Improved iterative methods for solving risk parity portfolio

3 code implementations28 Feb 2022 Jaehyuk Choi, Rong Chen

Risk parity, also known as equal risk contribution, has recently gained increasing attention as a portfolio allocation method.

Independent Reinforcement Learning for Weakly Cooperative Multiagent Traffic Control Problem

1 code implementation22 Apr 2021 Chengwei Zhang, Shan Jin, Wanli Xue, Xiaofei Xie, ShengYong Chen, Rong Chen

To this, we model the traffic control problem as a partially observable weak cooperative traffic model (PO-WCTM) to optimize the overall traffic situation of a group of intersections.

Distributed Learning with Low Communication Cost via Gradient Boosting Untrained Neural Network

no code implementations10 Nov 2020 Xiatian Zhang, Xunshi He, Nan Wang, Rong Chen

For high-dimensional data, there are huge communication costs for distributed GBDT because the communication volume of GBDT is related to the number of features.

KoPA: Automated Kronecker Product Approximation

no code implementations5 Dec 2019 Chencheng Cai, Rong Chen, Han Xiao

Specifically, we propose to approximate a given matrix by the sum of a few Kronecker products of matrices, which we refer to as the Kronecker product approximation (KoPA).

Bi-GANs-ST for Perceptual Image Super-resolution

no code implementations1 Nov 2018 Xiaotong Luo, Rong Chen, Yuan Xie, Yanyun Qu, Cuihua Li

In this paper, motivated by [1], we aim to generate a high-quality SR result which balances between the two indices, i. e., the perception index and root-mean-square error (RMSE).

SCC-rFMQ Learning in Cooperative Markov Games with Continuous Actions

no code implementations18 Sep 2018 Chengwei Zhang, Xiaohong Li, Jianye Hao, Siqi Chen, Karl Tuyls, Zhiyong Feng, Wanli Xue, Rong Chen

Although many reinforcement learning methods have been proposed for learning the optimal solutions in single-agent continuous-action domains, multiagent coordination domains with continuous actions have received relatively few investigations.
