Mapping the Battlefield: Predicting Conflict Through Spatial Patterns
![The model unearthed patterns of fatality-mapped across longitude, latitude, and time using [latex]3D[/latex] sequences-in recent conflicts along the Kenya-Somalia border, successfully replicating similar spatiotemporal distributions of violence from historical data, and demonstrating an ability to identify recurring characteristics of conflict zones based on accumulated fatality counts within defined grid cells.](https://arxiv.org/html/2604.21067v1/x1.jpg)
A new approach analyzes the geometry of conflict – how violence unfolds in both space and time – to forecast fatalities with improved accuracy.
Smarter Flows: Guiding Max-Flow with Graph Neural Networks
![A graph convolutional network, initialized with edge flows, streamlines the Ford-Fulkerson algorithm for image segmentation, transforming a [latex]60 \times 60[/latex] pixel input and foreground/background seed points into a grid-like graph representation, ultimately yielding a min-cut segmentation through iteratively refined edge flows.](https://arxiv.org/html/2604.21175v1/algorithm_1.png)

![A novel learning architecture combines finite element methods with cross-attention transformers to establish mathematically guaranteed stability in long-term time series forecasting, leveraging a short training window and structure-preserving latent space embeddings to achieve parameter efficiency despite the inherent complexities of dynamic systems-a process where initial and continuity conditions are enforced via mortar variables across rollout domains and dynamics are prescribed as [latex]\ddot{u}=\mathcal{N}(u,\dot{u})[/latex].](https://arxiv.org/html/2604.21101v1/x1.png)
A novel framework blends the power of neural networks with established numerical methods to dramatically improve the stability and accuracy of long-term forecasting.
Reading the Market’s Signals: Predicting Liquidity Stress in Order Books
![During a build-up regime, gradual erosion of depth ([latex] -{14}.3 \pm 2.1 [/latex] units) and mild spread widening ([latex] +8.7 \pm 1.4 [/latex] units) consistently precede the onset of stress, explaining why flow-based detectors fail to capture early indications of instability due to persistent imbalance within the stable regime distribution.](https://arxiv.org/html/2604.20949v1/x1.png)
