Customizing pairwise costs
Hello, thank you for the great library!
I want to implement a custom pairwise cost functor, which takes labels and maps the labels to something else to calculate the costs. For example, if the labels are indices of some set of n-dimensional points, I want to define the pairwise costs as the distance between the points which the labels point to. Is this possible?
I have tried implementing a class derived from mapmap::PairwiseCosts
, and override the get_pairwise_costs
method. When I try to output the labels vector in get_pairwise_costs
, sometimes it outputs undefined values (i.e. not labels). Could you please give some instructions on how to define custom pairwise costs? I would be very appreciated.
Hi @blurgyy ,
sorry for the late answer! Can you, by any chance, post your code here? A good starting point would be pairwise_table.impl.h.
Did you use a SIMD width larger than 1? If so, my first guess is always an alignment issue...
Feel free to also e-mail me directly (see my personal webpage).
