Efficient estimation of word representations in vector space

T Mikolov, K Chen, G Corrado, J Dean - arXiv preprint arXiv:1301.3781, 2013 - arxiv.org
We propose two novel model architectures for computing continuous vector representations
of words from very large data sets. The quality of these representations is measured in a …

MMDetection: Open mmlab detection toolbox and benchmark

K Chen, J Wang, J Pang, Y Cao, Y Xiong, X Li… - arXiv preprint arXiv …, 2019 - arxiv.org
We present MMDetection, an object detection toolbox that contains a rich set of object detection
and instance segmentation methods as well as related components and modules. The …

Large scale distributed deep networks

J Dean, G Corrado, R Monga, K Chen… - Advances in neural …, 2012 - proceedings.neurips.cc
Recent work in unsupervised feature learning and deep learning has shown that being able
to train large models can dramatically improve performance. In this paper, we consider the …

Regulation of ROS signal transduction by NADPH oxidase 4 localization

K Chen, MT Kirber, H Xiao, Y Yang… - The Journal of cell …, 2008 - rupress.org
Reactive oxygen species (ROS) function as intracellular signaling molecules in a diverse
range of biological processes. However, it is unclear how freely diffusible ROS dictate specific …

Libra r-cnn: Towards balanced learning for object detection

J Pang, K Chen, J Shi, H Feng… - Proceedings of the …, 2019 - openaccess.thecvf.com
Compared with model architectures, the training process, which is also crucial to the success
of detectors, has received relatively less attention in object detection. In this work, we …

Distributed representations of words and phrases and their compositionality

T Mikolov, I Sutskever, K Chen… - Advances in neural …, 2013 - proceedings.neurips.cc
The recently introduced continuous Skip-gram model is an efficient method for learning high-quality
distributed vector representations that capture a large number of precise syntactic …

Neuropilin-1 is a host factor for SARS-CoV-2 infection

JL Daly, B Simonetti, K Klein, KE Chen, MK Williamson… - Science, 2020 - science.org
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of
coronavirus disease 2019 (COVID-19), uses the viral spike (S) protein for host cell attachment …

[PDF][PDF] N6-methyladenosine modulates messenger RNA translation efficiency

…, IA Roundtree, Z Lu, D Han, H Ma, X Weng, K Chen… - Cell, 2015 - cell.com
N 6 -methyladenosine (m 6 A) is the most abundant internal modification in mammalian
mRNA. This modification is reversible and non-stoichiometric and adds another layer to the …

Decoy state quantum key distribution

HK Lo, X Ma, K Chen - Physical review letters, 2005 - APS
There has been much interest in quantum key distribution. Experimentally, quantum key
distribution over 150 km of commercial Telecom fibers has been successfully performed. The …

miRTarBase 2020: updates to the experimentally validated microRNA–target interaction database

…, S Shrestha, HC Hong, Y Tang, YG Chen… - Nucleic acids …, 2020 - academic.oup.com
MicroRNAs (miRNAs) are small non-coding RNAs (typically consisting of 18–25 nucleotides)
that negatively control expression of target genes at the post-transcriptional level. Owing to …
