Claim 9:
10. A non-transitory machine readable medium having stored thereon processor-executable instructions that when executed cause performance of operations, the operations comprising:
generating user trails of activities performed by users;
generating a vocabulary based upon mappings of activity descriptions to indices, wherein the indices are mapped to a set of activities identified from the activities as having frequencies above a threshold, wherein the mappings comprise (i) a first mapping of a first activity description to a first index assigned to a first activity having a first frequency above the threshold and (ii) a second mapping of a second activity description to a second index assigned to a second activity having a second frequency above the threshold;
training a model using the user trails, timestamps of the activities, and the vocabulary to learn a set of time-preserving embeddings; and
utilizing the set of time-preserving embeddings to perform a first task.
