System classifies metaphorical violence on cable news.
New method detects psychosocial factors linked to gang violence on social media.
Machine learning improves risk assessment for gender-based violence victims.
While the costs of human violence have attracted a great deal of attention from the research community, the effects of the network-on-network (NoN) violence popularised by Generative Adversarial Networks have yet to be addressed. In this work, we quantify the financial, social, spiritual, cultural, grammatical and derm…
We first pursue the study of how hierarchy provides a well-adapted tool for the analysis of change. Then, using a time sequence-constrained hierarchical clustering, we develop the practical aspects of a new approach to wavelet regression. This provides a new way to link hierarchical relationships in a multivariate time…
The July Revolution in Bangladesh was fueled by state violence, which paradoxically strengthened the movement.
Paper proposes a framework to analyze DV on social media.
Domestic violence (DV) is a global social and public health issue that is highly gendered. Being able to accurately predict DV recidivism, i.e., re-offending of a previously convicted offender, can speed up and improve risk assessment procedures for police and front-line agencies, better protect victims of DV, and pote…
Neural networks improve scalability for agent-based modeling demonstrations.
We model anomaly and change in data by embedding the data in an ultrametric space. Taking our initial data as cross-tabulation counts (or other input data formats), Correspondence Analysis allows us to endow the information space with a Euclidean metric. We then model anomaly or change by an induced ultrametric. The in…
This study predicts crime trends in Denver using machine learning.
Networks play a central role in modern data analysis, enabling us to reason about systems by studying the relationships between their parts. Most often in network analysis, the edges are given. However, in many systems it is difficult or impossible to measure the network directly. Examples of latent networks include ec…
I present a unified discussion of several recently published results concerning the escalation, timing and severity of violent events in human conflicts and global terrorism, and set them in the wider context of real-world and cyber-based collective violence and illicit activity. I point out how the borders distinguish…
Anti-ELAB protests affected Hong Kong firms' stock prices, especially those linked to pan-democrats.
Study analyzes homicide rates in Goias, Brazil, using clustering methods.
We examine random variables in the power law/regularly varying class with stochastic tail exponent, the exponent having its own distribution. We show the effect of stochasticity of on the expectation and higher moments of the random variable. For instance, the moments of a right-tailed or right-asymmetric varia…
SLIM model predicts social network polarization using signed links.
A new active learning method for skewed data sets.
High and volatile global food prices have led to food riots and played a critical role in triggering the Arab Spring revolutions in recent years. The severe drought in the US in the summer of 2012 led to a new increase in food prices. Through the fall, they remained at a threshold above which the riots and revolutions …
