Learning to Defer to a Population: A Meta-Learning Approach

1 code implementation5 Mar 2024 Dharmesh Tailor, Aditya Patra, Rajeev Verma, Putra Manggala, Eric Nalisnick

The learning to defer (L2D) framework allows autonomous systems to be safe and robust by allocating difficult decisions to a human expert.

Meta-Learning Traffic Sign Detection

Calibrated Learning to Defer with One-vs-All Classifiers

1 code implementation8 Feb 2022 Rajeev Verma, Eric Nalisnick

We find that Mozannar & Sontag's (2020) multiclass framework is not calibrated with respect to expert correctness.

DeepSentiPeer: Harnessing Sentiment in Review Texts to Recommend Peer Review Decisions

1 code implementation ACL 2019 Tirthankar Ghosal, Rajeev Verma, Asif Ekbal, Pushpak Bhattacharyya

However, the peer review texts, which contains rich sentiment information of the reviewer, reflecting his/her overall attitude towards the research in the paper, could be a valuable entity to predict the acceptance or rejection of the manuscript under consideration.

Automatic detection of lesion load change in Multiple Sclerosis using convolutional neural networks with segmentation confidence

no code implementations5 Apr 2019 Richard McKinley, Lorenz Grunder, Rik Wepfer, Fabian Aschwanden, Tim Fischer, Christoph Friedli, Raphaela Muri, Christian Rummel, Rajeev Verma, Christian Weisstanner, Mauricio Reyes, Anke Salmen, Andrew Chan, Roland Wiest, Franca Wagner

Instead, we propose a method for identifying lesion changes of high certainty, and establish on a dataset of longitudinal multiple sclerosis cases that this method is able to separate progressive from stable timepoints with a very high level of discrimination (AUC = 0. 99), while changes in lesion volume are much less able to perform this separation (AUC = 0. 71).

Lesion Segmentation

Simultaneous lesion and neuroanatomy segmentation in Multiple Sclerosis using deep neural networks

no code implementations22 Jan 2019 Richard McKinley, Rik Wepfer, Fabian Aschwanden, Lorenz Grunder, Raphaela Muri, Christian Rummel, Rajeev Verma, Christian Weisstanner, Mauricio Reyes, Anke Salmen, Andrew Chan, Franca Wagner, Roland Wiest

We trained two state-of-the-art fully convolutional CNN architectures on the 2016 MSSEG training dataset, which was annotated by seven independent human raters: a reference implementation of a 3D Unet, and a more recently proposed 3D-to-2D architecture (DeepSCAN).
