Hotel Booking Cancellation Predictor

Predicts probability that a hotel booking will be cancelled (Sri Lankan hospitality context). The champion model is XGBoost; threshold based decisions currently use 0.35000000000000003 (see champion_meta.json).

Quickstart

from huggingface_hub import snapshot_download
import joblib, json, pandas as pd

local_dir = snapshot_download(repo_id="j2damax/hotel-cancel-model")
model = joblib.load(f"{local_dir}/champion_model.pkl")
preprocessor = joblib.load(f"{local_dir}/preprocessor.pkl")
meta = json.load(open(f"{local_dir}/champion_meta.json"))

sample = pd.DataFrame([{
    'lead_time': 45, 'arrival_month': 7, 'adults': 2, 'children': 0, 'adr': 110.0
}])

X = preprocessor.transform(sample)
proba = float(model.predict_proba(X)[:,1][0])
print('Cancellation probability:', round(proba, 4))

Notes

Model trained with stratified 5-fold CV; primary selection metric: F1; tie-breaker: ROC-AUC. Class imbalance handled via class weights.
