ReliCD: A Reliable Cognitive Diagnosis Framework with Confidence Awareness

no code implementations29 Dec 2023 Yunfei Zhang, Chuan Qin, Dazhong Shen, Haiping Ma, Le Zhang, Xingyi Zhang, HengShu Zhu

To address this, in this paper, we propose a novel Reliable Cognitive Diagnosis(ReliCD) framework, which can quantify the confidence of the diagnosis feedback and is flexible for different cognitive diagnostic functions.

Effects of Dynamic and Stochastic Travel Times on the Operation of Mobility-on-Demand Services

no code implementations10 Aug 2023 Fynn Wolf, Roman Engelhardt, Yunfei Zhang, Florian Dandl, Klaus Bogenberger

As travel times in real street networks are dynamic and stochastic, assigned routes considered feasible by the control algorithm in one time step might become infeasible in the next.

Autonomous Vehicles as a Sensor: Simulating Data Collection Process

no code implementations9 Aug 2023 Yunfei Zhang, Mario Ilic, Klaus Bogenberger

Nevertheless, the relentless progression in autonomous driving technology has catalyzed an increasing interest in capitalizing on the extensive potential of on-board sensor data, giving rise to a novel concept known as "Autonomous Vehicles as a Sensor" (AVaaS).

Exploring Intra-Class Variation Factors With Learnable Cluster Prompts for Semi-Supervised Image Synthesis

no code implementations CVPR 2023 Yunfei Zhang, Xiaoyang Huo, Tianyi Chen, Si Wu, Hau San Wong

Semi-supervised class-conditional image synthesis is typically performed by inferring and injecting class labels into a conditional Generative Adversarial Network (GAN).

SphericGAN: Semi-Supervised Hyper-Spherical Generative Adversarial Networks for Fine-Grained Image Synthesis

no code implementations CVPR 2022 Tianyi Chen, Yunfei Zhang, Xiaoyang Huo, Si Wu, Yong Xu, Hau San Wong

To reduce the dependence of generative models on labeled data, we propose a semi-supervised hyper-spherical GAN for class-conditional fine-grained image generation, and our model is referred to as SphericGAN.

ANT: Learning Accurate Network Throughput for Better Adaptive Video Streaming

no code implementations26 Apr 2021 Jiaoyang Yin, Yiling Xu, Hao Chen, Yunfei Zhang, Steve Appleby, Zhan Ma

Adaptive Bit Rate (ABR) decision plays a crucial role for ensuring satisfactory Quality of Experience (QoE) in video streaming applications, in which past network statistics are mainly leveraged for future network bandwidth prediction.

Semi-Supervised Single-Stage Controllable GANs for Conditional Fine-Grained Image Generation

no code implementations ICCV 2021 Tianyi Chen, Yi Liu, Yunfei Zhang, Si Wu, Yong Xu, Feng Liangbing, Hau San Wong

To ensure disentanglement among the variables, we maximize mutual information between the class-independent variable and synthesized images, map real images to the latent space of a generator to perform consistency regularization of cross-class attributes, and incorporate class semantic-based regularization into a discriminator's feature space.

Practical Issues of Action-conditioned Next Image Prediction

no code implementations8 Feb 2018 Donglai Zhu, Hao Chen, Hengshuai Yao, Masoud Nosrati, Peyman Yadmellat, Yunfei Zhang

Our major finding is that action tiling encoding is the most important factor leading to the remarkable performance of the CDNA model.
