Thesis on neural network

This has lead to state-of-the-art performance being achieved across severalpreviously disconnectedproblem domains, including computer vision, natural language processing, reinforcement learning and generative modelling.

These success stories nearly universally go hand-in-hand with availability of immense quantities of labelled training examples "big data" exhibiting simple grid-like structure e. This is due to the extremely large number of degrees-of-freedom in neural networks, leaving their generalisation ability vulnerable to effects such as overfitting. However, there remain many domains where extensive data gathering is not always appropriate, affordable, or even feasible.

The resurgence of structure in deep neural networks

Furthermore, data is generally organised in more complicated kinds of structurewhich most existing approaches would simply discard. Examples of such tasks are abundant in the biomedical space; with e. I hypothesise that, if deep learning is to reach its full potential in such environments, we need to reconsider "hard-coded" approachesintegrating assumptions about inherent structure in the input data directly into our architectures and learning algorithms, through structural inductive biases.

Every neuron has its own internal this inner state is known as the initiation level of neuron, which is the capacity of the information sources the neuron gets. There are various activation functions that can be connected over net information, for example, Gaussian, Linear, Sigmoid and Tanh. The inputs are executed by a few weights, mixed together to offer a yield.

The feedback from the yield is again put into the contributions to manage the actualized weights and to train the system. This structure of the neural networks help to solve the practical, nonlinear, decision making problems easily. The neural system utilized as a part of our approach is perceptron neural group.

Pre-thesis Presentation Topic: Recurrent Neural Network (RNN)

The perceptron is a system that learns measures, i. This system weights and examples could be prepared to deliver a right target vector for given the relating input vector. The preparation technique utilized is known as the perceptron learning standard.

Perceptron Neural Network is picked because of its capacity to sum up from its training vectors and activation functions. Vectors from a training set are introduced to the system in a sequential manner.

Otherwise, the weights and biases have updated with the use of the perceptron. When the whole dataset has been trained like this then the training is completed. Chen, Jian-Rong Theory and applications of artificial neural networks. Doctoral thesis, Durham University.

In this thesis some fundamental theoretical problems about artificial neural networks and their application in communication and control systems are discussed. We consider the convergence properties of the Back-Propagation algorithm which is widely used for training of artificial neural networks, and two stepsize variation techniques are proposed to accelerate convergence.

Simulation results demonstrate significant improvement over conventional Back-Propagation algorithms.

We also discuss the relationship between generalization performance of artificial neural networks and their structure and representation strategy. It is shown that the structure of the network which represent a priori knowledge of the environment has a strong influence on generalization performance. A Theorem about the number of hidden units and the capacity of self-association MLP Multi-Layer Perceptron type network is also given in the thesis. In the application part of the thesis, we discuss the feasibility of using artificial neural networks for nonlinear system identification.
