rblearn (ruby-learn) provides methods for feature extracting and some algorithms.

Red Arrow Numo::NArray adds `Arrow::Tensor#to_narray` and `#to_arrow`/`#to_arrow_array` to `Numo::NArray`'s numerical subclasses such as `Numo::Int8`. `Arrow::Tensor#to_narray` returns a `Numo::NArray`'s numerical subclass such as `Numo::Int8`. `#to_arrow` returns a `Arrow::Tensor`. `#to_arrow_array` returns an `Arrow::Array` instance if the original object is an 1 dimensional array.

Red Datasets Numo::NArray adds `#to_narray` method to each dataset in Red Datasets. You can get dataset as Numo::NArray's numeric subclass object.
