Machine Learning in Elixir: Mutate not working, missing pin ^ (Iris example, Chapter 1)
@seanmor5
For Explorer.Query to access variables defined outside of the query ^ must be used.
Updated in the example below:
cols = ~w(sepal_width sepal_length petal_length petal_width)
normalised_iris =
DF.mutate(
iris,
for col <- across(^cols) do
{col.name, (col - mean(col)) / variance(col)}
end
)
First Post!
