Non-textual topic modeling

Abstract:

Devices and techniques are generally described for non-textual topic modeling. In some examples, a first item of a plurality of items may be identified. A first ranked list of items from the plurality of items may be generated for the first item using collaborative filtering. Topic modeling input data representing associations between the first item and each item in the first ranked list may be generated. Second data may be generated by inputting the topic modeling input data into a topic modeling algorithm. The second data may comprise one or more topics for the first ranked list of items.
