Abstract: Embodiments of the invention provide a technical solution by generating a value index score based on aggregation of a value from a combination of features as a unit. In one embodiment, instead of generating a value index score based on a collection of features with each feature being a discrete parameter, aspects of the invention generate the value index score while accounting for weights of a combination of features as a unit. Furthermore, embodiments of the invention generate a weight value for each feature and that the weight, not only will it be a factor in the calculation, but also be modifiable in response to other factors of the features.
