A digital media service distributes digital media content to a plurality of devices in a graphical processing unit based distributed cluster and transmits executable instructions to these devices to initiate a collaborative filtering algorithm. Accordingly, the graphical processing unit in each of the devices, configured to utilize the collaborative filtering algorithm, may generate one or more co-occurrence vectors comprising similarities among a user's interactions with the digital media content and other users' interactions with the digital media content. These co-occurrence vectors are transmitted to the digital media service, which may create a matrix based at least in part on these vectors to determine personalized digital media content that is to be distributed to each of the devices in the distributed cluster. Accordingly, the personalized digital media content is distributed to each device in the distributed cluster.

Distributed processing for content personalization

A recommendation system uses artificial intelligence to identify, based on negative sentiment cues from users, item attributes, such as keywords, that users may find offensive or undesirable. The negative sentiment cues may be explicit (e.g., a user selects an option not to view a particular recommendation again), implicit (e.g., a user does not interact with recommendations relating to an attribute), or both. The system may use a computer model generated based on these identified attributes to filter or modify recommendations to a user or group of users. For instance, if a particular keyword is identified as highly offensive to a group of users, items associated with the keyword may be filtered from item recommendations presented to the group of users. If an attribute is identified as moderately offensive to a user, items associated with the attribute may be down-weighted in item recommendations presented to the user.

Artificial intelligence based identification of negative user sentiment in event data

A system that identifies attributes of an item depicted in an image using artificial intelligence is provided. For example, the system may use one or more deep belief networks (DBNs) or convolution neural networks (CNNs) trained to analyze images and identify attributes in items depicted in the images. A first artificial intelligence module may analyze an image to determine a type of item depicted in the image. The system may then select a second artificial intelligence module that is associated with the type of item and use the second artificial intelligence module to identify attributes in the item depicted in the image. Identified attributes, if associated with a confidence level over a threshold value, may be provided to a user. The user may provide feedback on the accuracy of the identified attributes, which can be used to further train the first and/or second artificial intelligence modules.
