[HTML][HTML] Snuba: Automating weak supervision to label training data

P Varma, C Ré - … of the VLDB Endowment. International Conference …, 2018 - ncbi.nlm.nih.gov
As deep learning models are applied to increasingly diverse problems, a key bottleneck is
gathering enough high-quality training labels tailored to each task. Users therefore turn to …

Parameterizing neural power spectra into periodic and aperiodic components

T Donoghue, M Haller, EJ Peterson, P Varma… - Nature …, 2020 - nature.com
Electrophysiological signals exhibit both periodic and aperiodic properties. Periodic oscillations
have been linked to numerous physiological, cognitive, behavioral and disease states. …

[HTML][HTML] Training classifiers with natural language explanations

B Hancock, M Bringmann, P Varma… - Proceedings of the …, 2018 - ncbi.nlm.nih.gov
Training accurate classifiers requires many labels, but each label provides only limited
information (one bit for binary classification). In this work, we propose BabbleLabble, a framework …

Scene graph prediction with limited labels

VS Chen, P Varma, R Krishna… - Proceedings of the …, 2019 - openaccess.thecvf.com
Visual knowledge bases such as Visual Genome power numerous applications in computer
vision, including visual question answering and captioning, but suffer from sparse, …

Inferring generative model structure with static analysis

P Varma, BD He, P Bajaj… - Advances in neural …, 2017 - proceedings.neurips.cc
Obtaining enough labeled data to robustly train complex discriminative models is a major
bottleneck in the machine learning pipeline. A popular solution is combining multiple sources …

Parameterizing neural power spectra

M Haller, T Donoghue, E Peterson, P Varma… - BioRxiv, 2018 - biorxiv.org
Electrophysiological signals across species and recording scales exhibit both periodic and
aperiodic features. Periodic oscillations have been widely studied and linked to numerous …

[HTML][HTML] Weakly supervised classification of aortic valve malformations using unlabeled cardiac MRI sequences

JA Fries, P Varma, VS Chen, K Xiao, H Tejeda… - Nature …, 2019 - nature.com
Biomedical repositories such as the UK Biobank provide increasing access to prospectively
collected cardiac imaging, however these data are unlabeled, which creates barriers to their …

Learning dependency structures for weak supervision models

P Varma, F Sala, A He, A Ratner… - … Conference on Machine …, 2019 - proceedings.mlr.press
Labeling training data is a key bottleneck in the modern machine learning pipeline. Recent
weak supervision approaches combine labels from multiple noisy sources by estimating their …

Multi-resolution weak supervision for sequential data

P Varma, F Sala, S Sagawa, J Fries… - Advances in …, 2019 - proceedings.neurips.cc
Since manually labeling training data is slow and expensive, recent industrial and scientific
research efforts have turned to weaker or noisier forms of supervision sources. However, …

Nonlinear optimization algorithm for partially coherent phase retrieval and source recovery

J Zhong, L Tian, P Varma… - IEEE Transactions on …, 2016 - ieeexplore.ieee.org
We propose a new algorithm for recovering both complex field (phase and amplitude) and
source distribution (illumination spatial coherence) from a stack of intensity images captured …
