This RoBERTa-based model ("MindMiner") can classify the degree of mind perception in English language text in 2 classes:

- high mind perception 👩
- low mind perception 🤖

The model was fine-tuned on 997 manually annotated open-ended survey responses. 
The hold-out accuracy is 75.5% (vs. a balanced 50% random-chance baseline).
