{"url":"/dataset/mmdb","name":"MMDB","full_name":"Multimodal Dyadic Behavior","description_markdown":"Multimodal Dyadic Behavior (MMDB) dataset is a unique collection of multimodal (video, audio, and physiological) recordings of the social and communicative behavior of toddlers. The MMDB contains 160 sessions of 3-5 minute semi-structured play interaction between a trained adult examiner and a child between the age of 15 and 30 months. The MMDB dataset supports a novel problem domain for activity recognition, which consists of the decoding of dyadic social interactions between adults and children in a developmental context.\r\n\r\nSource: [MMDB](http://cbs.ic.gatech.edu/mmdb/)","description_withheld":null,"homepage":"http://cbs.ic.gatech.edu/mmdb/","introduced_date":"2013-06-01","introduced_date_note":null,"introduced_by":{"paper":"/paper/decoding-childrens-social-behavior","title":"Decoding Children's Social Behavior","first_author":"J.
