Essays Big Five Personality Predictor

This repository contains a PyTorch deployment bundle trained in AFLPS-ML-Psycholinguistics to predict Big Five personality dimensions from essay text.

Files

• pytorch_model.bin: PyTorch bundle containing model weights, TF-IDF vocabulary, IDF weights, threshold, and metrics.
• vectorizers/essays_tfidf.npz: portable TF-IDF artifact exported from the preprocessing environment.
• deployment.py: model architecture and preprocessing helpers.
• predict.py: command-line batch and single-text inference script.
• requirements.txt: minimal inference dependencies.

Local Inference

pip install -r requirements.txt
python predict.py pytorch_model.bin --text "Paste a new essay here."

For a CSV with a text column:

python predict.py pytorch_model.bin --input essays.csv --output predictions.csv

Output

The model returns probabilities and binary predictions for:

• O: Openness
• C: Conscientiousness
• E: Extraversion
• A: Agreeableness
• N: Neuroticism
