Unsupervised domain adaptation with non-stochastic missing data

1 code implementation16 Sep 2021 Matthieu Kirchmeyer, Patrick Gallinari, Alain Rakotomamonjy, Amin Mantrach

Moreover, we compare the target error of our Adaptation-imputation framework and the "ideal" target error of a UDA classifier without missing target components.

Unsupervised domain adaptation with imputation

no code implementations25 Sep 2019 Matthieu Kirchmeyer, Patrick Gallinari, Alain Rakotomamonjy, Amin Mantrach

Motivated by practical applications, we consider unsupervised domain adaptation for classification problems, in the presence of missing data in the target domain.

Deep Character-Level Click-Through Rate Prediction for Sponsored Search

1 code implementation7 Jul 2017 Bora Edizel, Amin Mantrach, Xiao Bai

Finally, by combining the predictions of the deep models introduced in this study with the prediction of the model in production of the same commercial search engine, we significantly improve the accuracy and the calibration of the click-through rate prediction of the production system.

Dynamic Matrix Factorization with Priors on Unknown Values

1 code implementation23 Jul 2015 Robin Devooght, Nicolas Kourtellis, Amin Mantrach

In each case, we outrank state-of-the-art matrix factorization methods that do not use a prior on unknown ratings.

A bag-of-paths framework for network data analysis

no code implementations27 Feb 2013 Kevin Françoisse, Ilkka Kivimäki, Amin Mantrach, Fabrice Rossi, Marco Saerens

This probability captures a notion of relatedness between nodes of the graph: two nodes are considered as highly related when they are connected by many, preferably low-cost, paths.
