Towards More Robust NLP System Evaluation: Handling Missing Scores in Benchmarks

no code implementations17 May 2023 Anas Himmi, Ekhine Irurozki, Nathan Noiry, Stephan Clemencon, Pierre Colombo

This paper formalize an existing problem in NLP research: benchmarking when some systems scores are missing on the task, and proposes a novel approach to address it.

Robust Consensus in Ranking Data Analysis: Definitions, Properties and Computational Issues

1 code implementation22 Mar 2023 Morgane Goibert, Clément Calauzènes, Ekhine Irurozki, Stéphan Clémençon

As the issue of robustness in AI systems becomes vital, statistical learning techniques that are reliable even in presence of partly contaminated data have to be developed.

What are the best systems? New perspectives on NLP Benchmarking

1 code implementation8 Feb 2022 Pierre Colombo, Nathan Noiry, Ekhine Irurozki, Stephan Clemencon

In Machine Learning, a benchmark refers to an ensemble of datasets associated with one or multiple metrics together with a way to aggregate different systems performances.

Statistical Depth Functions for Ranking Distributions: Definitions, Statistical Learning and Applications

no code implementations20 Jan 2022 Morgane Goibert, Stéphan Clémençon, Ekhine Irurozki, Pavlo Mozharovskyi

The concept of median/consensus has been widely investigated in order to provide a statistical summary of ranking data, i. e. realizations of a random permutation $\Sigma$ of a finite set, $\{1,\; \ldots,\; n\}$ with $n\geq 1$ say.

Kernels of Mallows Models under the Hamming Distance for solving the Quadratic Assignment Problem

1 code implementation19 Oct 2019 Etor Arza, Aritz Perez, Ekhine Irurozki, Josu Ceberio

The Quadratic Assignment Problem (QAP) is a well-known permutation-based combinatorial optimization problem with real applications in industrial and logistics environments.

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.
