Artificial intelligence apparatus and method for estimating sound source localization thereof

A method for estimating a sound source localization of an artificial intelligence apparatus, the method comprising:

• receiving input sensor information related to a target object via the input sensor;
• obtaining object data from the input sensor information;
• grouping the object data to generate a grouped data set corresponding to the target object;
• obtaining a first estimate of a position of the target object based on the object data;
• acquiring identification information of at least one external device positioned around the target object at the first estimated position;
• receiving additional input sensor information related to the target object from the at least one external device positioned around the target object and extract additional object data from the additional input sensor information;
• grouping the additional object data in the grouped data set corresponding to the target object;
• and
• obtaining at least one additional estimate of the position of the target object based on the additional object data,
• the method further comprising:
• generating test data set comprising at least one of the object data or the additional object data;
• inputting the test data into a pre-trained artificial intelligence model to estimate a sound source localization and provide a sound source localization estimation result information including a position, action, and moving direction of the target object;
• calculating a sound source localization estimation evaluation score of the artificial intelligence model for the test data;
• classifying the test data into validation data based on the calculated sound source localization estimation evaluation score;
• retraining the artificial intelligence model based on the validation data;
• and
• inputting the test data into the retrained artificial intelligence model to update the artificial intelligence model.
