Furthermore, the trained machine learning model is applied to the second values to determine a second margin.

Abstract: Technologies are shown for buyer initiated automatic seller account generation where a buyer client receives an identification of a purchase item, generates an item token corresponding to the purchase item, and provides the item token to a seller client. The seller client authenticates a seller user with an authentication service, such as a biometric authentication service, receives an authentication token corresponding to the seller user, and sends an account creation request with the item token and the authentication token to an account creation service. The account creation service receives the account creation request, sends a user information request to the authentication service with the authentication token and receives seller information for the seller user from the authentication service. The account creation service creates a seller user account using the seller information, commits a purchase transaction for the purchase item, and sends an item purchase confirmation to the buyer client.

Abstract: An experimentation platform controls testing of features by an application server. Based on a user identifier, the experimentation platform determines which feature should be provided, and the application server provides the corresponding version of a user interface. If the user behavior data shows that using a tested feature results in an improvement, the tested feature will be adopted. To determine whether or not an improvement is observed, a statistically significant amount of data is gathered. The experimentation platform gathers data regarding user behavior for the feature versions and, in response, adjusts the frequency at which each version is served. Providing the proposed version to an increased percentage of users decreases the total number of page serves required to gather statistically significant data. The experimentation platform may provide an updated projected time to completion of testing based on the changed percentage of users receiving the proposed version.

Abstract: Systems, methods, and computer program products for identifying a candidate product in an electronic marketplace based on a visual comparison between candidate product image visual content and input query image visual content.
