Development of Automated Neural Network Prediction for Echocardiographic Left ventricular Ejection Fraction

no code implementations18 Mar 2024 Yuting Zhang, Boyang Liu, Karina V. Bunting, David Brind, Alexander Thorley, Andreas Karwath, Wenqi Lu, Diwei Zhou, Xiaoxia Wang, Alastair R. Mobley, Otilia Tica, Georgios Gkoutos, Dipak Kotecha, Jinming Duan

Within the pipeline, an Atrous Convolutional Neural Network (ACNN) was first trained to segment the left ventricle (LV), before employing the area-length formulation based on the ellipsoid single-plane model to calculate LVEF values.

ConspEmoLLM: Conspiracy Theory Detection Using an Emotion-Based Large Language Model

1 code implementation11 Mar 2024 Zhiwei Liu, Boyang Liu, Paul Thompson, Kailai Yang, Raghav Jain, Sophia Ananiadou

Driven by a comprehensive analysis of conspiracy text that reveals its distinctive affective features, we propose ConspEmoLLM, the first open-source LLM that integrates affective information and is able to perform diverse tasks relating to conspiracy theories.

RUSH: Robust Contrastive Learning via Randomized Smoothing

no code implementations11 Jul 2022 Yijiang Pang, Boyang Liu, Jiayu Zhou

In this paper, we show a surprising fact that contrastive pre-training has an interesting yet implicit connection with robustness, and such natural robustness in the pre trained representation enables us to design a powerful robust algorithm against adversarial attacks, RUSH, that combines the standard contrastive pre-training and randomized smoothing.

Learning Deep Neural Networks under Agnostic Corrupted Supervision

no code implementations12 Feb 2021 Boyang Liu, Mengying Sun, Ding Wang, Pang-Ning Tan, Jiayu Zhou

Training deep neural models in the presence of corrupted supervision is challenging as the corrupted data points may significantly impact the generalization performance.

Polarons in a ferromagnetic spinor Bose-Einstein condensates

no code implementations21 Jan 2021 Xiao-Lu Yu, Boyang Liu

We investigate the polarons formed by immersing a spinor impurity in a ferromagnetic state of $F=1$ spinor Bose-Einstein condensate.
