A Dual-Head Model for Host based Intrusion Detection on System-Call traces

Host-based intrusion detection systems (HIDS) need to detect both unseen exploits from day one and recurring known attack families. Maintaining separate anomaly-detection and supervised-classification frameworks increases the computational and operational footprint — a cost that only a few embedded or edge devices can...

ChronoFlow: Hierarchical Flow Matching for Irregular Time Series Generation

Recent advances in generative modeling have substantially improved time series generation, yet most existing methods either assume a regular temporal grid or focus on feature dynamics under a given sampling structure. This makes them illsuited for generating irregular time series in their native form, where a model mus...
