## Overview

This repository documents two notebook-based lottery prediction projects: Mega Millions and Powerball. Each uses historical draw data to prepare features, train a bidirectional LSTM, and generate predictions with a rolling window and post-processing. The README documents this workflow, but no notebook source excerpts were provided, so the relationships below reflect documented behavior rather than inspected implementation details.

Main entry points: [`MegaMillions.ipynb`](https://github.com/ahmad-alam/lottery-prediction/blob/main/MegaMillions.ipynb) (Mega Millions notebook), [`Powerball.ipynb`](https://github.com/ahmad-alam/lottery-prediction/blob/main/Powerball.ipynb) (Powerball notebook), [`datasets/megamillions.csv`](https://github.com/ahmad-alam/lottery-prediction/blob/main/datasets/megamillions.csv) (Mega Millions draws), [`datasets/powerball.csv`](https://github.com/ahmad-alam/lottery-prediction/blob/main/datasets/powerball.csv) (Powerball draws)
