<h1>GDSC: PwnAI Image Classifier Demo</h1>
"""
description = r"""
<p>PwnAI is an educational event that explores adversarial machine learning. It aims to help students learn about LLM Prompt Injection and Fooling Image Classifiers.</p>
<p>In this demo, there are two example pictures. They may look very similar to us, but they are classified differently. Try it out yourself by submitting both pictures for inference and observing the results.</p>
<p>Try it out yourself by experimenting with the image on the left to see if you can cause a misclassification.</p>
<h2>What to Expect</h2>
<p>Participants will explore these concepts through interactive demos and hands-on workshops, gaining insights into applying adversarial attacks to machine learning models.</p>
<h2>NOTE</h2>
<p>This demo runs on a free-tier CPU, so its performance is slow.</p>
<h2>What can this AI Classify</h2>
<p>1. Bread</p>
<p>2. Dairy</p>
<p>3. Dessert</p>
<p>4. Egg</p>
<p>5. Fried Food</p>
<p>6. Fruit</p>
<p>7. Meat</p>
<p>8. Noodles</p>
<p>9. Rice</p>
<p>10. Seafood</p>
<p>11. Soup</p>
<p>12. Vegetable</p>
