LogicGaze: Benchmarking Causal Consistency in Visual Narratives via Counterfactual Verification
Rory Driscoll, Alexandros Christoforos, Chadbourne Davis
While sequential reasoning enhances the capability of Vision-Language Models (VLMs) to execute complex multimodal tasks, their reliability in grounding these reasoning chains withi…
MoE-DiffuSeq: Enhancing Long-Document Diffusion Models with Sparse Attention and Mixture of Experts
Alexandros Christoforos, Chadbourne Davis
We propose \textbf{MoE-DiffuSeq}, a diffusion-based framework for efficient long-form text generation that integrates sparse attention with a Mixture-of-Experts (MoE) architecture.…
Forgetting as a Feature: Cognitive Alignment of Large Language Models
Alexandros Christoforos
Large Language Models (LLMs) are often evaluated against ideals of perfect Bayesian inference, yet growing evidence suggests that their in-context reasoning exhibits systematic for…
SA-DiffuSeq: Addressing Computational and Scalability Challenges in Long-Document Generation with Sparse Attention
Alexandros Christoforos, Chadbourne Davis
Diffusion based approaches to long form text generation suffer from prohibitive computational cost and memory overhead as sequence length increases. We introduce SA-DiffuSeq, a dif…
Detection of Suicidal Risk on Social Media: A Hybrid Model
Zaihan Yang, Ryan Leonard, Hien Tran +2
Suicidal thoughts and behaviors are increasingly recognized as a critical societal concern, highlighting the urgent need for effective tools to enable early detection of suicidal r…
