About Marina Sokolova
In 2018, Marina Sokolova led the development of the 'AdaptiBoost' framework at Skolkovo Institute, a gradient-boosting variant explicitly designed for sparse, high-frequency sensor data from Russian industrial IoT deployments, where missing values and timestamp misalignment crippled standard implementations. Unlike most algorithm designers who optimize for benchmark accuracy, she prioritized interpretability under operational constraints: her team embedded real-time SHAP approximation directly into the inference pipeline, enabling factory engineers without ML training to diagnose model drift during turbine vibration monitoring. Her 2021 paper on adversarial robustness in time-series forecasting, tested on actual Gazprom Neft refinery telemetry, demonstrated how small, physically plausible perturbations could cascade into false shutdown signals, prompting revised API safety thresholds across three industrial control systems. She speaks often about the 'weight of silence' in datasets: not just missing entries, but the deliberate omission of contextual metadata like maintenance logs or ambient temperature shifts that fundamentally alter feature importance.
