Accurate estimation of feature importance faithfulness for tree models

no code implementations4 Apr 2024 Mateusz Gajewski, Adam Karczmarz, Mateusz Rapicki, Piotr Sankowski

In this paper, we consider a perturbation-based metric of predictive faithfulness of feature rankings (or attributions) that we call PGI squared.

1 code implementation12 Feb 2024 Jakub Krajewski, Jan Ludziejewski, Kamil Adamczewski, Maciej Pióro, Michał Krutul, Szymon Antoniak, Kamil Ciebiera, Krystian Król, Tomasz Odrzygóźdź, Piotr Sankowski, Marek Cygan, Sebastian Jaszczur

Our findings not only show that MoE models consistently outperform dense Transformers but also highlight that the efficiency gap between dense and MoE models widens as we scale up the model size and training budget.

Contrastive News and Social Media Linking using BERT for Articles and Tweets across Dual Platforms

no code implementations11 Dec 2023 Jan Piotrowski, Marek Wachnicki, Mateusz Perlik, Jakub Podolak, Grzegorz Rucki, Michał Brzozowski, Paweł Olejnik, Julian Kozłowski, Tomasz Nocoń, Jakub Kozieł, Stanisław Giziński, Piotr Sankowski

Inspired by the success of the CLIP model in computer vision, which employs contrastive learning to model similarities between images and captions, this paper introduces a contrastive learning approach for training a representation space where linked articles and tweets exhibit proximity.

Improving Ads-Profitability Using Traffic-Fingerprints

no code implementations31 May 2022 Adam Gabriel Dobrakowski, Andrzej Pacuk, Piotr Sankowski, Marcin Mucha, Paweł Brach

This paper introduces the concept of traffic-fingerprints, i. e., normalized 24-dimensional vectors representing a distribution of daily traffic on a web page.

Improved Feature Importance Computations for Tree Models: Shapley vs. Banzhaf

no code implementations9 Aug 2021 Adam Karczmarz, Anish Mukherjee, Piotr Sankowski, Piotr Wygocki

Using the computational techniques developed for Shapley values we deliver an optimal $O(TL+n)$ time algorithm for computing Banzhaf values based explanations.
