    Strachey Lecture - How Are New Technologies Changing What We See?

    Strachey Lecture - How Are New Technologies Changing What We See?

    There has been a proliferation of technological developments in the last few years that are beginning to improve how we perceive, attend to, notice, analyse and remember events, people, data and other information. There has been a proliferation of technological developments in the last few years that are beginning to improve how we perceive, attend to, notice, analyse and remember events, people, data and other information. These include machine learning, computer vision, advanced user interfaces (e.g. augmented reality) and sensor technologies. A goal of being augmented with ever more computational capabilities is to enable us to see more and, in doing so, make more intelligent decisions. But to what extent are the new interfaces enabling us to become more super-human? What is gained and lost through our reliance on ever pervasive computational technology? In my lecture, I will cover latest developments in technological advances, such as conversational interfaces, data visualisation, and augmented reality. I will then draw upon relevant recent findings in the HCI and cognitive science literature that demonstrate how our human capabilities are being extended but also struggling to adapt to the new demands on our attention. Finally, I will show their relevance to investigating the physical and digital worlds when trying to discover or uncover new information.

    Strachey Lecture - Mixed Signals

    Strachey Lecture - Mixed Signals

    Mixed Signals: audio and wearable data analysis for health diagnostics Wearable and mobile devices are very good proxies for human behaviour. Yet, making the inference from the raw sensor data to individuals’ behaviour remains difficult. The list of challenges is very long: from collecting the right data and using the right sensor, respecting resource constraints, identifying the right analysis techniques, labelling the data, limiting privacy invasion, to dealing with heterogeneous data sources and adapting to changes in behaviour.

    Strachey Lecture: The Quest for Truth in the Information Age

    Strachey Lecture: The Quest for Truth in the Information Age

    The advantages of computing for society are tremendous. But while new technological developments emerge, we also witness a number disadvantages and unwanted side-effects. The advantages of computing for society are tremendous. But while new technological developments emerge, we also witness a number disadvantages and unwanted side-effects: from the speed with which fake news spreads to the formation of new echo-chambers and the enhancement of polarization in society. It is time to reflect upon the successes and failures of collective rationality, particularly as embodied in modern mechanisms for mass information-aggregation and information-exchange. What can the study of the social and epistemic benefits and costs, posed by various contemporary mechanisms for information exchange and belief aggregation, tell us? I will use Logic and Philosophy to shed some light on this topic. Ultimately we look for an answer to the question of how we can ensure that truth survives the information age?

    Strachey Lecture: Getting AI Agents to Interact an Collaborate with Us on Our Terms

    Strachey Lecture: Getting AI Agents to Interact an Collaborate with Us on Our Terms

    As AI technologies enter our everyday lives at an ever increasing pace, there is a greater need for AI systems to work synergistically with humans. As AI technologies enter our everyday lives at an ever increasing pace, there is a greater need for AI systems to work synergistically with humans. This requires AI systems to exhibit behavior that is explainable to humans. Synthesizing such behavior requires AI systems to reason not only with their own models of the task at hand, but also about the mental models of the human collaborators. At a minimum, AI agents need approximations of human’s task and goal models, as well as the human’s model of the AI agent’s task and goal models. The former will guide the agent to anticipate and manage the needs, desires and attention of the humans in the loop, and the latter allow it to act in ways that are interpretable to humans (by conforming to their mental models of it), and be ready to provide customized explanations when needed. Using several case-studies from our ongoing research, I will discuss how such multi-model reasoning forms the basis for explainable behavior in human-aware AI systems.

    Strachey Lecture: How Innovation Works: Serendipity, Energy and the Saving of Time

    Strachey Lecture: How Innovation Works: Serendipity, Energy and the Saving of Time

    Innovation is the main event of the modern age, the reason we experience both dramatic improvements in our living standards and unsettling changes in our society. Innovation is the main event of the modern age, the reason we experience both dramatic improvements in our living standards and unsettling changes in our society. Forget short-term symptoms like Donald Trump and Brexit, it is innovation itself that explains them and that will itself shape the 21st century for good and ill. Yet innovation remains a mysterious process, poorly understood by policy makers and businessmen, hard to summon into existence to order, yet inevitable and inexorable when it does happen.
