The Euclidean distance uses the cubes of the distances along the individual dimensions.
- True
- False
When using the Euclidean distance to measure similarity we often encounter features with different ranges. Which of the following actions should be taken in this situation?
- Remove all features with very small ranges.
- Do nothing.
- Scale the ranges of the features.
- Remove all features with very large ranges.
Which of the following is often used in feature selection to reduce the dimensional of a similarity problem?
- The scale of the feature.
- Remove binary type features.
- Remove decimal type features.
- Remove integer type features.
- Domain knowledge.
When performing similarity measurements amongst non-numeric features, a common practice is to first try to order the values of the non-numeric features. What can be said of the resulting ordinal values?
- They can be only used in exact equality similarity measurements.
- They can be used to perform exact and relative similarity measurements.
- They are useless.
