Techopedia explains Data Augmentation
Data augmentation is of the last steps done in enterprise data management after monitoring, profiling and integration.
Some of the common techniques used in data augmentation include:
Extrapolation Technique: Based on heuristics. The relevant fields are updated or provided with values.
Tagging Technique: Common records are tagged to a group, making it easier to understand and differentiate for the group.
Aggregation Technique: Using mathematical values of averages and means, values are estimated for relevant fields if needed
Probability Technique: Based on heuristics and analytical statistics, values are populated based on the probability of events.
