GENERATION APPARATUS, GENERATION METHOD, AND PROGRAM
A generation apparatus is provided for generating an output sequence from an input sequence, wherein the input sequence is a sequence of information, and the output sequence is a sequence of another piece of information. The generation apparatus includes a processor; and a memory storing instructions that cause the processor to execute a process. The process includes generating an input sequence with constraint information based on the input sequence and constraint information; generating output information by inputting the input sequence with constraint information to a sequence conversion model; and generating the output sequence by performing a constrained search using the output information such that the output sequence includes the constraint information.
