A team from MIT has developed an algorithm to identify causal links in complex systems by measuring interactions between variables over time.
The versatile algorithm identifies variables that likely influence others in complex systems. This method analyzes data collected over time to measure interactions between variables and estimate the impact of changes in one variable on another. It generates a "causality map" showing which variables are strongly linked.
The algorithm distinguishes between different types of causality:
- **Synergistic:** A variable only influences another when paired with a second variable.
- **Redundant:** A change in one variable has the same effect as another variable.
The algorithm also estimates "causal leakage," indicating that some unknown influence is missing.
