– You mention an improved recall after hyperparameter optimization, but don’t discuss strategies on how to target improved recall. How could we expect that changing the hyperparameters like we did, we would end up with improved recall? Because we used accuracy / Matthews correlation as metrics to decide on the hyperparameters.
