INFORMATION PROCESSING APPARATUS, INCENTIVE PLAN CALCULATION METHOD AND PROGRAM
An information processing apparatus includes a data acquisition unit that acquires data indicating a relationship between success or failure of a task and an amount of a loss-framed incentive indicating an incentive that is forfeited in a case where the task is not successful, and information indicating a motivation function representing motivation of a user for the task, a parameter determination unit that determines a parameter of the motivation function based on the data, and an incentive measure calculation unit that calculates an incentive measure indicating an amount of a loss-framed incentive based on the determined parameter and the motivation function.
1 . An information processing apparatus comprising:
a processor; and
a memory that includes instructions, which when executed, cause the processor to execute a method, said method including:
acquiring data indicating a relationship between success or failure of a task and an amount of a loss-framed incentive indicating an incentive that is forfeited in a case where the task is not successful, and information indicating a motivation function representing motivation of a user for the task;
determining a parameter of the motivation function based on the data; and
calculating an incentive measure indicating an amount of a loss-framed incentive, based on the determined parameter and the motivation function.
2 . The information processing apparatus according to claim 1 ,
wherein the motivation function includes a term of a loss-framed incentive presented and a term of a temporary acquisition incentive, and each term includes a power function, a sigmoid function, or a min function.
3 . The information processing apparatus according to claim 1 ,
wherein the determining includes estimating likelihood of a probability model in which the task is successful by maximum likelihood estimation and determining the parameter.
4 . The information processing apparatus according to claim 1 ,
wherein the calculating includes calculating the incentive measure by solving a Bellman optimality equation so as to maximize an expected value of a reward sum in a Markov decision process, assuming that success or failure of a task follows the Markov decision process.
5 . An incentive measure calculation method performed by an information processing apparatus, the incentive measure calculation method comprising:
acquiring data indicating a relationship between success or failure of a task and an amount of a loss-framed incentive indicating an incentive that is forfeited in a case where the task is not successful, and information indicating a motivation function representing motivation of a user for the task;
determining a parameter of the motivation function based on the data; and
calculating an incentive measure indicating an amount of a loss-framed incentive, based on the determined parameter and the motivation function.
6 . A non-transitory computer-readable medium having computer-readable instructions stored thereon which when executed cause a computer including a memory and a processor to execute the method executed by the processor in the information processing apparatus according to claim 1 .
