| SweetSpotSimilarity | A similarity with a lengthNorm that provides for a "plateau" of equally good lengths, and tf helper functions. For lengthNorm, A min/max can be specified to define the plateau of lengths that should all have a norm of 1.0. Below the min, and above the max the lengthNorm drops off in a sqrt function. For tf, baselineTf and hyperbolicTf functions are provided, which subclasses can choose between. |
