MobilityGPT: Enhanced Human Mobility Modeling with a GPT model

no code implementations5 Feb 2024 Ammar Haydari, Dongjie Chen, Zhengfeng Lai, Chen-Nee Chuah

Then, we constrained the training process via a road connectivity matrix that provides the connectivity of sequences in trajectory generation, thereby keeping generated trajectories in geospatial limits.

DPGOMI: Differentially Private Data Publishing with Gaussian Optimized Model Inversion

no code implementations6 Oct 2023 Dongjie Chen, Sen-Ching S. Cheung, Chen-Nee Chuah

High-dimensional data are widely used in the era of deep learning with numerous applications.

Benchmarking Adversarial Robustness of Compressed Deep Learning Models

no code implementations16 Aug 2023 Brijesh Vora, Kartik Patwari, Syed Mahbub Hafiz, Zubair Shafiq, Chen-Nee Chuah

Our findings reveal that while the benefits of pruning enhanced generalizability, compression, and faster inference times are preserved, adversarial robustness remains comparable to the base model.

Differentially Private Generative Adversarial Networks with Model Inversion

no code implementations10 Jan 2022 Dongjie Chen, Sen-ching Samson Cheung, Chen-Nee Chuah, Sally Ozonoff

To protect sensitive data in training a Generative Adversarial Network (GAN), the standard approach is to use differentially private (DP) stochastic gradient descent method in which controlled noise is added to the gradients.

Clinical Validation of Single-Chamber Model-Based Algorithms Used to Estimate Respiratory Compliance

no code implementations19 Sep 2021 Gregory Rehm, Jimmy Nguyen, Chelsea Gilbeau, Marc T Bomactao, Chen-Nee Chuah, Jason Adams

Non-invasive estimation of respiratory physiology using computational algorithms promises to be a valuable technique for future clinicians to detect detrimental changes in patient pathophysiology.

Minimizing L1 over L2 norms on the gradient

no code implementations4 Jan 2021 Chao Wang, Min Tao, Chen-Nee Chuah, James Nagy, Yifei Lou

Consequently, we postulate that applying L1/L2 on the gradient is better than the classic total variation (the L1 norm on the gradient) to enforce the sparsity of the image gradient.

Anomaly Detection in Hierarchical Data Streams under Unknown Models

no code implementations11 Sep 2017 Sattar Vakili, Qing Zhao, Chang Liu, Chen-Nee Chuah

We consider the problem of detecting a few targets among a large number of hierarchical data streams.
