Nailfold capillaroscopy and deep learning in diabetes 甲襞毛细血管镜检测与深度学习在糖尿病中的应用

open access: yesJournal of Diabetes, Volume 15, Issue 2, Page 145-151, February 2023., 2023
Highlights Nailfold capillary images were obtained by performing nailfold video capillaroscopy in 120 adult patients with and without diabetes. Over 5000 photographs were analyzed using machine‐learning approaches, and these models were clearly able to distinguish people based on diabetes status.

Continuous on‐board behaviour classification using accelerometry: A case study with a new GPS‐3G‐Bluetooth system in Pacific black ducks

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 7, Page 1429-1435, July 2022., 2022
Abstract Over the past two decades, accelerometer (ACC) data have been increasingly used to study animal behaviours and energetics. However, the large amount of raw ACC data can be a burden to device storage and power consumption and in many cases may also require device retrieval for data collection.

Do Machines Replicate Humans? Toward a Unified Understanding of Radicalizing Content on the Open Social Web

open access: yesPolicy &Internet, Volume 12, Issue 1, Page 109-138, March 2020., 2020
The advent of the Internet inadvertently augmented the functioning and success of violent extremist organizations. Terrorist organizations like the Islamic State in Iraq and Syria (ISIS) use the Internet to project their message to a global audience. The majority of research and practice on web‐based terrorist propaganda uses human coders to classify ...
