Using Non-Lipschitz Signum-based Functions for Distributed Optimization and Machine Learning: Trade-off Between Con-vergence Rate and Optimality Gap
Mohammadreza Doostmohammadian, Amir Ahmad Ghods, Alireza Aghasi +2
In recent years, the prevalence of large-scale data-sets and the demand for sophisti-cated learning models have necessitated the development of efficient distributed ma-chine learn…
MonoVoc: Decoupling Geometry and Semantics for Lightweight Monocular Open-Vocabulary 3D Gaussians
Pouya Ardekhani, Zahra Dehghanian, Morteza Abolghasemi +1
The paper introduces a training‑free pipeline that separates 3D geometry reconstruction from semantic labeling to create compact, object‑level semantic maps from a single monocular…
GTIN: A Unified Framework for Joint Event and Time Prediction in Temporal Graphs
Mohammad Ostadmohammadi, Sepehr Kazemi, Hamid R. Rabiee
Temporal graphs are increasingly used to model dynamic systems in diverse domains such as social networks, financial networks, and traffic networks. Predicting both what the next e…
Teacher-Student Structure for Domain Adaptation in Ensemble Audio-Visual Video Deepfake Detection
Elham Abolhasani, Maryam Ramezani, Hamid R. Rabiee
The rapid advancement of generative AI models is leading to more realistic deepfake media, encompassing the manipulation of audio, video, or both. This raises severe privacy and so…
