Technological advances opened new possibilities for computing environments including smart phones, smart appliances, and drones. Engineers try to make these devices smart, self-sustaining through usage of machine learning techniques. However, most of the mobile environments have limited resources like memory, computing power and battery, and consequently traditional machine learning algorithms which require relatively high resources might not be suitable for them. Therefore, efficient versions of traditional machine learning algorithms receives interest for these kinds of environments. Recently, an operator named the ef-operator, which avoids multiplication is proposed as an alternative to classic vector multiplication. Recent studies, showed that ef-operator can be used on machine learning problems with small degradation on performance to gain energy efficiency. This thesis concerns with the application of this ef-operator over artificial neural networks. An artificial neural network architecture based of this ef-operator proposed which can approximate any Lebesgue integrable function. Applicability of standard backpropagation algorithm for this new network architecture is analyzed and a modified version of backpropagation algorithm with a line search step proposed for training this network architecture.

The passion of human-being to invent intelligent systems becomes more and more meaningful day by day, as the data captured every second by artificial sensors needs to be examined and classified for many applications. The processing of ever-increasing amount of data by defining information explicitly seems nearly impossible, regarding the variability and the amount of the information, which reveals the need for intelligent systems that are capable of learning. Deep learning is a set of algorithms that attemp...
