Conservative Meta-Agent Search: Architecture Adaptation under Non-Stationarity
Ali Atiah Alzahrani
Automated agentic-system design is typically evaluated on static task suites with immediate scalar rewards. Deployed systems face persistent shift, delayed dependent feedback, corr…
Verify Claims, Not Scores: Evidence-Based Verification of Modular Agents
Ali Atiah Alzahrani
When developers change one component of an agent, such as its controller, a learned model or its verifier, they usually judge the change by an aggregate task score. That score cann…
Say, Echo, Do: Strategic Narratives and Revealed Positioning in Financial Markets
Ali Atiah Alzahrani
Machine-learning signals built from financial text treat what institutions say, and what the media repeat, as evidence about value. But whoever shapes a narrative may be trading ag…
Multi-Agent Regime-Conditioned Diffusion (MARCD) for CVaR-Constrained Portfolio Decisions
Ali Atiah Alzahrani
We examine whether regime-conditioned generative scenarios combined with a convex CVaR allocator improve portfolio decisions under regime shifts. We present MARCD, a generative-to-…
Rough Path Signatures: Learning Neural RDEs for Portfolio Optimization
Ali Atiah Alzahrani
We tackle high-dimensional, path-dependent valuation and control and introduce a deep BSDE/2BSDE solver that couples truncated log-signatures with a neural rough differential equat…
