Risk-Aware Information Theory
Hamidou Tembine
We develop a risk-aware information theory by replacing expectation with expectiles, introducing expectile entropy, divergence, and mutual information. These quantities exhibit beh…
Mitigating Polycentric Conflict-Trap Risk in Mali via Intergenerational Volterra Mean-Field-Type Games
Hamidou Tembine
Persistent instability in Mali and neighboring countries is not a temporary security crisis but a self-reproducing conflict system sustained by intergenerational grievances, climat…
The Risk Shadow of Principal Component Analysis: When 99.9999% Variance Preservation Causes Catastrophic Decision Errors
Hamidou Tembine
Principal Component Analysis (PCA) preserves variance, not the information needed to detect rare catastrophic events. This paper proves the existence of a {\it Risk Shadow}: PCA ca…
Causal Mirage Equilibrium in Agentic Machine Intelligence
Hamidou Tembine
Classical game-theoretic solution concepts assume that agents' internal representations remain causally linked to external states. In generative machine intelligence, this assumpti…
Achieving Generational Peace in Mali through Intergenerational Mean-Field-Type Game-based Incentives
Hamidou Tembine
This article develops an intergenerational mean-field-type game (MFTG) to model Mali's and neighbouring countries multi-actor conflict ecosystem, which includes formal state forces…
An Explicit Surrogate for Gaussian Mixture Flow Matching with Wasserstein Gap Bounds
Elham Rostami, Taous-Meriem Laleg-Kirati, Hamidou Tembine
We study training-free flow matching between two Gaussian mixture models (GMMs) using explicit velocity fields that transport one mixture into the other over time. Our baseline app…
