Modeling for Infant Vocabulary Acquisition System using Deep Reinforcement Learning
Masaki Taguchi, Yasuhiro Minami (UEC) HCS2019-73
Abstract (in Japanese) (See Japanese page) 
(in English) We propose an infant vocabulary acquisition model that identifies psychological infant vocabulary development findings (joint attention, learning bias, and understanding intention) associated with symbol grounding using deep reinforcement learning. In deep reinforcement learning, we use DDQN and LSTM, which treats the time sequence data of long-term dependency. We use the features obtained from real objects to ground words to those objects. Simulation experiments investigated the symbol-grounding abilities of the model and the appearances of psychological findings in the process of infant word acquisition. We confirmed that our proposed model can ground words to the objects and achieved joint attention and understanding intention. We also confirmed that it acquires (by learning) noun bias, which is thought to innately exist by many psychologists. These results confirm that the multiple psychological phenomena of language acquisition can be modeled using the latest neural network.
