Importance-aware Topic Modeling for Discovering Public Transit Risk from Noisy Social Media
Fatima Ashraf, Muhammad Ayub Sabir, Jiaxin Deng +2
Urban transit agencies increasingly turn to social media to monitor emerging service risks such as crowding, delays, and safety incidents, yet the signals of concern are sparse, sh…
Rectify and Align GPS Points to Parking Spots via Rank-1 Constraint
Jiaxing Deng, Junbiao Pang, Zhicheng Wang +1
Parking spots are essential components, providing vital mobile resources for residents in a city. Accurate Global Positioning System (GPS) points of parking spots are the core data…
Adaptively Sampling-Reusing-Mixing Decomposed Gradients to Speed Up Sharpness Aware Minimization
Jiaxin Deng, Junbiao Pang
Sharpness-Aware Minimization (SAM) improves model generalization but doubles the computational cost of Stochastic Gradient Descent (SGD) by requiring twice the gradient calculation…
Efficiently Seeking Flat Minima for Better Generalization in Fine-Tuning Large Language Models and Beyond
Jiaxin Deng, Qingcheng Zhu, Junbiao Pang +3
Little research explores the correlation between the expressive ability and generalization ability of the low-rank adaptation (LoRA). Sharpness-Aware Minimization (SAM) improves mo…
