Detector-in-Detector: Multi-Level Analysis for Human-Parts

2 code implementations19 Feb 2019 Xiaojie Li, Lu Yang, Qing Song, Fuqiang Zhou

In particular, we adopt a region-based object detection structure with two carefully designed detectors to separately pay attention to the human body and body parts in a coarse-to-fine manner, which we call Detector-in-Detector network (DID-Net).

Domain Embedded Multi-model Generative Adversarial Networks for Image-based Face Inpainting

no code implementations5 Feb 2020 Xian Zhang, Xin Wang, Bin Kong, Youbing Yin, Qi Song, Siwei Lyu, Jiancheng Lv, Canghong Shi, Xiaojie Li

We firstly represent only face regions using the latent variable as the domain knowledge and combine it with the non-face parts textures to generate high-quality face images with plausible contents.

Agree to Disagree: Adaptive Ensemble Knowledge Distillation in Gradient Space

1 code implementation NeurIPS 2020 Shangchen Du, Shan You, Xiaojie Li, Jianlong Wu, Fei Wang, Chen Qian, ChangShui Zhang

In this paper, we examine the diversity of teacher models in the gradient space and regard the ensemble knowledge distillation as a multi-objective optimization problem so that we can determine a better optimization direction for the training of student network.

Face Deblurring Based on Separable Normalization and Adaptive Denormalization

no code implementations18 Dec 2021 Xian Zhang, Hao Zhang, Jiancheng Lv, Xiaojie Li

Face deblurring aims to restore a clear face image from a blurred input image with more explicit structure and facial details.

HEAD: HEtero-Assists Distillation for Heterogeneous Object Detectors

1 code implementation12 Jul 2022 Luting Wang, Xiaojie Li, Yue Liao, Zeren Jiang, Jianlong Wu, Fei Wang, Chen Qian, Si Liu

We observe that the core difficulty for heterogeneous KD (hetero-KD) is the significant semantic gap between the backbone features of heterogeneous detectors due to the different optimization manners.

Cross-Modality Domain Adaptation for Freespace Detection: A Simple yet Effective Baseline

no code implementations6 Oct 2022 Yuanbin Wang, Leyan Zhu, Shaofei Huang, Tianrui Hui, Xiaojie Li, Fei Wang, Si Liu

To better bridge the domain gap between source domain (synthetic data) and target domain (real-world data), we also propose a Selective Feature Alignment (SFA) module which only aligns the features of consistent foreground area between the two domains, thus realizing inter-domain intra-modality adaptation.

GenView: Enhancing View Quality with Pretrained Generative Model for Self-Supervised Learning

1 code implementation18 Mar 2024 Xiaojie Li, Yibo Yang, Xiangtai Li, Jianlong Wu, Yue Yu, Bernard Ghanem, Min Zhang

To tackle these challenges, we present GenView, a controllable framework that augments the diversity of positive views leveraging the power of pretrained generative models while preserving semantics.

RadioGAT: A Joint Model-based and Data-driven Framework for Multi-band Radiomap Reconstruction via Graph Attention Networks

no code implementations25 Mar 2024 Xiaojie Li, Songyang Zhang, Hang Li, Xiaoyang Li, Lexi Xu, Haigao Xu, Hui Mei, Guangxu Zhu, Nan Qi, Ming Xiao

Multi-band radiomap reconstruction (MB-RMR) is a key component in wireless communications for tasks such as spectrum management and network planning.

Data-driven parallel Koopman subsystem modeling and distributed moving horizon state estimation for large-scale nonlinear processes

no code implementations10 Apr 2024 Xiaojie Li, Song Bo, Xuewen Zhang, Yan Qin, Xunyuan Yin

The local estimators are integrated via information exchange to form a distributed estimation scheme, which provides estimates of the unmeasured/unmeasurable state variables of the original nonlinear process in a linear manner.

Partition-based distributed extended Kalman filter for large-scale nonlinear processes with application to chemical and wastewater treatment processes

no code implementations10 Apr 2024 Xiaojie Li, Adrian Wing-Keung Law, Xunyuan Yin

In this paper, we address a partition-based distributed state estimation problem for large-scale general nonlinear processes by proposing a Kalman-based approach.

Iterative distributed moving horizon estimation of linear systems with penalties on both system disturbances and noise

no code implementations10 Apr 2024 Xiaojie Li, Song Bo, Yan Qin, Xunyuan Yin

In this paper, partition-based distributed state estimation of general linear systems is considered.
