            QUESTION

            Is there any way to choose how many features are selected in Binary Particle Swarm Optimization?
            Asked 2021-Mar-16 at 11:36

            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?

            An easy way is to introduce a penalty for using any number of features. The in the following code a objective i defined
