1. A system for facilitating creation of a new radiation treatment plan, the system comprising: a database of previously planned radiation treatment plans of other patients for radiation treatment; memory that stores computer-executable instructions; and at least one processor configured to execute the computer-executable instructions, which, when executed, cause the at least one processor to provide: a feature extractor configured to receive at least one feature associated with patient data of a patient who is to receive radiation treatment for creation of the new radiation treatment plan for the patient; a prediction component configured to predict, based on the at least one feature associated with patient data, at least one metric correlated to treatment dose, wherein the prediction component has learned using previously planned radiation treatment plans to predict the metric based on features extracted from patient data of patients associated with previously planned radiation treatment plans; a search component configured to search the database and identify, based on the at least one predicted metric correlated to treatment dose, at least one radiation treatment plan from the database of previously planned radiation treatment plans, the at least one radiation treatment plan identified as having a match to the at least one predicted metric; and a user interface configured to present, to a user, the at least one identified radiation treatment plan or one or more parameters associated with the at least one identified radiation treatment plan as a recommendation for creation of the new radiation treatment plan.
