1/20/2022: Automatic Binary Classification, Alexis Espinoza, Diego Henríquez and Catalina Pezo, University of Concepcion
Presentation description:
In this presentation, the speakers showed their preliminary work on Automatic ML Algorithm Selection for Binary Classification. For this, they showed how they collected and generated a number of binary classification (92 public and 4000 self-generated) instances (datasets) on which the task was to predict the correct label for the unlabeled entries, based on the labeled entries whose percentage, in each dataset, could vary. They ran 9 different classification algorithms with default parameters and trained a deep learning model as in [1], achieving a 54% accuracy on the testing dataset. Several follow-up ideas about how to generate adequate training data and characterize the instances were discussed.
