Adversarial Examples for Extreme Multilabel Text Classification

1 code implementation14 Dec 2021 Mohammadreza Qaraei, Rohit Babbar

Extreme Multilabel Text Classification (XMTC) is a text classification problem in which, (i) the output space is extremely large, (ii) each data point may have multiple positive labels, and (iii) the data follows a strongly imbalanced distribution.

Neural Generalization of Multiple Kernel Learning

no code implementations26 Feb 2021 Ahmad Navid Ghanizadeh, Kamaledin Ghiasi-Shirazi, Reza Monsefi, Mohammadreza Qaraei

By this interpretation, we propose a Neural Generalization of Multiple Kernel Learning (NGMKL), which extends the conventional multiple kernel learning framework to a multi-layer neural network with nonlinear activation functions.

Unbiased Loss Functions for Extreme Classification With Missing Labels

no code implementations1 Jul 2020 Erik Schultheis, Mohammadreza Qaraei, Priyanshu Gupta, Rohit Babbar

In addition to the computational burden arising from large number of training instances, features and labels, problems in XMC are faced with two statistical challenges, (i) large number of 'tail-labels' -- those which occur very infrequently, and (ii) missing labels as it is virtually impossible to manually assign every relevant label to an instance.
