Professor Colunga's research concerns several areas of language learning in very young children. For the DREU program, I am specifically looking into recommender systems - such as those used by companies like Netflix and Amazon - and the potential to use the same algorithms to determine words that children will likely learn next, based on what they already know. We hope to be able to use these techniques with the application through which parents of participating children enter information about their children's current vocabularies, and recommend words that the children might know.
