Terms used throughout the curriculum
These definitions reflect how each term is used in the context of ML-driven portfolio construction - not their broadest possible meaning in finance or computer science.
- Cluster
- A group of assets whose return and volatility behavior is more similar to each other than to assets in other groups, as determined by the chosen distance metric and algorithm.
- Silhouette Score
- A value between -1 and 1 measuring how well each asset fits its assigned cluster relative to neighboring clusters. Scores above 0.4 generally indicate meaningful structure.
- Walk-Forward
- A backtesting method where the model is retrained on each new training window and evaluated on the immediately following out-of-sample period - mimicking real deployment conditions.
- Rebalancing
- The periodic process of adjusting portfolio weights to match updated cluster assignments, typically triggered on a fixed schedule (weekly, monthly) or when cluster membership shifts by more than a defined threshold.
- Feature Space
- The multi-dimensional representation of each asset built from engineered inputs - correlation, volatility, drawdown - that the clustering algorithm uses to compute pairwise distances.
- Auto Trading Bot
- A software system that executes portfolio rebalancing decisions automatically based on signals generated by the ML pipeline, without requiring manual order entry at each rebalancing event.
