AI Neural Network Primer is an interactive educational app that turns "neural networks" from abstract formulas into something you can play with hands-on. No AI background required, no internet needed — all models run in real time on your device. Just touch, observe, and uncover the secrets of deep learning step by step. From the first handwritten digit to the most cutting-edge large models, the courses take you from beginner to advanced: white-box visualizations let you literally "see" how data flows through every layer of the network, while hands-on training shows you why it works. 12 interactive models plus a live camera turn a textbook into an AI lab you can play with anytime. This app includes 6 fascinating courses: 1. Understanding Neural Networks Through a Single Digit Using handwritten digits as input, watch the entire forward propagation process in a white-box view — from pixels to recognition results. You can even train your first neural network yourself and witness every step as it goes from random guessing to accurate recognition. 2. What Is a Convolutional Neural Network Starting from a sample image, walk through the complete forward inference of a CNN from input to output. Follow the animation step by step to clearly see "convolution → activation → pooling → classification", and understand the core technology behind image recognition. 3. Mastering YOLO Object Detection Use the live camera or local photos to operate the YOLO model yourself and detect objects in the scene in real time. Experience real object detection technology running smoothly before your eyes. 4. Exploring Transformers Dive deep inside the Transformer model and interactively observe how text passes step by step through embedding, self-attention, and stacked Transformer blocks to finally generate coherent responses. The core of modern large language models, seen this clearly for the first time. 5. MoE: Mixture of Experts Explore the "Mixture of Experts" mechanism. Watch as the Router intelligently routes each token to the most suitable expert, and discover the secret behind how mainstream large models scale up and speed up. 6. Multimodal Large Models Experience image-text multimodal large models with SmolVLM: input an image and text at the same time, and observe how visual information merges with text to generate answers. Your gateway to multimodal technology. Why choose it: - White-box visualization: every layer and every step of computation inside the network is shown in real time — no more guessing - Hands-on learning: draw digits, pick images, turn on the camera, train models — learn while you play - Fully offline: pure on-device inference. Download models once, keep your privacy yours — zero privacy risk - Step by step: from CNNs to multimodal large models, 6 progressive courses that complete beginners can follow Whether you're a student getting started with AI, a teacher who needs visual explanations, or simply curious about neural networks — immerse yourself in a world of deep learning you can see and touch.
