It has been submitted in partial fulfilment of a degree in Master of Science in Data Science at the University of Stavanger. The work herein is entirely my own.  \nAbstract  \nQuantum machine learning combines the realms of quantum computing with artificial intelligence, providing novel approaches to problem-solving. Quantum image recognition is one such problem that has attracted significant attention. However, many existing algorithms face a common challenge – current quantum hardware has limited available qubits. Based on the quantum machine learning framework anointed quantum feed-forward neural network, this thesis proposes novel data encodings for image recognition. By fully leveraging the capabilities of quantum computing, these new encodings represent more of each pixel’s information without requiring additional qubits. Specifically, the encodings are devised to characterise continuous pixel values, three-channel binary pixel values and three-channel continuous pixel values. In particular, the three-channel encodings enable the model to consider colours in images for increased performance. Through extensive evaluation of various datasets, the proposed encodings are demonstrated to enhance the performance of the quantum feed-forward neural network. Furthermore, the model is extended to the multi-class problem, further showcasing the improvement which the encodings provide. The work done herein is exploratory by nature, tested through classical simulations of quantum computers. As many quantum image recognition models utilise many of the same principles as the quantum feed-forward neural network, it is reasonable to imagine that the ideas and insight present in this thesis can be applied to such other models.  \nAcknowledgements  \nI would like to express my thanks to my friends and family for the help and support writing this thesis, both through constructive conversations and proofreading. Furthermore, I would like to thank my supervisor Shakut Ali and his colleagues for providing me with the idea and opportunity to work on this cool project.  \nContents  \nPreface iii  \nAbstract iv  \nAcknowledgements v  \nList of Figures ix  \nList of Tables xi  \nList of Algorithms xiii  \n1 Introduction 1  \n1.1 Introducing quantum computing . . . . . . . . . . . . . . . . . . . . . . . 1  \n1.2 Quantum computing in machine learning .................. 2  \n1.3 Quantum image recognition .......................... 2  \n1.4 Research objectives . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3  \n1.5 Contributions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4  \n1.6 Structure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5  \n2 Background 7  \n2.1 Image representation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7  \n2.2 Datasets . . .","cbCaitjbptZjb33i","https://ap.wps.com/l/cbCaitjbptZjb33i","pdf",1750030,1,95,"English","en",105,"# Introduction\n## Research objectives\n## Contributions\n# Background\n## Image representation\n## Datasets\n## Quantum computing\n## Quantum machine learning\n## Image classification in QML\n## Gradient descent optimisers\n# Methods\n## Quantum Feed-Forward Neural Network\n## Data encoding\n## Image representations\n## Pixel dataset\n## Tetrominoes","[{\"question\":\"What problem does the thesis address in quantum image recognition?\",\"answer\":\"Many quantum image recognition methods are limited by the small number of qubits available on current quantum hardware.
