Towards More Efficient Data Valuation in Healthcare Federated Learning using Ensembling

no code implementations12 Sep 2022 Sourav Kumar, A. Lakshminarayanan, Ken Chang, Feri Guretno, Ivan Ho Mien, Jayashree Kalpathy-Cramer, Pavitra Krishnaswamy, Praveer Singh

However, in healthcare where the number of contributing institutions are likely not of a colossal scale, computing exact SVs is still exorbitantly expensive, but not impossible.

Consistency-Based Semi-supervised Evidential Active Learning for Diagnostic Radiograph Classification

no code implementations5 Sep 2022 Shafa Balaram, Cuong M. Nguyen, Ashraf Kassim, Pavitra Krishnaswamy

Deep learning approaches achieve state-of-the-art performance for classifying radiology images, but rely on large labelled datasets that require resource-intensive annotation by specialists.

Semi-supervised classification of radiology images with NoTeacher: A Teacher that is not Mean

no code implementations10 Aug 2021 Balagopal Unnikrishnan, Cuong Nguyen, Shafa Balaram, Chao Li, Chuan Sheng Foo, Pavitra Krishnaswamy

Specifically, we describe adaptations for scenarios with 2D and 3D inputs, uni and multi-label classification, and class distribution mismatch between labeled and unlabeled portions of the training data.

Uncertainty Modeling for Machine Comprehension Systems using Efficient Bayesian Neural Networks

no code implementations COLING 2020 Zhengyuan Liu, Pavitra Krishnaswamy, Ai Ti Aw, Nancy Chen

While neural approaches have achieved significant improvement in machine comprehension tasks, models often work as a black-box, resulting in lower interpretability, which requires special attention in domains such as healthcare or education.

Online Deep Learning: Growing RBM on the fly

no code implementations6 Mar 2018 Savitha Ramasamy, Kanagasabai Rajaraman, Pavitra Krishnaswamy, Vijay Chandrasekhar

The online generative training begins with zero neurons in the hidden layer, adds and updates the neurons to adapt to statistics of streaming data in a single pass unsupervised manner, resulting in a feature representation best suited to the data.
