Dr. Philip Weber, MSc (Distinction) BSc (Hons). OrcID 0000-0002-3121-9625
I am a Lecturer in Computer Science at at Aston University and a research fellow at the Forensic Speech Science Laboratory and the Forensic Data Science Laboratory. With a background in systems analysis, design and administration in industry, I now focus on machine learning and AI, with specialism in both Automatic Speech and Speaker Recognition, and Business Process Mining.
Until 2019 I worked for the excellent Think Beyond Data programme, also at Aston, offering free consultancy in data analytics and machine learning to SMEs in the Greater Birmingham, Black Country and Marches areas of the UK West Midlands. Please get in touch if you could benefit from this.
I previously worked at the University of Birmingham on the EPSRC Automated Conflict Resolution in Clinical Pathways project, and before that in Automatic Speech Recognition. The outcomes of these can be found on my publications page.
My Ph.D. research studied Business Process Mining from a machine learning perspective and culminated in my thesis “A framework for the analysis and comparison of Process Mining algorithms” (2014). Please see my publications page for more information. I studied at the School of Computer Science, University of Birmingham under the supervision of Dr. Behzad Bordbar and Dr. Peter Tiňo.
Modelling Medical Care Flows
In the MitCon project we applied formal modelling (extensions to BPMN and Coloured Petri Nets) and verification techniques drawn from fields such as automated software engineering and business process modelling (Z3 and Alloy), to improve the application of medical care flows and guidelines to the treatment of patients with multi-morbidity.
Our aim in the SRbS project was to develop new ‘parsimonious’ models of speech, useful for speech recognition, inspired by human speech production and perception. At the root of this lies a seeming disconnect: recent progress in speech recognition has been achieved largely through statistical models with hundreds of thousands of parameters and vast speech corpora; whereas speech is produced by the human vocal tract which is (relatively) low-dimensional. I currently work on a Continuous-State Hidden Markov Model recogniser, and methods to automatically derive low-dimensional representations of speech.
