The present invention is related to a system and method of caching data
employing probabilistic predictive techniques. The system and method
provides local storage of a subset of available viewing selections by
assigning a value to a selection and retaining selections in the cache
depending on the value and size of the selection. The value assigned to
an item can represent the time-dependent likelihood that a user will
review an item at some time in the future. An initial value of an item
can be based on the user's viewing habits, the user's viewing habit over
particular time segment and/or viewing habits of a group of user's during
a particular time segment. A value assigned to a selection dynamically
changes according to a set of cache retention policies, where the value
can be time-dependent functions that decay based on the class of the
item, as determined by inference about the class or via a label
associated with the item.
