1. A method of location determination performed by an electronic device including a transceiver and a memory storing an AI model, the method comprising:
receiving, via the transceiver, a first fingerprint associated with a first person and a first environment, wherein the first person is an unregistered user;
obtaining, based on the first fingerprint, a first set of feature data;
determining, based on the first set of feature data, a reconstruction loss associated with the first person and the first fingerprint;
in case of the reconstruction loss being less than or equal to a threshold:
classifying, based on the first set of feature data, the first fingerprint to obtain a first estimated location label of the first person, and
outputting, an indicator of the first estimated location label of the first person;
in case of the reconstruction loss being greater than the threshold, performing a registration of the first person.
