What it concerns

To provide a program for generating a learned model capable of relatively highly accurately estimating an intention of a subject based on brain waves of the subject, manufacturing method, manufacturing device, and connection method.SOLUTION: Each of a plurality of teacher data used for generating a learned model for estimating an intention of a subject includes information relating to brain waves and is used for machine learning after consideration of at least a part of a plurality of parameters. A program causes a computer to execute the steps of: generating a plurality of learned models by executing machine learning on each of a plurality of combinations of the plurality of parameters; calculating sensitivity and specificity of each of the plurality of learned models; and displaying a plurality of mosaic graphs on a common screen. Each of the plurality of mosaic graphs represents information relating to sensitivity in at least a part of the plurality of combinations. Regarding the plurality of mosaics, degrees of specificity, the premise, are different from one another.SELECTED DRAWING: Figure 1

Protection themes

  • Decoding

    Neural decoding

What the filing appears to be about, read by published rules from its title, abstract and classification codes. The claims define what a patent protects, and they are not read here.

Why it matters

Decoding
This is the step that turns brain activity into a command or a word. Its accuracy and speed are what a user experiences. The problem behind it: accuracy that holds over months without frequent recalibration, for more than one user and one task.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

The family

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
