PhD Opportunities
PhD Project
Quantum-enhanced Auditing of Financial Services

Applications for this PhD project have now closed

The immutability and integrity of the auditing trials can be hugely impacted by the insecurities or anomalies in the financial transactions resulting from quantum threats. The vulnerabilities that the quantum adversaries can exploit can lead to several uncertainties in the financial data, which need to be tackled to ensure the accuracy of the auditing services. Verifying financial data and transactions against quantum threats requires understanding the principles of quantum systems, particularly quantum machine learning (QML) and sampling randomness. This project focuses on the research dimension of performing QML to ensure high prediction via quantum algorithms and simultaneously build methods for verifying financial transactions.

Project Information:

    This project aims to secure financial transactions and ensure their accuracy and verification against identifiable criteria of uncertainties. Assessing the current security standards and ensuring that these can tackle the requirements of auditing trials is another direction to explore. The research will advance our understanding of cyber security using quantum methods to determine the aspects of the unpredictability of financial transactions and offer more robust methods to safeguard against quantum vulnerabilities.

    PhD Project
    Multimodal Document Understanding

    Applications for this PhD project have now closed

    Modern documents transcend mere text, often blending imagery, tables, and other modalities, demanding advanced understanding systems. This project investigates multimodal document understanding, exploring multimodal transformers for a holistic representation of document content. This project consists of three studies, aiming to make significant contributions to multimodal document understanding as well as multimodal deep neural networks.

    Project Information:

      • Multimodal Transformers for document understanding: We will rigorously assess existing multimodal transformer architectures on document understanding tasks like information retrieval, question answering, and summarisation. This analysis will identify limitations and opportunities for improvement. We will then propose extensions to incorporate modality-aware attention mechanisms, temporal reasoning for sequential elements, and knowledge-guided fusion strategies to enhance the transformer's ability to integrate diverse information.

      • New Deep Learning Architectures for document understanding: Based on the insights from study 1, we will explore deep learning paradigms beyond transformers to synergistically integrate their strengths with other architectures like convolutional neural networks for visual features or graph neural networks for relational content. We will design novel architectures that progressively build a unified representation of the document, extracting local features from individual modalities and then fusing them to capture overarching semantic relationships. We will develop mechanisms that explicitly model the interdependencies between modalities, guiding the model's focus on relevant information across different channels.

      • Rigorous Evaluation and Applications: The proposed methods will be rigorously evaluated on benchmark datasets encompassing diverse document types and tasks. Metrics will include retrieval accuracy, question answering F1 scores, and summarisation quality. We will explore the practicality of the developed models in real-world scenarios, such as automatic document indexing, knowledge base construction from multimodal documents, and intelligent document search engines.

      CAST PhD Project
      AI Driven Digital Workers (DW) for Business Services

      Applications for this PhD project have now closed

      A digital worker is an automated piece of software designed and developed to perform parts of some traditionally defined job role. After years of development, machine automation has reached a point that enables digital workers to free humans from some repetitive and labour intensive work. This allows the human to focus more on the value-added part, and this has been shown to increase productivity and user satisfaction. More recently, deep learning applied to digital working has been shown to achieve human level performance and even outperform humans in a number of popular and simple tasks. This state of the art research motivates the development and deployment of digital workers based on deep neural networks (DNNs) within the business supply chain of some professional services. Replacing human work with robotic/automata work raises significant ethical issues and these will studied as part of the project.

      Project Information:

        The main specific aim of this project is to deliver a transparent, fair, understandable and accountable digital worker driven by deep learning.

        DNNs are increasingly used in place of traditionally engineered software in many areas. This project will explore the most promising approaches for the development of a digital worker to perform professional business support services that have a high degree of reliability. However, DNNs are complex non-linear functions with algorithmically generated (and not engineered) coefficients, and therefore are effectively “black boxes”. Hence, in this project, we are not simply developing DNNs for digital worker tasks but also carrying out quantitative evaluation against stringent metrics to evaluate the performance of specific tasks (to be identified as part of the project.)

        The project will also seek to identify a rationale for why a digital worker DNN performs in a particular manner so that stakeholders may understand and appropriately trust the work done by a digital worker.

        Once the broad stroke of the capabilities of a DNN based DW have been proved (against statistical benchmarks) the ethics of deploying such a technology will be explored so as to provide evidence for or against its use, or when or when not to use it, for example in providing a backup service when the equivalent human service may be unavailable.

        The key technological objective is:

        • To develop a DNN for performing a defined digital worker task using benchmark case studies.

        The key ethical objectives are:

        • To generate evidence for explaining the digital worker DNN and any result from the worker.
        • To examine the effects of deployment of DW are full or partial replacements for human workers.

        Secure Multimodal Virtual Reality for Remote Management of Corporate Systems and Compliance Processes

        Applications for this PhD project have now closed

        Virtual and augmented reality (VR and AR) are rapidly maturing technologies that, as yet, have not yet delivered their full potential as a comprehensive, immersive and multi-modal interactive communications medium. Nor has VR/AR been extensively deployed as an interface to embed the human in a naturally symbiotic relationship with a vast body of digital data represented in multiple forms: text, images, video, audio. We know skill acquisition is essential for human development in order to attain high levels of competency in a professional capacity. As such, the demand for accessible and optimised learning and training systems is high. 

        Project Information:

          VR and AR demonstrate the potential to improve learning practices under certain conditions by introducing features such as haptics, enhanced visual information, and intelligent tutoring, that combine for a unique and dynamic pedagogical tool. With the advent of VR and AR, virtual systems could offer ubiquitous, effective, and affordable solutions to both learn and manage corporate systems and compliance processes. Virtual systems could one day be ubiquitous, and it will be important to observe the extent to which participants are learning for personalisation and optimisation within business process applications.

          This project is required to build the necessary hardware and software to enable the collaborative and virtual presences required by systems such as those envisaged above, using a multi sensorial VR approach. The project also requires the development and examination of example scenarios. This requires the development of metrics against which to measure the effectiveness of such systems in the context of the example scenarios using techniques that provide quantitative assessment that are statistically rigorous.

          There is a developing corpus of literature dedicated to EEG analysis techniques for human-machine systems, yet applications specifically for decision-making contexts are currently limited. Data is typically acquired directly from the human component of the system via the EEG headset, which is analysed. For example, the P300 signal is frequently used in medical science and neuroscience applications, but its potential for assisting in analysing learning and memory in a training, learning and decision-making context is promising. The relationship between the P300 and working memory suggests that the signal could be a valuable metric for detecting retention in virtual training systems, but there is little research in these applied environments evaluating the suitability for this purpose.

          We propose using appropriate qualitative and quantitative analysis, including the analysis of appropriate user memory signals, to prove the VR, AR and AI can be combined to enhance the decision-making process within a business process.

          PhD Project
          Deontic Information Extraction from Regulatory Documents

          Applications for this PhD project have now closed

          This PhD project will investigate deontic information extraction from regulatory documents using deep learning and natural language processing techniques. Computer assisted regulatory compliance testing requires extraction of duty and obligation information from regulatory documents. This information extraction task is challenging since it requires identification and representation of special type of information from the regulatory document. Advances in artificial intelligence, especially natural language processing and deep learning and knowledge engineering, have the potential to make this information extraction process automatic. Existing studies have demonstrated the possibility, but there are still milestones to be achieved in this aspiration.

          Project Information:

            In this project we will investigate a deep learning centred approach to deontic information extraction. We will design a deep learning architecture, drawing on the state of the art in deep learning and deontic information extraction, which can learn a deontic information model. The deontic information model can then extract deontic information from regulatory documents.

            Objectives:

            • Investigate deontic information modelling using deep learning
            • Investigate deontic information extraction
            • Conduct a case study using regulatory documents

            PhD Project
            Risk Assessment in Synchronous and Asynchronous Complex Business Networks

            Applications for this PhD project have now closed

            This project is expected to explore operable business processes over a complex network covering multiple data sources. Depending on the type of data, the complexity of the porting software, and the dependencies between the data, these sources of data may have synchronous, asynchronous, or both characteristics. The business networks make decisions based on these inputs and are susceptible to error due to the data's multiple interconnections. As a result of the associated complexities and interdependence of the data points, several risky decision-making factors are frequently overlooked when a model of operations is so intricate.

            In a broader sense, failure to identify risk can result in inputs remaining undiagnosed for a longer period, leading to significant and more pervasive deficiencies over time. Thus, it is desired to develop methods to comprehend these entanglements of data from multiple sources in synchronous or asynchronous business networks and to provide solutions to flag the potential risks. In addition, reducing false positives without compromising the accuracy of risk mapping is an additional challenge that must be addressed as part of this project.

            Project Information:

            Business networks with multiple data points are challenging to map and profile for risks. This project is anticipated to investigate executable business processes over a complex network containing various synchronous and asynchronous data sources. The project will expand the understanding of the risk landscape and generate valid methods that can replace the existing clause approaches with more comprehensive and novel AI-assisted methods that can dynamically adjust the criteria without affecting the system's accuracy. The project will explore business processes and networks from multiple directions – link analysis, relationships between data and suspicious workflow, security risks, to name a few. Such provisioning will ensure that business decisions are taken based on true data by considering potential risks associated with the processes.

            The project aims to develop methods of defining checks and clauses with the assistance of computational game theory to reduce the false positives in the risk flagging system and introduce potential reasoning capabilities within the mappings for synchronous and asynchronous business networks that support coordinated decision-making.

            Developing and Analysing Document Understanding and NLP Systems in the Context of Business Information Extraction

            Applications for this PhD project have now closed

            The automation of repetitive information processing tasks has the potential to realise enormous advances in productivity and user satisfaction across a range of business services and solutions. Deep learning approaches, using large scale neural network models, have recently been successfully applied to many information processing tasks, including knowledge discovery and information extraction, text summarization, and text generation. Such methods have been used to generate powerful models in the legal and commercial domain; for example, state-of-the-art Natural Language Processing models have been applied to the analysis and summarization of legal documents (Elwany et al 2019), legal textual entailment (Rosa et al 2021; Yoshioka et al 2021) and modelling the structure of commercial contracts (Hegel et al 2021). Moreover, document image understanding models have shown promising utility in extracting relevant information from structured commercial documents.

            Project Information:

            In this project, the goal is to build on recent progress in deep learning and natural language processing to develop methods and systems for processing information in commercial document data and using the resultant representations to generate useful, task-relevant knowledge, for example, through text summarization, text generation, and question answering. The project will build on modern foundational models and architectures in machine learning, and in particular transformer models, such as BERT (Devlin et al 2019) and RoBERTa (Liu et al 2019). Particular problems that are to be tackled within the business services domain include defining Service-Level Agreements (SLAs), a stage in the finalisation of a contract between a service provider and a client. They are defined at different levels and used by organisations internally as well as in the supplier/customer relationship. All SLA use terminology and commonality of vocabulary that ensures the same quality of service across different units in an organisation as well as across multiple locations and subcontract work. Because of their ubiquity and importance in business services, it is costly, in terms of staff time, to ensure verification and compliance. 

            A key challenge in this project is to develop models that process textual data in a way which is transparent, understandable and accountable. The large-scale transformer models that are now ubiquitous in Natural Language Processing research are essentially “black boxes”, where the representations of linguistic meaning and the basis for output decisions by the model are not readily explainable to an end user. Currently, therefore, there is intensive research on developing a wide range of statistical methods and other analysis techniques to better quantify and explain such models (Rogers et al 2020). 

            In addition to the development of deep learning architectures and model explainability methods, an additional component of this project is to develop an assessment metric for the implemented intelligent systems and benchmark them against current practices. In particular, this will involve evaluating error rates and making recommendations for the depth of deployment of intelligent agents in practice.

            Question Answering for Testing in Industrial Contexts

            Applications for this PhD project have now closed

            This PhD project will investigate automatic question/answer generation from text using deep learning techniques, and the use of question answering for testing in education and/or industrial contexts. Question answering is part of how we learn. We learn by asking questions and searching for correct answers, and by explaining the correct and incorrect answers. Question answering is also an important means of testing learning attainment. Teachers set questions and students answer them to evidence attainment. Question answering is also an important means of testing compliance with regulations (rules and laws) in industry. Employees are often asked to complete courses about regulations and to evidence compliance by completing some tests. In either of these cases, we typically need to set questions and their correct answers manually, which is time consuming; furthermore, question answering is done by humans.

            Project Information:

            In this PhD project, we will build on existing work on question-answer generation and natural language processing in the School to go a big step further – generating questions and their answers (e.g., in the form of question-answer pairs) from text automatically, and performing automatic testing based on user submitted documents. We will also evaluate through a case study in an industrial context. Generating high-quality question-answer pairs is a key part of this project and provides the basis for automatic testing. In general question-answer pair generation will improve the performance of question answering systems, help acquire knowledge from text, and promote machine reading comprehension.

            Objectives:

            • Investigate automatic question-answer pair generation based on deep learning and knowledge graph
            • Investigate automatic testing based on question-answer pairs and user submitted documents
            • Conduct a case study in an industrial context.
