NeuralNet Lab-AI Model Academy

Learn how AI models work, from input data to deployment decisions. NeuralNet Lab is an AI learning companion with 420 focused micro-lessons across 70 topics and seven tracks. Each topic includes a concept map, mechanism walkthrough, worked case, failure clinic, notebook exercise and decision checkpoint. EXPLORE THE MODEL STACK • Foundations: tensors, matrix operations, derivatives, probability and numerical stability. • Data systems: contracts, missing values, scaling, leakage, labels and versioning. • Neural core: neurons, activations, dense layers, backpropagation and initialization. • Training room: gradients, batches, learning rates, optimizers and regularization. • Architectures: convolution, recurrence, attention, transformers and autoencoders. • Model evaluation: confusion matrices, precision, recall, calibration and uncertainty. • Deployment lab: transfer learning, tokenization, retrieval, quantization and monitoring. LEARN ACTIVELY Run a two-input neuron calculation and inspect its sigmoid activation. Calculate precision, recall, F1 and accuracy from confusion-matrix counts. Check understanding with topic quizzes, bookmark lessons and track completion locally. READ YOUR WAY Learning content is bundled for offline reading. Adjust the reader text size, search lesson content and return to your last lesson. Optional daily reminders help you keep a study habit; delivery time may vary with Android battery restrictions. AD-SUPPORTED LEARNING The app contains ads. Some notebook lessons offer an optional rewarded-ad unlock with a confirmation prompt. An internet connection and an available ad are needed for those unlocks. An earned unlock stays on the current device until app data is cleared or the app is uninstalled. This is an educational academy, not a general-purpose AI chatbot or a full neural-network training environment. Notebook exercises are instructions for independent practice. Interactive calculators run locally. No account is required, and progress is stored on this device.
