The weights associated with output connections are, however, re-estimated after a new hiddenunit is recruited. The functional form used for each rule is a feedforward neural network with a single hiddenunit with restricted inputs. One particular hiddenunit of their network, hiddenunit 8, was discovered to adopt three distinct levels or states of activation. One hiddenunit was recruited by each network in both conditions. Figure 2 outlines how hiddenunit representations change over training in this study. From the complex set, hiddenunit vectors were collected for the object assembly, simple language, and complex language training patterns. Once a new hiddenunit has been added to the network, its input-side weights are frozen. An average vector was calculated for each of these five sets of hiddenunit vectors. This amounts to replacing the two weights that affect the input directly (linear and bias), plus the weight on the corresponding hiddenunit. French developed a third type of semidistributed network, using an algorithm that sought to "sharpen" hiddenunit activations during learning. Networks' function approximations in each developmental stage are obtained by deriving network predictions just before a new hiddenunit is recruited. If a separation of function or specialization has occurred, we would expect to see this reflected in the pattern of hiddenunit activations of these networks at the two stages. Distinct developmental stages in learning are defined by the topological changes that occur in the network when a hiddenunit is added. The values are then ranked, so that for each word the other words that have the most similar hidden unit representation are ranked closer than those that are not. If one were dealing with just one network, the obvious approach would be to carry out a cluster analysis of the hiddenunit activations associated with each pattern set. Hiddenunit vectors (50 elements in length) were collected from the simple set for the object assembly and simple language training patterns. This ensures that each hiddenunit never forgets its original purpose, even though it may eventually play a new role in learning to solve current problems. For each new hiddenunit, the algorithm tries to maximize the magnitude of the correlation between the new unit's output and the residual error signal of the net. Many of the early techniques in reducing representational overlap involved making either the input vectors or the hiddenunit activation patterns orthogonal to one another.
