Manifold-aware ranking kernel for information retrieval

A method of information retrieval programmed in a memory of a device comprising:

• a. receiving a search query input;
• b. performing a search based on the search query input and using a metric kernel learned by manifold-aware ranking kernel learning;
• and
• c. presenting a search result of the search.

An apparatus comprising:

• a. a non-transitory memory for storing an application, the application for:
• i. performing combined supervised kernel learning and unsupervised manifold kernel learning;
• and
• ii. generating a non-linear kernel model;
• and
• b. a processing component coupled to the memory, the processing component configured for processing the application.
