Political Geography and Stock Market Volatility: The Role of Political Alignment Across Sentiment Regimes

Scottish Journal of Political Economy, Volume 73, Issue 1, February 2026.
ABSTRACT We study the nexus between political geography and stock market volatility by examining the interrelation between political geography and the predictive relation between the state‐ and aggregate‐level stock market volatility via recently constructed measures of political alignment.

Joint Topology Learning and Latent Input Identification Using Spatio-Temporally Linear Structured SEM

Mathematics
Topology identification and signal inference are cornerstone tasks in graph signal processing (GSP). Structural Equation Modeling (SEM) is particularly effective for network inference as it explicitly captures causal dependencies.

An FDA-MIMO radar 2-D parameter estimation algorithm based on graph signal processing

Remote Sensing Letters
To improve the range-angle estimation accuracy of frequency diverse array multiple Input multiple output (FDA-MIMO) radar at low SNR, this letter proposes a joint estimation algorithm of FDA-MIMO radar target range-angle based on graph signal processing (

Nonintrusive load disaggregation by fusion of graph signal processing and CNN

Journal of Physics: Conference Series
Nonintrusive load disaggregation techniques play a pivotal role in power system planning and decision making for demand response. The sparsity of low frequency total power data features, coupled with the model’s challenge in effectively extracting and ...

Anomalous Sound Detection For Road Surveillance Based On Graph Signal Processing

European Signal Processing Conference
Recently, Anomalous Sound Detection (ASD) has emerged as a promising method for road surveillance. However, since the ratio of anomalous events is generally too small, anomaly detection in general, and ASD in particular, are mainly treated as one-class ...

Time-varying graph learning from smooth and stationary graph signals with hidden nodes

EURASIP Journal on Advances in Signal Processing
Learning graph structure from observed signals over graph is a crucial task in many graph signal processing (GSP) applications. Existing approaches focus on inferring static graph, typically assuming that all nodes are available.
