Forgotten Words: Benchmarking NeoBERT for Dementia Detection in Low-Resource Conversational Filipino and English Speech

This paper presents the first systematic evaluation of transformer-based dementia detection in Filipino-English code-switched speech, demonstrating that while monolingual models fail to generalize across languages, bilingual fine-tuning effectively eliminates cross-lingual performance degradation and achieves high accuracy regardless of model architecture.

Learning in Low-Dimensional Subspaces: Orthogonal Bottlenecks for Reinforcement Learning

This paper introduces orthogonal bottlenecks, a lightweight, architecture-agnostic mechanism that constrains reinforcement learning representations to low-dimensional subspaces via fixed orthonormal projections, demonstrating both theoretically and empirically that task-relevant value functions can be preserved and often improved upon with minimal dimensionality while stabilizing feature geometry.

Geometric Workspace Analysis and Transmission-Aware Dynamics of a Serial Spherical Tool for Microsurgery

This paper presents a kinematic and transmission-aware design framework for a serial spherical microsurgical tool, featuring an analytical workspace formulation and a dynamics-informed methodology for self-locking transmissions, which are validated through experiments on a purpose-built robotic system for vitreoretinal surgery.

Cross-Domain Generalization Limits of Vision Foundation Models in Facial Deepfake Detection

This paper systematically evaluates the cross-domain generalization limits of Vision Foundation Models in facial deepfake detection, revealing that while these models excel at identifying full-face synthesis, they struggle with localized editing techniques due to inherent trade-offs between pre-training paradigms and linear probe evaluation structures.

Scaling up Energy-Aware Multi-Agent Reinforcement Learning for Mission-Oriented Drone Networks with Individual Reward

This paper proposes an energy-aware Multi-Agent Reinforcement Learning model utilizing Deep Q-Networks with individual reward functions to enhance the robustness, energy efficiency, and success rate of mission-oriented drone networks, particularly when scaling up environment size and agent numbers compared to traditional shared reward approaches.

Test-Time Graph Search for Goal-Conditioned Reinforcement Learning

This paper introduces Test-Time Graph Search (TTGS), a lightweight, training-free planning wrapper that leverages the inherent geometric structure of existing offline goal-conditioned RL policies to dramatically improve success rates on long-horizon tasks without requiring additional supervision or parameter updates.

Hedging Options on Asset Portfolios against Just One Underlying Asset in the Presence of Transaction Costs

This study investigates the optimal hedging strategy for options on a two-asset portfolio when transaction costs are present, demonstrating through simulation that hedging with a correlated but non-underlying asset can be preferable to hedging with the correct asset if the correlation is sufficiently high and transaction costs are low, as determined by risk-adjusted value metrics.

Do Synthetic Brain MRIs Reliably Improve Tumour Classification? A StyleGAN2-ADA Class-Plane Augmentation Study on BRISC 2025

This study demonstrates that while StyleGAN2-ADA-generated synthetic brain MRIs do not universally improve tumor classification across all model architectures, they provide a statistically significant accuracy boost for MobileViTV2 when using feature-space filtering at a 1:1 real-to-synthetic ratio, highlighting that augmentation utility depends on the specific classifier and data configuration rather than visual fidelity alone.
