Abstract: Technologies are disclosed for determining validity of data obtained from an A/B experiment, where the experiment evaluates the desirability of a potential change at a website. The experiment is run for a period of time and based upon an expected allocation of users into the A group (control group) and the B group (e.g., treatment group), along with an actual number of users directed into the two groups, it is determined if a minimal detectable error of allocation has been exceeded and, if it has, the data is deemed to be invalid. If not, the data is deemed to be valid.

Abstract: Devices and techniques are generally described for providing a graphical user interface. In some examples, first image data may be sent to a computing device, that when rendered is effective to display a first combination of items disposed together in a first environment and a first selectable control. In some examples, first data may be received indicating a selection of the first selectable control. In various examples, a first computing device may determine first feature data representing the first image data. In some examples, the first computing device may determine second image data using the first feature data. In some examples, the second image data may be sent to a second computing device. The second image data, when rendered, may be effective to display a second combination of items disposed together in a second environment.
