Saliency Cards: A Framework to Characterize and Compare Saliency Methods

1 code implementation7 Jun 2022 Angie Boggust, Harini Suresh, Hendrik Strobelt, John V. Guttag, Arvind Satyanarayan

Moreover, with saliency cards, we are able to analyze the research landscape in a more structured fashion to identify opportunities for new methods and evaluation metrics for unmet user needs.

Painting Many Pasts: Synthesizing Time Lapse Videos of Paintings

1 code implementation CVPR 2020 Amy Zhao, Guha Balakrishnan, Kathleen M. Lewis, Frédo Durand, John V. Guttag, Adrian V. Dalca

We present a probabilistic model that, given a single image of a completed painting, recurrently synthesizes steps of the painting process.

A Framework for Understanding Sources of Harm throughout the Machine Learning Life Cycle

no code implementations28 Jan 2019 Harini Suresh, John V. Guttag

As machine learning (ML) increasingly affects people and society, awareness of its potential unwanted consequences has also grown.

Bolt: Accelerated Data Mining with Fast Vector Compression

1 code implementation30 Jun 2017 Davis W. Blalock, John V. Guttag

We introduce a vector quantization algorithm that can compress vectors over 12x faster than existing techniques while also accelerating approximate vector operations such as distance and dot product computations by up to 10x.

EXTRACT: Strong Examples from Weakly-Labeled Sensor Data

no code implementations29 Sep 2016 Davis W. Blalock, John V. Guttag

Thanks to the rise of wearable and connected devices, sensor-generated time series comprise a large and growing fraction of the world's data.

Uncovering Voice Misuse Using Symbolic Mismatch

no code implementations8 Aug 2016 Marzyeh Ghassemi, Zeeshan Syed, Daryush D. Mehta, Jarrad H. Van Stan, Robert E. Hillman, John V. Guttag

Voice disorders affect an estimated 14 million working-aged Americans, and many more worldwide.

Transferring Knowledge from Text to Predict Disease Onset

no code implementations6 Aug 2016 Yun Liu, Kun-Ta Chuang, Fu-Wen Liang, Huey-Jen Su, Collin M. Stultz, John V. Guttag

Specifically, we use word2vec models trained on a domain-specific corpus to estimate the relevance of each feature's text description to the prediction problem.

Patient Risk Stratification for Hospital-Associated C. diff as a Time-Series Classification Task

no code implementations NeurIPS 2012 Jenna Wiens, Eric Horvitz, John V. Guttag

A patient's risk for adverse events is affected by temporal processes including the nature and timing of diagnostic and therapeutic activities, and the overall evolution of the patient's pathophysiology over time.

Active Learning Applied to Patient-Adaptive Heartbeat Classification

no code implementations NeurIPS 2010 Jenna Wiens, John V. Guttag

While clinicians can accurately identify different types of heartbeats in electrocardiograms (ECGs) from different patients, researchers have had limited success in applying supervised machine learning to the same task.

Identifying Patients at Risk of Major Adverse Cardiovascular Events Using Symbolic Mismatch

no code implementations NeurIPS 2010 Zeeshan Syed, John V. Guttag

We hypothesize that high risk patients can be identified using symbolic mismatch, as individuals in a population with unusual long-term physiological activity.
