BALANCING PROVENANCE AND ACCURACY TRADEOFFS IN DATA MODELING |
| 摘要 |
Generating a data model may include receiving a raw data set and generating a first repository based on a first set of features of the raw data set, a second repository having a second set of features based on an aggregation of features of the first repository, and a third repository having a third set of features based on the first and second features sets. The data model may be generated based on a tradeoff between accuracy and provenance of the model. |

1. A computer implemented method for generating an analytics model, the method comprising:
receiving a data set having a defined first set of features; defining a second set of features based on an application of a set of domain knowledge data to the first set of features; generating a features hierarchy based on relationships between features of the first and second sets of features; and generating an analytics model based on a selection of features from the features hierarchy, wherein the analytics model includes a highest number of features of the second set of features while maintaining a defined accuracy value. |
