This paper introduces TAMUSA-Chat, a research-oriented framework that enables academic institutions to build responsible, domain-adapted conversational AI systems through supervised fine-tuning, retrieval-augmented generation, and systematic evaluation, while providing a publicly available codebase to support reproducible experimentation and ethical deployment.
This study evaluates the robustness and pedagogical safety of offline large language models for Turkish heritage language education using a custom anomaly suite, finding that reasoning-oriented models in the 8B–14B parameter range offer the optimal balance between cost and safety while demonstrating that anomaly resistance is not strictly dependent on model scale.
This paper provides a theoretical framework explaining how Large Language Models achieve semantic prompt comprehension, In-Context Learning, and Chain-of-Thought reasoning by inferring transition probabilities, reducing prompt ambiguity, and decomposing complex tasks into simpler sub-problems, respectively, thereby offering novel insights into the statistical superiority of advanced prompt engineering techniques.
This paper introduces LatamQA, a geographically informed sociocultural bias dataset of over 26,000 multilingual multiple-choice questions derived from Wikidata and Wikipedia, which reveals that current large language models exhibit significant performance disparities across Latin American countries, favoring Iberian Spanish culture and their original training languages.
This paper introduces SpreadsheetArena, a platform for evaluating large language models' end-to-end spreadsheet generation capabilities through blind pairwise comparisons, revealing that while models can produce functional workbooks, they often fail to align with domain-specific best practices and that user preferences vary significantly across different use cases.
This paper challenges the assumption that LLM deception is coextensive with lying by demonstrating that models can successfully deceive through misleading non-falsities that current truth probes fail to detect, thereby revealing a critical blind spot in mechanistic deception detection.
The GATech team's approach to the AbjadGenEval shared task utilized a fine-tuned multilingual E5-large encoder with simple mean pooling to achieve an F1 score of 0.75 for detecting AI-generated Arabic text, finding that this stable baseline outperformed complex pooling strategies likely due to data limitations and a distinct length difference between human-written and machine-generated texts.
This paper demonstrates that fine-tuned bidirectional encoders, specifically a hybrid AraBERTv2 architecture, significantly outperform large-scale causal decoders in the challenging task of 82-class Arabic medical text classification by better capturing global semantic context despite data imbalance and label noise.
This paper introduces Personalized Group Relative Policy Optimization (P-GRPO), a novel framework that improves alignment with diverse individual preferences by decoupling advantage estimation from batch statistics and normalizing rewards against preference-group-specific histories, thereby overcoming the limitations of standard GRPO in handling heterogeneous user signals.
This paper addresses the regulatory ambiguity surrounding "AI models" and "AI systems" by proposing clear conceptual and operational definitions that distinguish trained parameters from broader system components, thereby facilitating the precise allocation of obligations across the AI value chain.
LWM-Temporal is a task-agnostic foundation model for wireless channels that leverages a novel Sparse Spatio-Temporal Attention mechanism and physics-informed pretraining to learn universal, geometry-consistent embeddings, achieving superior performance in channel prediction across diverse mobility regimes with limited fine-tuning data.
HTM-EAR is a hierarchical tiered memory system that combines HNSW-based working memory with archival storage, importance-aware eviction, and hybrid routing to effectively preserve essential information and maintain high retrieval precision under sustained saturation, significantly outperforming traditional LRU approaches while approaching the performance of unbounded oracle memory.
Tureis is a self-supervised, Transformer-based framework designed for edge deployment in smart homes that achieves fine-grained, multi-failure sensor localization by encoding heterogeneous sensor streams into compact features and using a masked reconstruction objective to identify faulty devices without requiring labeled data or human intervention.
This paper evaluates how autonomous cyber attack agents generalize to unseen IP reassignments in enterprise networks, finding that while prompt-driven LLM agents achieve the highest success rates compared to traditional RL and adaptation methods, they incur significant costs in computational efficiency, transparency, and reliability due to issues like repetition loops.
This large-scale controlled study reveals that evaluation format (multiple-choice vs. open-ended) and specific model-scaffold interactions, rather than scaffold architecture alone, are the primary drivers of measured safety differences in language models, ultimately demonstrating that no universal safety ranking exists across different deployment configurations.
This paper proposes a parameter-efficient continual learning framework for Human Activity Recognition that mitigates catastrophic forgetting in domain-incremental scenarios by employing channel-wise gated modulation to adapt frozen pretrained representations through bounded diagonal scaling, thereby achieving superior stability and plasticity with minimal parameter updates.
This paper introduces eXplicit Sharpness-Aware Minimization (XSAM), a novel and computationally efficient framework that improves upon existing SAM implementations by providing a more faithful interpretation of the ascent gradient and explicitly estimating the direction toward local loss maxima to achieve superior generalization.
This paper introduces \texttt{InFusionLayer}, a novel, open-source Python ensemble tool inspired by Combinatorial Fusion Analysis (CFA) that integrates rank-score characteristic functions and cognitive diversity to enhance multiclassification performance across PyTorch, TensorFlow, and Scikit-learn workflows.
This paper addresses the failure of byte-sequence-based masked modeling in encrypted traffic classification by identifying a mismatch in inductive bias and proposing FlowSem-MAE, a protocol-native tabular masked autoencoder that leverages field-specific semantics and temporal patterns to significantly outperform existing methods with substantially less labeled data.
OmniGuide is a universal framework that enhances the performance of generalist Vision-Language-Action (VLA) policies on complex tasks by integrating diverse guidance sources—such as 3D foundation models and human pose estimators—into a unified differentiable energy field that guides action sampling through task-specific attractors and repellers.
