The method for checking the linear separability of a given set of binary training patterns in a binary supervised learning of an artificial neural network is also proposed in the thesis. If the training patterns are linearly separable, then it can be implemented by the perceptron. And there are some applications of the improved learning algorithm in later chapters.

In this thesis, the improved supervised binary learning model of ANNs and some applications will be proposed. The supervised and unsupervised learning algorithms are two kinds of learning algorithms distinguished by learning methods. And the learning data could be separated to binary and continuous data.
Perceptron is the earliest applicable method of supervised binary learning model, yet it solved only the linearly separable problem. Linearly nonseparable problems have been resolved by backpropagation learning algorithm using hidden units. The convergence of backpropagation was proved, but the learning maybe fail. Therefore, we proposed the improved learning structure and algorithm, which could learn successfully, based on functional link units.
However, the algorithm requires much more storage for functional link units, resulting much more computation time. It is well known that if the given set of binary training patterns is linearly separable, then successful learning can be achieved using only perceptrons without any functional link unit. Consequently, to reduce the number of functional-link cells required for successful learning, it is crucial to provide an easy method for checking the linear separability of each set of binary patterns of the input training example. The method for checking the linear separability of a given set of binary training patterns in a binary supervised learning of an artificial neural network is also proposed in the thesis. If the training patterns are linearly separable, then it can be implemented by the perceptron. And there are some applications of the improved learning algorithm in later chapters.
