Abstract
An estimation device constructs a first estimation model and a second estimation model. The first estimation model estimates missing data within first table data on the basis of the first table data including first data indicating attributes of each user of a first user group. The second estimation model estimates missing data of a common user group within second table data on the basis of the first data with respect to the common user group in the second table data and the first table data. The estimation device estimates a value of the second data for the first user group excluding the common user group on the basis of the first estimation model and the second estimation model.
Claims6
An estimation device comprising:
- a first learning unit configured to construct a first estimation model for estimating missing data within first table data based on the first table data including first data indicating attributes of each user of a first user group;
- a second learning unit configured to construct a second estimation model for estimating missing data of a common user group within second table data based on the second table data having second data indicating attributes of each user of a second user group having partially the same common user group as the first user group and the first data for the common user group in the first table data;
- and
- an estimation unit configured to estimate a value of the second data for the first user group excluding the common user group based on the first estimation model and the second estimation model.
An estimation device comprising:
- a first learning unit configured to construct a first estimation model for estimating missing data within first table data based on the first table data including first data indicating attributes of each user of a first user group;
- and
- a second learning unit configured to construct a second estimation model for estimating missing data of a common user group within second table data based on the second table data having second data indicating attributes of each user of a second user group having partially the same common user group as the first user group and the first data for the common user group in the first table data in which the missing data is complemented by the first estimation model.
