A release has been published on hex, because I’ve found myself using parts of it in other projects. A lot of the functionality still doesn’t have proper tests, and if you’re not willing to read the code yourself, everything that isn’t simple arithmetic or function calls is probably not yet good enough for production use.
I have added new features, including support for hierarchical clustering based on dissimilarity matrices. This can be useful to perform clustering on sentence embeddings from LLMs.
I have added support for 1D kernel density estimates and 2D contouring (isolines). This package doesn’t plot them and never will, but it can be integrated with packages for plotting.
I have also added utilities to generate multidimensional arrays from Elixir lists. Thus is not very useful for practical use but it is useful for testing and exploring small examples.
In case engine wants to contribute, I suggest the following topics:
- Adding tests to the clustering logic (maybe take them from SciPy, who’s API I’m trying to emulate)
- Adding support for RustlerPrecompiled
- Find a way of integrating tests suites from other languages for the functions (even though the functions are taken from the rust stdlib or some other rust package, testing the implementation over the arrays seems like a good idea)
