Understanding the Evolution of the Neural Tangent Kernel at the Edge of Stability Open
The study of Neural Tangent Kernels (NTKs) in deep learning has drawn increasing attention in recent years. NTKs typically actively change during training and are related to feature learning. In parallel, recent work on Gradient Descent (G…
Fairness Risks for Group-conditionally Missing Demographics Open
Fairness-aware classification models have gained increasing attention in recent years as concerns grow on discrimination against some demographic groups. Most existing models require full knowledge of the sensitive features, which can be i…
How Does Adaptive Optimization Impact Local Neural Network Geometry? Open
Adaptive optimization methods are well known to achieve superior convergence relative to vanilla gradient methods. The traditional viewpoint in optimization, particularly in convex optimization, explains this improved performance by arguin…
Electrochemical behavior of Cu-mediated electrowinning-coupled CO2 capture Open
The emerging electrochemical CO2 captures are energy-intensive or inefficient (operated at low current density). Here, we proposed a promising electrowinning-coupled CO2 capture (ECC) system using copper (Cu) as electrochemical mediator an…
Implicit Task-Driven Probability Discrepancy Measure for Unsupervised Domain Adaptation. Open
Probability discrepancy measure is a fundamental construct for numerous machine learning models such as weakly supervised learning and generative modeling. However, most measures overlook the fact that the distributions are not the end-pro…

Techno-Economic Assessment for CO2 Capture From Air Using a Conventional Liquid-Based Absorption Process Open
In this study, the process of carbon dioxide (CO2) capture directly from ambient air in a conventional monoethanolamine (MEA) absorption process was simulated and optimized using a rate-based model in Aspen Plus. The process aimed to captu…
Reaction Enthalpy Conversion in Amine Based Post-Combustion CO 2 Capture Open
Aqueous amine based CO2 capture processes are the the leading technology for the CO2 emission reduction from the fossil fuel combusted power stations, but its commercial-scale application is largely limited by the intensive energy consumpt…
Fast flotation in a reflux flotation cell Open
The research undertaken in this study was based on a novel flotation device, the Reflux Flotation Cell (RFC). This system consists of multiple parallel inclined channels positioned below a vertical chamber. The inclined channels provide an…
