Out-of-Distribution Detection using Synthetic Data Generation

arXiv:2502.03323v2 Announce Type: replace-cross Abstract: Distinguishing in- and out-of-distribution (OOD) inputs is crucial for reliable deployment of classification systems. However, OOD data is typically unavailable or difficult to collect, posing a significant challenge for accurate OOD detection. In this work,…

Noisy-Pair Robust Representation Alignment for Positive-Unlabeled Learning

arXiv:2510.01278v1 Announce Type: new Abstract: Positive-Unlabeled (PU) learning aims to train a binary classifier (positive vs. negative) where only limited positive data and abundant unlabeled data are available. While widely applicable, state-of-the-art PU learning methods substantially underperform their supervised counterparts…

Morphlux: Transforming Torus Fabrics for Efficient Multi-tenant ML

arXiv:2508.03674v2 Announce Type: replace-cross Abstract: We develop Morphlux, a server-scale programmable photonic fabric to interconnect accelerators within servers. We show that augmenting state-of-the-art torus-based ML data-centers with Morphlux can improve the bandwidth of tenant compute allocations by up to 66%,…

ReTabAD: A Benchmark for Restoring Semantic Context in Tabular Anomaly Detection

arXiv:2510.02060v1 Announce Type: cross Abstract: In tabular anomaly detection (AD), textual semantics often carry critical signals, as the definition of an anomaly is closely tied to domain-specific context. However, existing benchmarks provide only raw data points without semantic context, overlooking…

Network-Level Vehicle Delay Estimation at Heterogeneous Signalized Intersections

arXiv:2510.01292v1 Announce Type: new Abstract: Accurate vehicle delay estimation is essential for evaluating the performance of signalized intersections and informing traffic management strategies. Delay reflects congestion levels and affects travel time reliability, fuel use, and emissions. Machine learning (ML) offers…
