Abstract: Devices, systems, and methods are provided for using dynamic shipping options. A method may include receiving a request to add a first product to a virtual shopping cart of a first user; determining a first delivery fee for a first order comprising the first product; generating user interface data indicative of the first delivery fee and with which the first user may input a first offered delivery fee; presenting the user interface data; receiving a first user input indicative of the first offered delivery fee offered by the first user; determining that a coincident delivery fee discount based on the first order and a second order is less than a delivery fee threshold including delivery fee discounts of the first offered delivery fee and of a second offered delivery fee of the second order; initiating a first purchase of the first product a second purchase of the second product.

Abstract: System and methods are provided estimating long-term effects of system changes associated with a user interface without conducting long-term testing. In a first deployment region, a system change is released during a time period. A second deployment region does not have the system change released in the same time period. Historical data is received from both deployment regions associated with the time period. The user interface analysis system determines features from the historical data and determines a synthetic control sub-group from those features that correspond to features for a sub-group in the first deployment region. The user interface analysis system calculates a control outcome metric for the control sub-group and calculates an effect metric as a difference between a first outcome metric for the sub-group from the first deployment region and the control outcome metric.

Abstract: Techniques for reducing the latency of content retrieval from a content delivery network include receiving a request from a client device for media content, parsing the request for attributes associated with the request and the client device, and providing the attributes to a machine learning model to perform server-side prediction of an estimated retrieval time of the media content. A quality level for the media content is determined based on the estimated retrieval time, and the requested media content is provided to the client device at the determined quality level.

Abstract: A message to be transmitted is converted into an image file. The image file is stored and location information about a location where the image file is stored, is generated. The image file is transmitted to at least one device based on the location information.

Abstract: A method and apparatus for using a service provided by a universal plug and play (UPnP) device of a home network, based on a user interface (UI) received by a client located outside of the home network from a server for managing at least one UI for a remote access.
