Hi!
distances - order(distancevector(scaled_DB, scaled_DB['query',],
d=euclid))
Just compute the distances WITHOUT ordering, here. And then
1) create a small top_five frame
top = scaled_DB[rank(distances)=5, ]
rank() is better for this than order() in case there are ties.
2)

Hello,
this is probably trivial but I failed to find this
particular snippet of code.
What I got:
my_dataframe (contains say a 40k rows and 4 columns)
distances (vector with euclidean distances between a
query vector and each of the rows of my_dataframe)
What I do:
after scaling data
