"description": "ChaosNetBench-CML is a benchmark dataset and evaluation framework for spatiotemporal forecasting on coupled standard map lattices spanning the full K-parameter range from ordered to hyperchaotic regimes. It is designed to evaluate whether spatial-graph-aware architectures outperform temporal baselines under varying degrees of spatiotemporal coupling, as characterised by the ratio rho = epsilon / K.",

"rai:dataLimitations": "ChaosNetBench-CML covers a single Hamiltonian lattice family based on the Coupled Standard Map. Results may not generalise to dissipative systems, continuous-time chaotic flows (e.g. High-Dimensional Coupled Oscillators), or spatiotemporal PDEs. The benchmark measures autoregressive rollout quality; it does not assess long-time statistical properties (invariant measures, Lyapunov spectra). The IC-based train/test split does not test out-of-distribution generalisation across K or rho values.",
"rai:dataBiases": "All trajectories are generated synthetically from a deterministic dynamical system with a fixed pseudo-random seed scheme (hash-based per configuration). There is no human annotation, demographic data, or selection bias in the conventional sense. The parameter grid (K, rho, N) was chosen to span known dynamical regime boundaries; denser sampling in the mixed-phase region K~0.97 is intentional and reflects scientific interest rather than inadvertent bias.",
"rai:personalSensitiveInformation": "None. The dataset contains only numerically simulated trajectory data from a mathematical dynamical system. No human subjects, personal information, or sensitive attributes are present.",
"rai:dataUseCases": "Intended uses: (1) Benchmarking spatiotemporal forecasting models under controlled chaos. (2) Evaluating whether graph-topology-aware architectures improve over temporal-only baselines in coupled chaotic systems. (3) Studying model behaviour as a function of the chaos parameter K and coupling ratio rho. Not recommended for: training ML models for real physical prediction tasks without further validation; use as a general time-series benchmark where the chaotic structure is not relevant.",
"rai:dataSocialImpact": "Positive: provides a reproducible, physics-grounded benchmark that enables fair comparison of ML forecasting models. Facilitates scientific transparency. Risks: minimal, since the data is synthetic and the subject matter (discrete dynamical systems) has no direct adverse societal application. No known misuse vectors.",

Initial conditions are drawn uniformly in [0, 2pi) x (-pi, pi) per site with hash based per-configuration seeds (base_seed=42). SALI orbit classification is computed using 1000 tangent map iterations with early termination at SALI < 1e-8. The code is publicly available at https://github.com/htmoges/ChaosNetBench."
