Talk Title: Causal Dependencies in Multivariate Time Series
Abstract: The talk starts with a motivation for casual analysis. Correlation does not imply causation. Similarly, lack of correlation does not imply lack of causation. How can we detect causality in complex systems such as telecom networks? The talk covers 3Wh of Causality (What, why, where). It covers taxonomy of time series casual discovery, an overview of the methods and techniques such as Granger causality, Convergent Cross Mapping, information theoretic approaches, graphical approaches and ML approaches. How can we connect any observed event to possibly a set of specific causal events? Why do we need counterfactual interventions for causal intensity? The talk describes the relevance of causality in telecom domain and cover a few use cases in telecom such as Key Performance Indicator (KPI) degradation and outlier root cause analysis and hardware failures. The speaker will share sample results from simulated experiments. He will introduce a few active research topics in this space.
