The platform is able to adapt to each individual users performance, proficiency, progress, and learning style. The technique is an efficient memorisation system that knows every word you’ve seen, how often you’ve seen it, and how long it will take for you to forget the word so it can calculate when the word should be presented to you again in a new challenge. This system was the first that Duolingo incorporated into its application. It will predict user performance, identify areas for improvement, and optimise the selection of content brought to its users. NLP within the application will structure sentences for translation, grade responses to challenges, and identify user errors.ĭuolingo incorporates ML models into the application to enhance the efficiency and effectiveness of its courses.


NLP underpins everything Duolingo does, using the techniques to generate and analyse content.
