Current Topics in Accounting Research March 23, 2011 Dr. Peter R. Gillett 4 Artificial Neural Networks Inspired by analogy with human brain McCulloch-Pitts (1943) * Simple neurons compute logic functions Hebbs Learning (1949) * Learning weights for network of artificial neurons Perceptrons – Rosenblatt (1958) * Iterative weight adjustment * Converge to ‘correct’ weights if they exist Minsky & Papert (1969) showed Perceptrons can compute only linearly separable functions (e.g., not XOR) * Learning based on ‘Delta Rule’ * Precursor of ‘backpropagation’ for multilayer nets Backpropagation – Rumelhart, McClelland et al. (1986, 1988) * Provided for training weights in multilayer models * Multilayer models with non-linear activation functions can solve general problems
