Constructive algorithms for structure learning in feedforward neural networks for regression problems
Tin-Yau Kwok, Dit‐Yan Yeung · IEEE Transactions on Neural Networks · 1997
In this survey paper, we review the constructive algorithms for structure learning in feedforward neural networks for regression problems. The basic idea is to start with a small network, then add hidden units and weights incrementally until a satisfactory solution is found. By formulating the whole problem as a state-space search, we first describe the general issues in constructive algorithms, with special emphasis on the search strategy. A taxonomy, based on the differences in the state transition mapping, the training algorithm, and the network architecture, is then presented.
