Detection of Opioid Users from Reddit Posts via an Attention-based Bidirectional Recurrent Neural Network

1 code implementation9 Feb 2024 Yuchen Wang, Zhengyu Fang, Wei Du, Shuai Xu, Rong Xu, Jing Li

The opioid epidemic, referring to the growing hospitalizations and deaths because of overdose of opioid usage and addiction, has become a severe health problem in the United States.

Learning the Market: Sentiment-Based Ensemble Trading Agents

no code implementations2 Feb 2024 Andrew Ye, James Xu, Yi Wang, Yifan Yu, Daniel Yan, Ryan Chen, Bosheng Dong, Vipin Chaudhary, Shuai Xu

We propose the integration of sentiment analysis and deep-reinforcement learning ensemble algorithms for stock trading, and design a strategy capable of dynamically altering its employed agent given concurrent market sentiment.

Winner-Take-All Column Row Sampling for Memory Efficient Adaptation of Language Model

1 code implementation NeurIPS 2023 Zirui Liu, Guanchu Wang, Shaochen Zhong, Zhaozhuo Xu, Daochen Zha, Ruixiang Tang, Zhimeng Jiang, Kaixiong Zhou, Vipin Chaudhary, Shuai Xu, Xia Hu

While the model parameters do contribute to memory usage, the primary memory bottleneck during training arises from storing feature maps, also known as activations, as they are crucial for gradient calculation.

Improving CNN-base Stock Trading By Considering Data Heterogeneity and Burst

no code implementations14 Mar 2023 Keer Yang, Guanqun Zhang, Chuan Bi, Qiang Guan, Hailu Xu, Shuai Xu

In recent years, there have been quite a few attempts to apply intelligent techniques to financial trading, i. e., constructing automatic and intelligent trading framework based on historical stock price.

Revisit Kernel Pruning with Lottery Regulated Grouped Convolutions

1 code implementation ICLR 2022 Shaochen Zhong, Guanqun Zhang, Ningjia Huang, Shuai Xu

In this paper, we revisit the idea of kernel pruning (to only prune one or several $k \times k$ kernels out of a 3D-filter), a heavily overlooked approach under the context of structured pruning due to it will naturally introduce sparsity to filters within the same convolutional layer—thus, making the remaining network no longer dense.

Quantum-Inspired Classical Algorithm for Principal Component Regression

no code implementations16 Oct 2020 Daniel Chen, Yekun Xu, Betis Baheri, Chuan Bi, Ying Mao, Qiang Quan, Shuai Xu

In this work, we developed an algorithm for principal component regression that runs in time polylogarithmic to the number of data points, an exponential speed up over the state-of-the-art algorithm, under the mild assumption that the input is given in some data structure that supports a norm-based sampling procedure.

A modified Physarum-inspired model for the user equilibrium traffic assignment problem

no code implementations19 Dec 2016 Shuai Xu, Wen Jiang, Yehang Shou

The user equilibrium traffic assignment principle is very important in the traffic assignment problem.
