Learning from sanctioned government suppliers: a machine learning and network science approach to detecting fraud and corruption in Mexico

Medina-Hernández, M., Kertész, J. & Fazekas, M. (2026) Learning from sanctioned government suppliers: a machine learning and network science approach to detecting fraud and corruption in Mexico. Scientific Reports

Revisiting the Link between Politicians’ Salaries and Corruption.
