Minimax Classification with 0-1 Loss and Performance Guarantees

2 code implementations NeurIPS 2020 Santiago Mazuelas, Andrea Zanoni, Aritz Perez

We also present MRCs' finite-sample generalization bounds in terms of training size and smallest minimax risk, and show their competitive classification performance w. r. t.

Rank aggregation for non-stationary data streams

no code implementations19 Oct 2019 Ekhine Irurozki, Jesus Lobo, Aritz Perez, Javier Del Ser

Then, we generalize the whole family of weighted voting rules (the family to which Borda belongs) to situations in which some rankings are more \textit{reliable} than others and show that this generalization can solve the problem of rank aggregation over non-stationary data streams.

Supervised classification via minimax probabilistic transformations

no code implementations2 Feb 2019 Santiago Mazuelas, Andrea Zanoni, Aritz Perez

Conventional techniques for supervised classification constrain the classification rules considered and use surrogate losses for classification 0-1 loss.
