Some queries on "Comments on 'Approximation capability in C(R~/sup n/) by multilayer feedforward networks and related problems'"

In the comments letter by Huang et al. (ibid. vol.9 (1998)) the authors claimed that the boundedness of a sigmoidal function /spl sigma/(x) is neither sufficient nor necessary condition for the validity of the approximation theorem discussed in our original paper (ibid. vol.6 (1995)). In this paper, we show that this claim is incorrect.
