> [Rust] Implement dot-product in a compute kernel
> ------------------------------------------------
>
> Key: ARROW-11115
> URL: https://issues.apache.org/jira/browse/ARROW-11115
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust
> Reporter: Erik De Smedt
> Priority: Minor
> Labels: compute, dotproduct, linalg
>
> An efficient implementation of the
> [dot-product|https://en.wikipedia.org/wiki/Dot_product] is useful for many
> machine-learning applications.
> I would propose to treat null as zero for the implementation. This behavior
> is sensible because it corresponds to dropping any observation where
> null-data is present.
