Abstract: Disclosed herein are a multi-target analysis apparatus and method. The multi-target analysis apparatus includes: an input/output interface configured to receive data and output the results of computation of the data; storage configured to store a program for performing a multi-target analysis method; and a controller provided with at least one process, and configured to analyze multiple targets received through the input/output interface by executing the program. The controller is further configured to: collect instruction-target pairs in each of which an instruction and state information for a target are matched with each other so that the target is specified through the instruction, and generate an instruction-target set having a plurality of instruction-target pairs; and train a reinforcement learning-based learning model configured to receive the instruction for the target and the state information for the target and output action information by referring to the instruction-target set.
