QUESTION
I implemented BPSO as a feature selection approach using the pyswarms library. I followed this tutorial.
Is there a way to limit the maximum number of features? If not, are there other particle swarm (or genetic/simulated annealing) python-implementations that have this functionality?
...ANSWER
Answered 2021-Mar-16 at 11:36An easy way is to introduce a penalty for using any number of features. The in the following code a objective i defined
