Journal ArticleDOI

Clinical information extraction applications: A literature review.

TL;DR: There is a considerable gap between clinical studies using EHR data and studies using clinical IE, so a more concrete understanding of the gap is gained and potential solutions to bridge this gap are provided.
Journal ArticleDOI

A comparison of word embeddings for the biomedical natural language processing

TL;DR: The qualitative evaluation shows that the word embeddings trained from EHR and MedLit can find more similar medical terms than those trained from GloVe and Google News, and the intrinsic quantitative evaluation verifies that the semantic similarity captured by the wordEmbedded is closer to human experts' judgments on all four tested datasets.
Journal ArticleDOI

AutoZOOM: Autoencoder-Based Zeroth Order Optimization Method for Attacking Black-Box Neural Networks

TL;DR: Li et al. as discussed by the authors proposed an adaptive random gradient estimation strategy to balance query counts and distortion, and an autoencoder that is either trained offline with unlabeled data or a bilinear resizing operation for attack acceleration.

Topology Attack and Defense for Graph Neural Networks: An Optimization Perspective

TL;DR: A novel gradient-based attack method is presented that facilitates the difficulty of tackling discrete graph data and yields higher robustness against both different gradient based and greedy attack methods without sacrificing classification accuracy on original graph.
Journal ArticleDOI

A clinical text classification paradigm using weak supervision and deep representation.

TL;DR: In this article, a clinical text classification paradigm using weak supervision and deep representation was proposed to reduce human efforts of labeled training data creation and feature engineering for applying machine learning to clinical text classi cation.
