Center node: "Orthogonal incremental learning of a feedforward network"
  Abstract: Orthogonal incremental learning (OIL) is a new approach of incremental training for a feedforward network with a single hidden layer. OIL is based on the idea to describe the output weights (but not the hidden nodes) as a set of orthogonal basis functions. Hidden nodes are treated as the orthogonal representation of the network in the output weights domain. We proved that a separate training of hidden nodes does not conflict with previously optimized nodes and is described by a special relationship orthogonal backpropagation (OBP) rule. An advantage of OIL over existing algorithms is extremely fast learning. This approach can be also easily extended to build-up incrementally an arbitrary function as a linear composition of adjustable functions which are not necessarily orthogonal. OIL has been tested on `two-spirals' and `Net Talk' benchmark problems.
