I mostly took inspiration from the Rust integration because Swift and Rust are similar

[Rust Bindings] Poor performance VS ndarray (BLAS) and optimized iteration impls

11

Recently we've been implementing some spacial distance functions and benchmarking them against some existing libraries, when testing with high dimensional data (1024 dims) we observe `simsimd` taking on average `619ns`...

Sparse Distances

4

All existing metrics imply dense vector representations. Dealing with very high-dimensional vectors, sparse representations may provide huge space-efficiency gains. The only operation that needs to be implemented for Jaccard, Hamming,...

Add covariance estimators

2

Covariance isn't a distance function, as it can be negative. It however, is often used for similarity search over time-series and should be implemented in SimSIMD.

golang: separate c functions and cache simsimd_metric_punned

6

The changes move the inline C functions from simsimd.go to a new file, simsimd.c. This separation enhances code organization and readability. It also allows for better management of the C...

GoLang bindings

2

Initial [implementation](https://github.com/ashvardanian/SimSIMD/commit/7461e8acd2c71afefd6054b7034a4d21709db13f) is very slow, due to the costs of cGo calls.

AMX support for tiled matrix multiplications

2

Both Intel and Apple now have specialized AMX tiled matrix multiplication extensions. Both are tricky to use, but may result in substantial performance improvements. Potentially even for single vector dot-products...

Memory usage problems

Hello @ashvardanian ! Been meaning to use `simsimd.cdist` hamming distance with `np.uint8` arrays, but I'm having execution time issues (long execution times) as well as huge memory consumption. I'm trying...

[python] Create an interface file

It would be nice to have a `.pyi` integrated to the python package that would expose the types for IDEs auto-completion and type checkers.
