On Robustness and Generalization of ML-Based Congestion Predictors to Valid and Imperceptible Perturbations

no code implementations29 Feb 2024 Chester Holtz, Yucheng Wang, Chung-Kuan Cheng, Bill Lin

Namely, we show that when a small number of cells (e. g. 1%-5% of cells) have their positions shifted such that a measure of global congestion is guaranteed to remain unaffected (e. g. 1% of the design adversarially shifted by 0. 001% of the layout space results in a predicted decrease in congestion of up to 90%, while no change in congestion is implied by the perturbation).

Semi-Supervised Laplacian Learning on Stiefel Manifolds

no code implementations31 Jul 2023 Chester Holtz, PengWen Chen, Alexander Cloninger, Chung-Kuan Cheng, Gal Mishne

Motivated by the need to address the degeneracy of canonical Laplace learning algorithms in low label rates, we propose to reformulate graph-based semi-supervised learning as a nonconvex generalization of a \emph{Trust-Region Subproblem} (TRS).

Using EEG Signals to Assess Workload during Memory Retrieval in a Real-world Scenario

no code implementations14 May 2023 Kuan-Jung Chiang, Steven Dong, Chung-Kuan Cheng, Tzyy-Ping Jung

Objective: The Electroencephalogram (EEG) is gaining popularity as a physiological measure for neuroergonomics in human factor studies because it is objective, less prone to bias, and capable of assessing the dynamics of cognitive states.
