Value of Information-Enhanced Exploration in Bootstrapped DQN

arXiv:2511.02969v2 Announce Type: replace Abstract: Efficient exploration in deep reinforcement learning remains a fundamental challenge, especially in environments characterized by high-dimensional states and sparse rewards. Traditional exploration strategies that rely on random local policy noise, such as $epsilon$-greedy and Boltzmann…

ManifoldFormer: Geometric Deep Learning for Neural Dynamics on Riemannian Manifolds

arXiv:2511.16828v1 Announce Type: new Abstract: Existing EEG foundation models mainly treat neural signals as generic time series in Euclidean space, ignoring the intrinsic geometric structure of neural dynamics that constrains brain activity to low-dimensional manifolds. This fundamental mismatch between model…

Analysis of heart failure patient trajectories using sequence modeling

arXiv:2511.16839v1 Announce Type: new Abstract: Transformers have defined the state-of-the-art for clinical prediction tasks involving electronic health records (EHRs). The recently introduced Mamba architecture outperformed an advanced Transformer (Transformer++) based on Llama in handling long context lengths, while using fewer…

Interactive Query Answering on Knowledge Graphs with Soft Entity Constraints

arXiv:2508.13663v2 Announce Type: replace-cross Abstract: Methods for query answering over incomplete knowledge graphs retrieve entities that are emph{likely} to be answers, which is particularly useful when such answers cannot be reached by direct graph traversal due to missing edges. However,…

Provably Minimum-Length Conformal Prediction Sets for Ordinal Classification

arXiv:2511.16845v1 Announce Type: new Abstract: Ordinal classification has been widely applied in many high-stakes applications, e.g., medical imaging and diagnosis, where reliable uncertainty quantification (UQ) is essential for decision making. Conformal prediction (CP) is a general UQ framework that provides…

Sex and age determination in European lobsters using AI-Enhanced bioacoustics

arXiv:2511.16848v1 Announce Type: new Abstract: Monitoring aquatic species, especially elusive ones like lobsters, presents challenges. This study focuses on Homarus gammarus (European lobster), a key species for fisheries and aquaculture, and leverages non-invasive Passive Acoustic Monitoring (PAM). Understanding lobster habitats,…
