Development of Active-learning dialogue data-based AI technology

Release Digest

Learning process

Hitachi today announced the development of active-learning dialogue-data based AI technology to enable EMIEW3, Hitachi's human symbiotic service robot, to spontaneously "learn" how to respond to questions that it could not previously answer. EMIEW3 clarifies the meaning of enquiries with related staff through dialogue interaction, and in the process, automatically increases its dialogue contents to increase "comprehension" for appropriate responses. Hitachi is currently developing EMIEW3 with view to use in customer service and guidance settings.

Using this technology, EMIEW3's dialogue contents can be enhanced by staff without specialist training, simply by responding to queries posed by EMIEW3, and was found to reduce labor-hours for this process to about one-tenth the time previously needed.
