Persistent Structural Inequality of Online Interactions Across Platforms

Collection of recent arXiv papers (CS / Social and Information) examining structural and methodological issues in networked social systems. Key findings include: persistent, platform-independent inequality in online interactions (stable power-law-like concentration of attention); substantial bias introduced by sparse GPS mobility trajectories in epidemic models and a proposed inverse-probability-weighting correction; use of Weak Form SINDy (WSINDy) to learn effective ODE models from networked stochastic dynamics and sensitivity to trajectory/noise counts; experimental evidence that different噪声
