Evaluating Global Measures of Network Centralization: Axiomatic and Numerical Assessments
Majid Saberi, Samin Aref
Network centralization, driven by hub nodes, impacts communication efficiency, structural integration, and dynamic processes such as diffusion and synchronization. Although numerou…
Discrete Optimization of Min-Max Violation and its Applications Across Computational Sciences
Cheikh Ahmed, Mahdi Mostajabdaveh, Samin Aref +1
We introduce the Discrete Min-Max Violation (DMMV) as a general optimization problem which seeks an assignment of discrete values to variables that minimizes the largest constraint…
LLM-Guided Evolution of Symbolic Acceleration Inequality Families for MILP
Milad Yazdani, Mahdi Mostajabdaveh, Samin Aref +1
Integer programming (IP) is central to many combinatorial optimization tasks but remains challenging due to its NP-hard nature. A practical way to improve IP solvers is to manually…
Troika algorithm: approximate optimization for accurate clique partitioning and clustering of weighted networks
Samin Aref, Boris Ng
Clique partitioning is a fundamental network clustering task, with applications in a wide range of computational sciences. It involves identifying an optimal partition of the nodes…
Robust Markov stability for community detection at a scale learned based on the structure
Samin Aref, Sanchaai Mathiyarasan
Community detection, the unsupervised task of clustering nodes of a graph, finds applications across various fields. The common approaches for community detection involve optimizin…
Enhancing Ultra-Low-Bit Quantization of Large Language Models Through Saliency-Aware Partial Retraining
Deyu Cao, Samin Aref
The growing use of large language models has raised environmental and economic concerns about their intensity of resource usage during inference. Serving these models to each user…
