Domain Adaptation for Ultrasound Beamforming

no code implementations6 Jul 2020 Jaime Tierney, Adam Luchies, Christopher Khan, Brett Byram, Matthew Berger

We address this challenge by extending cycle-consistent generative adversarial networks, where we leverage maps between synthetic simulation and real in vivo domains to ensure that the learned beamformers capture the distribution of both noisy and clean in vivo data.

Visual Supervision in Bootstrapped Information Extraction

no code implementations EMNLP 2018 Matthew Berger, Ajay Nagesh, Joshua Levine, Mihai Surdeanu, Helen Zhang

We challenge a common assumption in active learning, that a list-based interface populated by informative samples provides for efficient and effective data annotation.

A Generative Model for Volume Rendering

1 code implementation26 Oct 2017 Matthew Berger, Jixian Li, Joshua A. Levine

Additionally, the generative model transforms transfer functions into a view-invariant latent space specifically designed to synthesize volume-rendered images.

Active Perceptual Similarity Modeling with Auxiliary Information

no code implementations6 Nov 2015 Eric Heim, Matthew Berger, Lee Seversky, Milos Hauskrecht

A common way to learn such a model is from relative comparisons in the form of triplets: responses to queries of the form "Is object a more similar to b than it is to c?".
