40 results about "Repetitive behavior" patented technology

Repetitive behaviors are characteristic of a variety of disorders or dysfunctions of brain development, such as autism spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD) or obsessive compulsive disorder (OCD).

Short sequence recommendation method based on user repeated behavior pattern mining

The invention discloses a short sequence recommendation method based on user repeated behavior pattern mining, and the method comprises the following steps: 1), carrying out the article representationlearning of a given user behavior sequence, and obtaining the feature representation of an article; 2) converting the behavior sequence of the user into a repeated behavior pattern sequence, and predicting the item selection probability of repeated behaviors: predicting the probability that each item in the sequence is re-clicked next time according to the repeated behavior pattern sequence; 3) article selection probability prediction of exploration behaviors: predicting the probability that each article which does not appear in the behavior sequence of the user is clicked in the next behavior; 4) calculating probability distribution of repeated behaviors and exploration behaviors of the user; and 5) according to the results of the steps 2) to 4), obtaining the probability that each article is clicked next time. According to the invention, the repeated behaviors of the user are modeled, and the long-distance dependency relationship in the sequence is captured, so that the accuracy ofrecommending articles to the user can be effectively improved.
