  • Publication number: 20240037456
    Abstract: In a kernel learning apparatus, a data preprocessing circuitry preprocesses and represents each data example as a collection of feature representations that need to be interpreted. An explicit feature mapping circuit designs a kernel function with an explicit feature map to embed the feature representations of data into a nonlinear feature space and to produce the explicit feature map for the designed kernel function to train a predictive model. A convex problem formulating circuitry formulates a non-convex problem for training the predictive model into a convex optimization problem based on the explicit feature map. An optimal solution solving circuitry solves the convex optimization problem to obtain a globally optimal solution for training an interpretable predictive model.

  • Publication number: 20230409994
    Abstract: The calculation means 82 calculates an accumulated material number by accumulating the number of materials in time series from a predetermined point in the past, and calculates the available number of materials by subtracting a cumulative production capacity accumulated up to an immediately preceding unit period among cumulative production capacities, each of which is a value obtained by accumulating a production capacity in each unit period in time series from the accumulated material number. Then, the calculation means 82 determines the smaller one of the number of products that can be produced, which is calculated based on the process capability, and the number of products that can be produced, which is calculated based on the available number of materials, as the production capacity, and accumulates the production capacities in time series from a predetermined point in the past to calculate the cumulative production capacity for each unit period.
