Tablesaw makes it easy to use Java for data science, but we can use your help. Here are some ways you can contribute today:
Please use the project Issues section on Github to ask questions, tagging the issue as a “Question”.
All our docs are in the docs folder of the tablesaw repo, and they are all written in Markdown. To provide enhancements, follow the directions on how to implement featues and bugs below as the workflow is basically the same.
We could always use better test coverage. If you see a gap you’d like to fill, follow the basic Github process outlined below.
If you want to help out with one of our bugs or implement a new feature, here are some suggestions for success. The basic process looks like this:
Among the open bugs and feature requests, we’ve tagged some as “Help Wanted”. This indicates that a fix should be relatively straightforward to address. We would, of course, LOVE help on some of the more challenging issues. Help Wanted simply means that this is a good place for a developer with limited knowlege of the library and/or limited experience with Java to jump in.
We’d also love to add support for more machine learning algorithms by adding new interfaces to Smile. Basically, you’re creating methods that transform tables to the format the Smile needs, and wraps the Smile API so that the necessary options can be set through Tablesaw. Some knowledge of Smile or machine learning would, of course, be helpful. Look at existing interfaces between Tablesaw and Smile before you start. The best solutions would include an example that shows how to use the algorithm end-to-end, including preliminary data exploration to see if the data is a good fit for the model, and showing how to use diagnostics to evaluate the model. The full example is not a requirement for the pull requests, however.
We are actively seeking new maintainers for the project. The best way to get involved is to familiarize yourself with the project through use, and make a few minor changes/fixes. After that, introduce yourself by emailing firstname.lastname@example.org and we’ll get in touch.
