| Research Abstract |
The aim of this year's study was to provide a foundation for transforming a mufti-layered perceptron with a back propagation learning algorithm which realizes an accusative/ergative case system into a neural neywork which adopts a Hebbian learning algorithm as used in our brain. Specifically, er presented and wrote a paper which examined the computational capabilities of a quantum neural network (see Matsumoto, Okubo, and Nishino 2004). This work investigated whether it is possible to apply a very powerful computational capability of a quantum neural network to neuroidal network which is is designed to simulate the process of language acquisition.
We were not able to simulate a post-'Verb Island' phase on a neuroidal network, but we are in the process of investigating how to simulate the process of acquiring an accusative linking system as found in English and Japanese under the assumption that syntactic categories such as NP, VP, or AP are innate. Specifically, we are planning to construct a neuroidal network which acquires an accusative system of grammatical relations on the basis of a bundle of semantic features as proposed by Dowry's (1995) and Ackerman and Moore's (2003) protorole theory.
Finally, we examined how the human brain comprehends an active/passive sentence, using the functional brain imaging with a particular focus on how Japanese understands (see Yokoyama., Uchida, Nakamura, Kawashima, and others 2004). a Japanese or English sentence.
