      My Master's thesis: "Methods of detection and explanation of anomalies in time series". Based onCOIN (Contextual Outlier Interpretation) paper, which proposes a local method for explaining outliers,I created parallelized implementation of this method for time series - TS COIN. I thoroughly evaluatedTS COIN vs SHAP method for local outliers in time series setting and shown that TS COIN performedbetter in statistical tests.

Based onCOIN (Contextual Outlier Interpretation) paper, which proposes a local method for explaining outliers,I created parallelized implementation of this method for time series - TS COIN. I thoroughly evaluatedTS COIN vs SHAP method for local outliers in time series setting and shown that TS COIN performedbetter in statistical tests. I did an extensive detection method comparison of state-of-the-art sequentialdetectors against decision tree ensembles and optimization. Code implementation and all experiments are available in the pinned section on my GitHub profile. Tech stack: PyTorch, Fast.ai, TSAI, SHAP, Weights & Biases, Scikit-learn, XGBoost, Pandas, Python Show less
