AI on Browser
Machine learning and data analysis package implemented in JavaScript and its online demo.
Features
- Most of the models are completed in a single file and implemented in a simple way.
- The machine learning part of the code does not use any external libraries, except for the loading part of the ONNX file.
- All processing in the demo is done in client-side JavaScript.
Links
Caution
- The code is not practical in terms of speed, memory usage, etc.
- There is no single compact file, and each model file exists only separately. However, it is possible to use them from the default import as shown in Example.
