Abstract: A method and system of interactive tutoring is provided. A question is sent to a user device. Upon determining that the response does not correspond to a known correct answer, a concept map is identified and a cost function between the correct answer and the response is determined. Upon determining that the cost function between the correct answer and the response is above a predetermined threshold, the question is identified to be the origin. Otherwise, the response is identified to be the origin. A present academic proficiency of the student is determined. A difficulty boundary based on the academic proficiency of the student is determined. A next question is provided between the origin and the correct answer, based on the determined difficulty boundary of the student.

Abstract: Systems, methods, and computer program products to perform an operation comprising receiving text input via a chat interface of a tutor application, identifying, by at least one classifier applied to the text input, a concept in the text input, mapping the concept in the text input to at least one of a visual action and a first visual object, generating, based on a first machine learning (ML) model, a first program code statement corresponding to the at least one of the visual action and the first visual object, and executing the first program code statement to modify a visualization interface of the tutor application based on the text input received via the chat interface.

Abstract: Method and apparatus for generating natural language observations using sequence-to-sequence models are provided. The method includes receiving a first electronic document and dynamically generating, without requiring user intervention, a first natural language observation corresponding to a first portion of the first electronic document by processing the first portion of the first electronic document using a first sequence-to-sequence model. A second natural language observation is received for the first portion of the first electronic document, and the generated first natural language observation and the authoritative natural language observation are provided. The method further includes receiving an evaluation of the first natural language observation and the second natural language observation, and refining the first sequence-to-sequence model based on the evaluation of the first natural language observation and second natural language observation.
