Neural network based position estimation of target object of interest in video frames
Visual target tracking is task of locating a target in consecutive frame of a video. Conventional systems observe target behavior frames of the video.

Collaborative-filtered content recommendations with justification in real-time
Collaborative-filtered content recommendations with justification in real-time is described. A recommendation system determines these recommendations, in part, by identifying digital content items of a catalog that are associated with a single attribute used to describe digital content. The attribute used for the identification is based on affinity scores computed for a client device user to which the recommendations are being provided. These affinity scores indicate the client device user's affinity for different attributes used to describe the digital content. Once the digital content items are identified based on the one attribute, the recommendation system is then limited to ranking and selecting from the identified digital content items to provide the recommendations. The recommendation system does not process the entire catalog of digital content items at once to rank and select the items. Due to this, the described recommendation system performs less computing and is therefore faster than conventional recommendation systems. |

Selecting a host based on quality of stored data
A database node selects one of a number of database mirror hosts to perform a database read query. In theory, mirror hosts store redundant database entries.
