Equal Incremental Cost-Based Optimization Method to Enhance Efficiency for IPOP-Type Converters

no code implementations12 Nov 2023 Hanfeng Cai, Haiyang Liu, Heyang Sun, Qiao Wang

This paper addresses the issue of enhancing the efficiency of a multiple module system connected in parallel during operation and proposes an algorithm based on equal incremental cost for dynamic load allocation.

Multi-Scale Spatial-Temporal Recurrent Networks for Traffic Flow Prediction

no code implementations12 Oct 2023 Haiyang Liu, Chunjiang Zhu, Detian Zhang, Qing Li

Traffic flow prediction is one of the most fundamental tasks of intelligent transportation systems.

Exploring the Mutual Influence between Self-Supervised Single-Frame and Multi-Frame Depth Estimation

1 code implementation25 Apr 2023 Jie Xiang, Yun Wang, Lifeng An, Haiyang Liu, Jian Liu

Although both self-supervised single-frame and multi-frame depth estimation methods only require unlabeled monocular videos for training, the information they leverage varies because single-frame methods mainly rely on appearance-based features while multi-frame methods focus on geometric cues.

no code implementations25 Feb 2023 Haiyang Liu, Chunjiang Zhu, Detian Zhang, Qing Li

The key challenge is to effectively model complex spatial-temporal dependencies and correlations in modern traffic data.

Visual Attention-based Self-supervised Absolute Depth Estimation using Geometric Priors in Autonomous Driving

2 code implementations18 May 2022 Jie Xiang, Yun Wang, Lifeng An, Haiyang Liu, Zijun Wang, Jian Liu

Although existing monocular depth estimation methods have made great progress, predicting an accurate absolute depth map from a single image is still challenging due to the limited modeling capacity of networks and the scale ambiguity issue.

Self-Supervision and Spatial-Sequential Attention Based Loss for Multi-Person Pose Estimation

no code implementations20 Oct 2021 Haiyang Liu, Dingli Luo, Songlin Du, Takeshi Ikenaga

To solve these problems, this paper proposes (i) a new loss organization method which uses self-supervised heatmaps to reduce prediction contradictions and spatial-sequential attention to enhance networks' features extraction; (ii) a new combination of predictions composed by heatmaps, Part Affinity Fields (PAFs) and our block-inside offsets to fix pixel-level joints positions and further demonstrates the effectiveness of proposed loss function.
