Patent attributes
A method may include extracting, from historical clickstream data, historical user events, generating historical user features from the historical user events, generating, using the historical user features, a training data set including feature vectors each labeled with an outcome of a historical requested event, adding, to a decision tree: internal nodes corresponding to the historical user features, branches corresponding to the values of the historical user features, and leaf nodes each corresponding to an outcome of the historical requested event. The method may further include extracting, from new clickstream data, new user events, generating new user features from the new user events, detecting a request to cause a new requested event, and predicting an outcome of the new requested event by traversing a path including: a series of branches each corresponding to a value of one of the new user features, and a leaf node corresponding to the outcome.
