Abstract: Some embodiments of the present invention are directed towards techniques for building and using machine learning enhanced trees for automated solution determination in a technical support context. Historical technical support records with associated problems, actions and results are received and clustered. A solution determination tree is constructed from the clustered actions, and a machine learning model is trained to predict which action will lead to a solution based on an accumulated data set including a problem and subsequent results from previous actions. Using the solution determination tree and the machine learning model, classes of actions are recommended based on accumulated data for an incoming support request/problem or a result resulting from a executing a previously recommended action.
