Improving Radiology Report Generation Systems by Removing Hallucinated References to Non-existent Priors

1 code implementation27 Sep 2022 Vignav Ramesh, Nathan Andrew Chi, Pranav Rajpurkar

Current deep learning models trained to generate radiology reports from chest radiographs are capable of producing clinically accurate, clear, and actionable text that can advance patient care.

Contrastive learning-based pretraining improves representation and transferability of diabetic retinopathy classification models

no code implementations24 Aug 2022 Minhaj Nur Alam, Rikiya Yamashita, Vignav Ramesh, Tejas Prabhune, Jennifer I. Lim, R. V. P. Chan, Joelle Hallak, Theodore Leng, Daniel Rubin

CL based pretraining with NST significantly improves DL classification performance, helps the model generalize well (transferable from EyePACS to UIC data), and allows training with small, annotated datasets, therefore reducing ground truth annotation burden of the clinicians.

Unsupervised Tokenization Learning

no code implementations23 May 2022 Anton Kolonin, Vignav Ramesh

In the presented study, we discover that the so-called "transition freedom" metric appears superior for unsupervised tokenization purposes in comparison to statistical metrics such as mutual information and conditional probability, providing F-measure scores in range from 0. 71 to 1. 0 across explored multilingual corpora.

End-to-end Malaria Diagnosis and 3D Cell Rendering with Deep Learning

1 code implementation8 Jul 2021 Vignav Ramesh

Several deaths due to malaria are byproducts of disparities in the social determinants of health; the current gold standard for diagnosing malaria requires microscopes, reagents, and other equipment that most patients of low socioeconomic brackets do not have access to.

COVID-19 Lung Lesion Segmentation Using a Sparsely Supervised Mask R-CNN on Chest X-rays Automatically Computed from Volumetric CTs

1 code implementation17 May 2021 Vignav Ramesh, Blaine Rister, Daniel L. Rubin

Chest X-rays of coronavirus disease 2019 (COVID-19) patients are frequently obtained to determine the extent of lung disease and are a valuable source of data for creating artificial intelligence models.

Natural Language Generation Using Link Grammar for General Conversational Intelligence

1 code implementation19 Apr 2021 Vignav Ramesh, Anton Kolonin

Many current artificial general intelligence (AGI) and natural language processing (NLP) architectures do not possess general conversational intelligence--that is, they either do not deal with language or are unable to convey knowledge in a form similar to the human language without manual, labor-intensive methods such as template-based customization.

ClefNet: Recurrent Autoencoders with Dynamic Time Warping for Near-Lossless Music Compression and Minimal-Latency Transmission

1 code implementation15 Mar 2021 Vignav Ramesh, Mason Wang

The onset of coronavirus disease 2019 (COVID-19), an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has sparked unprecedented change.
