4 MARS – Séminaire DIC-ISC-CRIA

Combining unsupervised and supervised grounding approaches

Par Oliver Roesler

Résumé :
There exist a variety of grounding approaches that either utilize supervised or unsupervised learning techniques to ground words through corresponding percepts. Supervised approaches are usually sample efficient but depend on the availability and trustworthiness of a tutor, while unsupervised approaches avoid this dependency, yet, they are less sample efficient and often also less accurate. So far, only limited work has been done to combine both approaches. In this talk, I will present recent work on combining cross-situational learning and interactive learning approaches to enable artificial language learners to benefit from the support and feedback of another agent, e.g., a human, without depending on it.
