Topological and Geometric Data Analysis
Abstract
This paper proposes a novel approach to Neural Architecture Search (NAS) termed Dynamic Topological Adaptive NAS (DTANAS), which leverages concepts from topological data analysis and physical systems to achieve more efficient and robust architecture optimization. The core idea is to model the search space as a complex topological network, allowing for dynamic changes in architecture during the training process. We introduce a framework where architectural modifications are viewed as topological transformations, induced by random perturbations and feedback mechanisms. These mechanisms mimic the adaptive behavior observed in physical systems undergoing evolution and self-organization. The system employs an evolutionary or reinforcement learning strategy to evaluate and refine the 'topological quality' of the network architecture. Unlike traditional NAS methods that rely on static search spaces and gradient information, DTANAS offers a fundamentally different perspective, potentially leading to architectures that are more resilient to noise and better suited for complex, evolving tasks. This work presents a theoretical framework and a computational approach to explore this paradigm, demonstrating the potential for significant improvements in NAS efficiency and architectural quality.
Model-based life-cycle evaluation indicates that AI-optimized PPP contracts reduce bridges reaching emergency condition by 30%–40% over a 30-year horizon while lowering life-cycle costs by 8%–12% compared with rule-based policies, providing infrastructure agencies and private concessionaires with an integrated AI-driven life-cycle management platform.

This paper presents a two-wheeled mobile robot trajectory-tracking controller combining a particle swarm optimization (PSO)-tuned fuzzy logic controller (FLC) with a residual reinforcement learning (RL) correction layer.PSO tuning reduces the global distance error by 35% and the integral absolute error by 44% over the initial FLC.The residual RL layer further reduces the global distance error by approximately 2.3% and improves cornering-region tracking by 3.9% in RMSE, 4.7% in IAE, and 5.2% in peak distance error.The proposed controller also reduces the global distance error by 41% and 66% relative to independently tuned PID and fuzzy-PID baselines.Trained across four trajectory families with a held-out test split, the generalized agent reduces the average test distance error by 18% relative to the tuned FLC baseline.These results show that a lightweight residual correction improves both accuracy and generalization while preserving the fuzzy controller's interpretability.
