Abstract

The computational requirements of operating machine learning algorithms are increasing faster than the performance improvement provided by new fabrication processes. This has lead to an increase of data centres size and, subsequently, of energy consumption and operational costs. To allow machine learning algorithms to develop further, new technologies that have been designed to increase computational efficiency are necessary. This thesis proposes to harness magnonics to develop a convolutional encoder capable of performing computations more efficiently. Such a device could then be scaled to achieve effective parallel matrix-vector multiplication computations; thus easing machine learning algorithms operations. Specifically, the magnonic convolutional neural network was designed, fabricated and tested using structured YIG thin film. The accuracy achieved in image recognition tasks are higher than 90%, which is comparable to software-based approach. These results show high potential and feasibility of magnonics as a novel technology for efficient neuromorphic processing.
