Business Cases

  • Decoding analysis of brain activity data - R&D

    Decoding analysis was performed to estimate the task being performed by the subject from electroencephalogram (EEG) data and functional magnetic resonance imaging (fMRI) data, which measure human brain activity.

    A person's actions, thoughts, and stimuli to the five senses are always affecting brain activities. The decoding technique which uses machine learning technologies, has been attracting attention as a method to decipher a person's state from the data recorded in this brain activity.

    In this case, we used machine learning to learn the relationship between EEG and fMRI data, which record brain activity during task execution, and the corresponding task. Using the learning results, we implemented a program to estimate the type of task from brain activity and performed decoding analysis.

    EEGLAB, VBMEG, and SPM, which are standard tools, were used to analyze brain activity. The Python library scikit-learn was used for machine learning.

  • Observer evaluation support software using item response theory - development

    We developed an observational assessment support software that can take into account the rater's level of severity by using item response theory.
    Severity refers to the strength of the rater's tendency to rate the performance strictly (or leniently).

    This software consists of an evaluation tool and a management tool.

    Assessment tools are software used to assess a subject, which takes into account the severity of the evaluator's own severity and allows for a common scale that is independent of the evaluator.

    Management tools can create evaluation tools with parameters tuned to take into account the severity of the evaluator, using a statistical model that takes severity into account. It can also quantitatively determine whether each evaluator is able to evaluate from the same perspective as the other evaluators. Using the results of this analysis, licences can be issued to give access to the evaluation tool to evaluators whose evaluations meet the criteria for quality.
