Class DistributionSPL

  • public class DistributionSPL
    extends Distribution
    The smoothed power-law (SPL) distribution for the information-based framework that is described in the original paper.

    Unlike for DFR, the natural logarithm is used, as it is faster to compute and the original paper does not express any preference to a specific base. WARNING: this model currently returns infinite scores for very small tf values and negative scores for very large tf values

    WARNING: This API is experimental and might change in incompatible ways in the next release.
