Can brain scans lead to better AI?

Jianfeng Feng

Pioneering work by Professor Jianfeng Feng, which has recently featured in the national press, uses MRI scans to understand how the brain works and could be used to create better AI (Artificial Intelligence) systems in the future. Professor Jianfeng has discovered that the more variable a brain is, and the more its different parts frequently connect with each other, the higher a person's IQ and creativity are.

Professor Jianfeng Feng, from the Computer Science Department at Warwick, comments that

Human intelligence is a widely and hotly debated topic and only recently have advanced brain imaging techniques, such as those used in our current study, given us the opportunity to gain sufficient insights to resolve this and inform developments in artificial intelligence, as well as help establish the basis for understanding the diagnosis of debilitating human mental disorders such as schizophrenia and depression

University contributing to new advances in cancer diagnosis

Dr Nasir Rajpoot

A University of Warwick computer scientist is working with technology that could revolutionise how some cancers are diagnosed.

A high-tech computer system is able to read samples of human tissue and aid pathologists in the identification of minute changes in cells that can indicate cancer is present. More than 10,000 slides were examined in the first phase of the study[1] which shows that pathologists are as good at accurately diagnosing cancer on a computer as they are with a microscope.

Now Professor Nasir Rajpoot is working with University Hospitals Coventry and Warwickshire NHS Trust (UHCW) to develop the next generation of image analytics to use with this technology.

The ground breaking technology has the power to help pathologists grade some types of tumours, including lung, prostate and bladder tumours with precision. In prostate cancer, for example, this could make the difference between someone being offered surgery rather than drug based treatments.

The computer system known as The Omnyx® Precision Solution™, can help pathologists to see the small differences in cells in the same way that they have currently been using a microscope, allowing them to make sound decisions on many aspects of cancer diagnosis.

UHCW is the first in the UK to introduce this kind of innovation to its routine practice, meaning it is already benefitting patients.

The Omnyx system digitises slides which are traditionally placed on a microscope so that pathologists can look at them on a computer. Once on the computer, the UHCW scientists have written programmes which will separate normal from abnormal samples.

Consultant pathologist David Snead said:

“I am delighted that University Hospital, Coventry has led this ground breaking study. This provides even greater evidence that digital pathology really works, and works well. The introduction of digital pathology has fantastic potential benefits for patients. We can expect to be able to read samples more quickly than before, and the big advantage is that we can use the computer to easily manipulate an image or its data. For some patients, this additional information may change how their disease is managed.”

Mamar Gelaye, CEO of Omnyx noted:

“Dr Snead and his team have made a significant contribution to showing the value of digital pathology for both clinicians and patients. We are only at the beginning of harnessing the benefits of digitising pathology services, and we look forward to working with institutions like University Hospitals Coventry and Warwickshire NHS Trust to achieve even greater progress in delivering more accurate and efficient cancer diagnoses.”

Dr Rajpoot said:

“This is a very exciting development in the field of digital pathology. What it means is that we can now move forward with the application of digital pathology image analysis algorithms in a clinical setting. For instance, computer algorithms can automate the process of detecting normal samples so that some routine cases will not need to be looked at by a pathologist at all.

“Together with the team at UHCW, we are looking forward to developing technologies for computer-assisted diagnosis and image analytics for discovering biologically meaningful and clinically relevant signatures of cancer.”

Warwick to research how we prepare for autonomous vehicles

Dr Nathan Griffiths

  • Investigating how to manage the transition to autonomous vehicles
  • Researchers to ask how machine and human intelligence can be combined
  • Jaguar Land Rover and EPSRC fund £2m University of Warwick research

The problems surrounding the introduction of autonomous vehicles on public roads are to be addressed by new research led by the University of Warwick.

Despite progress in recent years the researchers argue that there are many unsolved challenges, not least related to how such cars will be accepted by the public.

Led by Dr Nathan Griffiths, a Royal Society Industry Fellow in the University of Warwick’s Department of Computer Science, who says that:

“The move to autonomous vehicles is most significant transition in motoring for a century, involving the complex tasks inherent to driving becoming increasingly performed by machine. Individual drivers and their cars will form part of wider and smarter urban transport infrastructure, and the cars of the future will need to be both intelligent and cooperative”.

Dr Griffiths and his co-researchers will investigate:

  • How to combine machine and human intelligence to optimise driving
  • How to manage the traffic environment through the use of big data
  • How to coordinate and control autonomous vehicles on public roads

The opportunities to deliver better safety, traffic efficiency, and more productive and pleasant journeys are enormous, but an automotive revolution on this scale faces great challenges for science and society, argue the Warwick researchers.

There has been little prior research on how autonomous vehicles will fit in with today's manually driven cars, how drivers and occupants will interact with them and how they will run safely in our towns, with pedestrians and cyclists.

The research project began following the launch of strategic partnership between Jaguar Land Rover and the EPSRC, who issued a joint call for research proposals that focussed on developing fully autonomous cars: Towards Autonomy - Smart and Connected Control. Dr Griffiths’ project is one of five selected and Jaguar Land Rover will be leading the collaboration with these successful research groups.

IBM and University of Warwick develop Big Data ethics course

Data Centre

The University of Warwick and IBM will offer researchers guidance through the ethical minefield of using big data and real time analytics.

Emma Uprichard associate professor at the University’s Centre for Interdisciplinary Methodologies (CIM), and co-director of the Warwick Q-Step Centre said:

“Researchers are increasingly turning to online tools with little or no ethical guidance other than some vague semblance that it is important to bear in mind basic key principles. Therefore, thanks to IBM, we will be developing online materials that can be used to develop and deliver successful training sessions in this area.”

Money has been granted by the IBM Faculty Awards which is a competitive worldwide programme intended to foster collaboration between researchers at leading universities worldwide and those in IBM research, development and services organisations.

The three day module will be offered to postgraduate students across CIM, Warwick Business School, computer science, Politics and International Studies (PAIS), and sociology as well as other students from a variety of disciplines that are increasingly using big data. Currently researchers gain 'informed consent' and provide assurances concerning privacy, confidentiality and anonymity when using data for studies. However as there is a diverse range of public and interlinked data available online that can be easily ‘scraped’ and ‘mined’ the ethical situation has become more complex.

Dr Uprichard will be working with colleagues Dr Maria Liakata, computer science, and Dr Arne Strauss, Warwick Business School, to develop the three day workshop on ethics of big data and data linkage. The training will be based on a similar module built and delivered by IBM at the University’s Warwick Business School. Work conducted by IBM into big data ethics will be used to shape the course content.

Professor Christina Hughes, the University of Warwick’s pro-vice-chancellor (teaching and learning) said:

“What have we done here at Warwick is demonstrate how important it is that we invest in this big data for the future of social science and for the future of the UK's contribution internationally to cutting edge – and importantly, ethical - data research and teaching more generally.”
