Optimal Management of DC Pension Plan with Inflation Risk and Tail VaR Constraint

no code implementations5 Sep 2023 Hui Mi, Zuo Quan Xu, Dongfang Yang

This paper investigates an optimal investment problem under the tail Value at Risk (tail VaR, also known as expected shortfall, conditional VaR, average VaR) and portfolio insurance constraints confronted by a defined-contribution pension member.

3D Harmonic Loss: Towards Task-consistent and Time-friendly 3D Object Detection on Edge for V2X Orchestration

1 code implementation7 Nov 2022 Haolin Zhang, M S Mekala, Zulkar Nain, Dongfang Yang, Ju H. Park, Ho-Youl Jung

Edge computing-based 3D perception has received attention in intelligent transportation systems (ITS) because real-time monitoring of traffic candidates potentially strengthens Vehicle-to-Everything (V2X) orchestration.

Predicting Pedestrian Crossing Intention with Feature Fusion and Spatio-Temporal Attention

3 code implementations12 Apr 2021 Dongfang Yang, Haolin Zhang, Ekim Yurtsever, Keith Redmill, Ümit Özgüner

This work addresses the above limitations by introducing a novel neural network architecture to fuse inherently different spatio-temporal features for pedestrian crossing intention prediction.

On the Generalizability of Motion Models for Road Users in Heterogeneous Shared Traffic Spaces

no code implementations18 Jan 2021 Fatema T. Johora, Dongfang Yang, Jörg P. Müller, Ümit Özgüner

The results indicate that our model can realistically simulate a wide range of motion behaviors and interaction scenarios, and that adding different motion patterns of pedestrians into our model improves its performance.

Faraway-Frustum: Dealing with Lidar Sparsity for 3D Object Detection using Fusion

1 code implementation3 Nov 2020 Haolin Zhang, Dongfang Yang, Ekim Yurtsever, Keith A. Redmill, Ümit Özgüner

The main strategy is to depend solely on the 2D vision for recognizing object class, as object shape does not change drastically with an increase in depth, and use pointcloud data for object localization in the 3D space for faraway objects.

Photorealism in Driving Simulations: Blending Generative Adversarial Image Synthesis with Rendering

no code implementations31 Jul 2020 Ekim Yurtsever, Dongfang Yang, Ibrahim Mert Koc, Keith A. Redmill

Given a 3D scene, we partially render only important objects of interest, such as vehicles, and use generative adversarial processes to synthesize the background and the rest of the image.

A Vision-based Social Distancing and Critical Density Detection System for COVID-19

1 code implementation7 Jul 2020 Dongfang Yang, Ekim Yurtsever, Vishnu Renganathan, Keith A. Redmill, Ümit Özgüner

If a violation is detected, a non-intrusive audio-visual warning signal is emitted without targeting the individual who breached the social distancing measure.

Road-network-based Rapid Geolocalization

no code implementations25 Jun 2019 Yongfei Li, Dongfang Yang, Shicheng Wang, Hao He

We test all the candidate matching tuples under a hypothesise-and-test framework to search for the best match.

Top-view Trajectories: A Pedestrian Dataset of Vehicle-Crowd Interaction from Controlled Experiments and Crowded Campus

2 code implementations1 Feb 2019 Dongfang Yang, Linhui Li, Keith Redmill, Ümit Özgüner

The final trajectories of pedestrians and vehicles were refined by Kalman filters with linear point-mass model and nonlinear bicycle model, respectively, in which xy-velocity of pedestrians and longitudinal speed and orientation of vehicles were estimated.
