Abstract: The systems, methods, and computer program products for determining bins for a data model are provided. Variables in a training data set are binned into bins up to a configurable number of bins. Variables in the validation data set are also binned using the bins from the training data set. A first decision tree is generated using the bins and the binned variables from the training data set and is pruned. A second decision tree is generated using the structure of the first decision tree and the binned variables from the validation data set. The first and second decision tree are merged into a third decision tree. Leaf nodes of the third decision tree are sorted and merged until weights of evidence associated with the training data set and the validation data set are monotonic. The bins for the data model are determined from the merged leaf nodes.

Abstract: A small cell interference coordination method and wireless communication device includes obtaining mobile information of at least one of the small cells. Relative movement between the small cells is determined according to at least the movement information. A Doppler frequency shift of a signal between small cells is estimated according to the relative movement. An interference alignment policy between small cells is implemented according to the estimated Doppler frequency shift.
