A method includes determining a plurality of epochs from a timeline of an experiment, wherein each of the plurality of epochs corresponds to a constant traffic allocation. The method further includes calculating, by a processing device, first and second mean values corresponding to a baseline of the experiment and a variation of the experiment for each epoch, respectively. The method further includes determining, for each epoch, a difference between the first mean value and the second mean value to generate a plurality of differences. The method further includes calculating, by the processing device, a weighted sum of the plurality of differences to generate a final difference in mean values.

Statistics acceleration in multivariate testing

A variation testing system for performing variation testing of content is disclosed. The variation testing system allows an experimenter to continuously monitor the results of the variation test. In order to ensure that the experimenter is provided with valid results, the variation testing system may reset the variation test.

Implementing a reset policy during a sequential variation test of content

Systems, devices, and methods are provided for rendering images of hair using a statistical light scattering model for hair that approximates ground truth physical models. The model is significantly faster than other implementations of the Marschner hair model. The statistical light scattering model includes all the features of Marschner such as eccentricity for elliptical cross-sections, and extends them by adding azimuthal roughness control, consideration of natural fiber torsion, and full energy preserving. Adaptive Importance Sampling (AIS) is specialized to fit easily sampled distributions to bidirectional curve scattering density functions (BCSDFs) of the model.
