Abstract: Content items are recommended based on a ranking of the content items, where the ranking is based on output of a trained ranking model. The ranking model is trained using ranking loss that is based weightings of pairwise rankings of pairs of training content items selected from a set of training content items, wherein each weighting of a pairwise ranking represents a probability of receiving a negative response to a recommended content item if the pair of the pairwise ranking is misordered in a ranking of the set of training content items.

Abstract: A method, apparatus, and system for calibration of a media processing device are provided. The method may include providing a calibration sub-routine where the calibration sub-routine includes a plurality of calibration operations to be performed in sequence. The method may further include associating an audible note with each calibration operation and generating the audible note for each calibration operation as each respective calibration operation is performed, where the audible note is generated by a frequency of operation of a motor. The audible note associated with one calibration operation may be different from the audible note associated with another calibration operation.

Abstract: Techniques for delivering a video message from a purchaser of an order to a recipient of the order are described. An order for one or more items is received, the order specifying a recipient and having an association with a purchaser. The order further specifies to deliver a video message from the purchaser to the recipient. Embodiments receive a video message from the purchaser. The order for the one or more items is fulfilled. Embodiments transmit at least an indication of the video message to the recipient.
