🚀 Usage

You can load the model directly from Hugging Face Hub and run predictions:

import xgboost as xgb
from sentence_transformers import SentenceTransformer
from huggingface_hub import hf_hub_download

# -----------------------------
# 1. Download model from Hugging Face
# -----------------------------
REPO_ID = "mjpsm/Imani-xgb-model"
FILENAME = "Imani_xgb_model.json"

model_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME)

# -----------------------------
# 2. Load Model + Embedder
# -----------------------------
model = xgb.XGBRegressor()
model.load_model(model_path)

embedder = SentenceTransformer("all-mpnet-base-v2")

# -----------------------------
# 3. Example Prediction
# -----------------------------
text = "I reminded my cousin that storms always pass."
embedding = embedder.encode([text])
score = model.predict(embedding)[0]

print("Predicted Imani Score:", round(float(score), 3))
