Neural Network (leapai.top)

Neural Network is an interactive tutorial site that approaches machine learning from an intuition-first angle. Instead of long math derivations, it explains core concepts with charts, animations, and hands-on components so beginners can see how a network actually behaves as data flows through it. The platform is available in many languages, including Chinese, English, German, Spanish, French, Japanese and Korean.

The core experience is the visual playground: a simplified neural-network lab with 2D and 3D datasets covering both classification and regression tasks. Learners can tweak parameters, watch the outputs update in real time, and validate ideas quickly. Game-based tasks then layer in progressively harder concepts, so users pick up ideas like loss functions, regularization and activation functions through practice rather than pure memorization.

More advanced learners get a model library and a visual model editor. Classic architectures are presented as modular diagrams that show how data changes from input to output, each with documentation and, where relevant, references to papers and code. The editor lets users assemble models by dragging blocks, computing each step live and flagging errors such as incompatible parameter or input types, which makes the design-test loop far faster than traditional debugging. The site is free to use and is a third-party educational resource, not affiliated with any framework vendor.
