Understand the project
Practical overview
When it fits
Use it when implementing or studying machine-learning operations as Circom circuit components, especially when you need examples of layer templates and associated tests.
Who it is for
- Developers building Circom circuits that represent neural-network operations.
- Developers exploring machine-learning computations in zero-knowledge proof workflows.
Documented uses
- Represent operations such as convolution, dense layers, pooling and activation in Circom.
- Use circuit templates and test examples as a starting point for machine-learning circuit work.
- Test the repository’s circuit templates with its documented npm script.
Before you choose
Requirements & limits
The repository is public and identifies its license as GPL-3.0.
- Circom uses integer signals, so adapting floating-point weights and biases requires scaling.
- AveragePooling2D requires a separately supplied scale factor.
- Conv2D is documented as supporting valid padding only.
- The project recommends considering Poly instead of ReLU when reducing circuit constraints is important, with a performance tradeoff noted for polynomial activation.
- The README warns that it may be outdated and directs readers to the test folder for current examples.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Source-based practical guide
Run the repository’s circuit-template tests
Use the documented test command to test the circomlib-ml circuit templates.
Before you start
- A local copy of the circomlib-ml repository
- An npm environment capable of running the repository’s test script
Steps
Review the test folder for examples; the README points to it for the latest examples.
From the repository, run the command below.
npm run test
Expected outcome
The repository’s test script runs against the circuit templates.
Guide limitations
- The README warns that its documentation may be outdated.
- This describes the documented command, not an independently verified test result.
