhAwmb) or [inference-only](https://colab.research.google.com/drive/1GvICZN0VwZQSWw3pJaEVY-EQGoO-L5lH).
