⚾ MLB Live Game Duration XGBoost Predictor

This repository contains an XGBoost regression model trained to predict the total expected duration (in minutes) of live Major League Baseball (MLB) games based on real-time pitch-by-pitch game state.

📊 Model Details

Model Type: XGBoost Regressor (XGBRegressor)
Format: Native XGBoost JSON (xgb_live_model.json)
Task: Tabular Regression (tabular-regression)
Target Variable: final_game_minutes (Total game duration in minutes)

🚀 How to Load & Use in Python

python

import xgboost as xgb
import pandas as pd
from huggingface_hub import hf_hub_download

# 1. Download the JSON model file from Hugging Face Hub
model_path = hf_hub_download(
    repo_id="mkly/mlb-game-duration-xgboost", 
    filename="xgb_live_model.json"
)

# 2. Load into XGBRegressor
model = xgb.XGBRegressor()
model.load_model(model_path)

# 3. Make predictions on a game state DataFrame
# sample_df = pd.DataFrame([{ "inning": 5, "outs_when_up": 1, ... }])
# predicted_minutes = model.predict(sample_df)[0]
# print(f"Predicted Total Duration: {predicted_minutes:.1f} minutes")
