## Overview

This repository is a research implementation for detecting AI-generated images in misinformation contexts. The principal workflow is to prepare or obtain image datasets, configure and run a classifier notebook for training or inference, and inspect its results. The documented alternatives are a foundation-backbone/MLP classifier and a two-branch foundation-plus-LBP/ResNet-18 classifier. Dataset-generation notebooks are named for several image-generation models. Notebook internals were not sampled, so links reflect README-described architecture and workflow rather than unverified cell-level calls.
