Apps, wearables and machine learning for the COVID-19 pandemic

Since the beginning of the pandemic in March 2020, work at the Institute of Biomedical Engineering in the University of Oxford and at Sensyne Health, a Clinical AI company on the Oxford Science Park, has focused on improving outcomes for patients infected by the SARS-CoV-2 virus, or for individuals at risk because of possible infection by the virus. This has included the use of a remote monitoring app for pregnant women with high blood pressure and at risk of pre-eclampsia, to eliminate the need for them to attend hospital clinics fortnightly for blood pressure monitoring. In the hospital, continuous vital-sign monitoring using wearables has enabled the identification of the rapid desaturation caused by the SARS-CoV-2 virus, and intervention with corrective treatment at the earliest opportunity (e.g. via additional oxygen therapy). Use of the system decreases the amount of contact between the patient and nursing staff, reducing the risk of COVID-19 transmission. Finally, the reliability of lateral flow tests to detect infection in asymptomatic individuals has been improved by the design of an app to record the test result by taking a photo of the device and using machine learning algorithms for the automatic classification of the result.

The Transformational Journey and Future of Surgical Robotics

The use of surgical robotics has seen tremendous growth over the last 20 years and now plays an important role in the field of surgery.   These systems allow more procedures to be performed using minimally invasive techniques and improve outcomes over open surgery by reducing trauma and shortening recovery times for patients.  The exciting reality is that this is just the beginning of the transformational power of this technology.  The future of this field lies in the combination of robotics with advanced visualization, navigation, and data analytics.  This presentation will give an overview of Medtronic’s new Hugo Surgical Robotic System and discuss how it is a platform for growth in these areas to integrate new technology and enable advanced procedures.  The presentation will also explore ways that industry and academia can better partner to realize the full potential of surgical robotics by leveraging our strengths and working together.

Blockchain for Transactive Energy Management in Renewable Energy Systems

This presentation offers a vision and analyzes a scheme developed for microgrids that utilizes blockchain technologies to optimize transactive operations in power distribution systems. Technological and socioeconomic developments in distributed energy resources have promoted the use of renewable energy in microgrids as a promising alternative to the traditional use of thermal energy for electricity delivery in a bulk power grid. Microgrids are small-scale self-controllable power systems that interconnect on-site generation resources and loads for striking a local balance of energy production and consumption. Geographically-close microgrids are networked to broaden the merits of microgrids and eventually refine electricity service provisions across the power distribution system. Transactive energy, as the cross-section of technological, political and economic innovations, opens up the door to peer-to-peer autonomous electricity retail markets together with new business and operation models for power generation, delivery, and consumption. Through active participation in the decentralized transactive energy management process, networked microgrids collectively provide additional opportunities for improving the operational performance of power distribution systems. As networked microgrids are intrinsically cyber-physical systems that may unintentionally expose cybersecurity vulnerabilities to potential disruptive agents, blockchain is considered as an option that provides a transformative solution to address the cybersecurity and mutual-trust concerns through the application of cryptography and the execution of smart contracts. Accordingly, networked microgrids will interact in an automatic, credible and auditable manner for maintaining a greater degree of efficiency, reliability, resilience, and sustainability in electricity services offered to local communities. We present several practical examples and conclude that blockchain technologies embedded in transactive energy will play a significant role in the evolution of traditional power distribution systems to active and smart distribution networks.

The Enabling Technologies for Exploration of Space Missions

 

For space, technology carries a specific meaning: the means to enable exciting new missions. We have achieved many new capabilities by leveraging technologies that have seen rapid advances for mission applications. For example, the advances in hi-speed rad-hard processors is enabling autonomous spacecraft missions. Future ground-breaking discoveries, as well as NASA’s role in that future, will depend on autonomous systems, that use sensing, perception, reasoning, and decision-making, with little to no human intervention. The advantages of rapid 3D printing have been pushed to an additional fourth “dimension,” namely by constructing space systems whose functions evolve over the course of the mission. The use of the smart materials has now made it possible to develop gears that no longer require lubrication and will perform in extreme environment for a long time. Other examples include miniaturization of instruments and systems now flying in JPL’s planetary CubeSats, new robotic systems that can crawl on a wall, and the swarms of thousands of tiny autonomous spacecraft, as well as flying a helicopter in Mars atmosphere. This presentation will provide an overview of the emerging space missions and the breakthrough technologies that will enable these missions over the next two decades with emphasis on challenges in operation of autonomous systems.

Machine Learning for Decision Support in Complex Environments

This talk will present how machine learning can innovatively and effectively learn from data to support data-driven decision-making in uncertain and dynamic situations. Fuzzy Transfer Learning theories, methodologies and algorithms will be presented that can transfer knowledge learnt from one or more source domains to target domains. Knowledge transfer is achieved by building latent spaces, fuzzy mapping functions and self-training to overcome tremendous uncertainties in data, learning processes and decision outputs (classification and regression). This talk will also present Concept Drift theories, methodologies and algorithms to show how drift learning can handle ever-changing dynamic data stream environments with unpredictable stream pattern drifts through developing effective and accurate detection and adaptation methods. These new developments enable machine learning to enhance data-driven prediction and decision support systems in uncertain and dynamic environments

Ensemble Approaches to Class Imbalance Learning

Many real world classification problems have highly imbalanced and skew data distributions. In fault
diagnosis and condition monitoring for example, there are ample data for the normal class, yet data for faults are always very limited and costly to obtain. It is often a challenge to increase the performance of a classifier on the minority classes without sacrificing the performance on the majority classes. This talk discusses some of the techniques and algorithms that have been developed for class imbalance learning, especially through ensemble learning. First, the motivations behind ensemble learning are introduced and the importance of diversity highlighted. Second, some of the challenges of multi-class imbalance learning and potential solutions are presented. What might have worked well for the binary case do not work for multiple classes anymore, especially when the number of classes increases. Third, online class imbalance learning will be discussed, which can be seen as a combination of online learning and class imbalance learning. Online class imbalance learning poses new research challenges that still have not been well understood., let alone solved, especially for imbalanced data streams with concept drift. Fourth, the natural fit of multi-objective learning to class imbalance learning is pointed out. The relationship between multi-objective learning and ensemble learning will be discussed. Finally, future research directions will be given.
