An Irregular Time-Aware Deep Learning Pipeline for Early Sepsis Prediction in Sparse ICU Trajectories

This study proposes a Time-Decay Gated Recurrent Unit (TD-GRU) model that confines temporal decay to the hidden state to preserve raw clinical values, demonstrating statistically credible net clinical benefit and superior performance over several baselines for early Sepsis-3 prediction in sparse, irregularly sampled ICU trajectories.

Event Detection in Social Networks Using Polarization Dynamics

This paper proposes a polarization-based anomaly detection method using the Minimum Effort to Consensus (MEC) index on social media data, demonstrating that monitoring shifts in public disagreement outperforms traditional volume-based approaches in identifying significant events, as validated through a case study of the 2024 Colombian pension reform debate on X.
