Neural Spline Flows Aid Dark Matter Search in CMS Data.
Key takeaways
- Neural Spline Flows are applied to model signal and background densities in dark matter searches.
- The method uses a likelihood-ratio test statistic for broad kinematic sensitivity.
- Upper limits on dark matter signal strengths were set using CMS open data.
- Background modeling discrepancies impacted the observed limits.
Who benefits
Summary
This paper reports a search for dark matter produced with a leptonically decaying Z boson using CMS Run 2015D open data and Neural Spline Flows. The method models signal and background densities to set upper limits on signal-strength parameters for various dark matter mediators, though observed limits are weaker than expected due to background modeling discrepancies.

Emotional Preferences Regulate Goal Priorities in Reinforcement Learning Agents
This paper proposes a computational framework where higher-level goals autonomously generate state-dependent emotional preferences to regulate the priorities of competing lower-level objectives in reinforcement learning agents. It demonstrates how this emergent preference function exhibits contextual priority switching and improves performance over fixed-preference strategies in multi-objective exploration environments.
New Framework Unifies Task Detection and Adaptation for Continual Learning
This paper proposes FiUni, a Fisher-guided unified framework for task-free continual learning in LLMs that combines batch-level task detection with parameter-efficient adaptation. FiUni uses Fisher information matrix (FIM) properties to dynamically determine whether to reuse, expand, or create new low-rank adaptation (LoRA) subspaces, effectively mitigating catastrophic forgetting without explicit task boundaries.
