## Overview

This repository is a small collection of neural-network classification notebooks, not a reusable application or service. Its two documented workflows classify handwritten digits and bean-leaf conditions; the results presentation is a separate way to review example outcomes. The README describes notebook use and reported results, but no notebook source was available to verify internal model stages, data sources, or how results connect to the presentation.

Main entry points: [`NN_MNIST.ipynb`](https://github.com/mjunhaochen/ai-classification/blob/main/NN_MNIST.ipynb) (MNIST classifier), [`NN_Beans.ipynb`](https://github.com/mjunhaochen/ai-classification/blob/main/NN_Beans.ipynb) (Bean classifier), [`AI-results.pdf`](https://github.com/mjunhaochen/ai-classification/blob/main/AI-results.pdf) (Example results)
