Medical Accelerator Data Science

  • by

Particle accelerators have a direct impact on society through several of their applications in medicine. With the advancement of accelerator science, new techniques for the treatment of cancer and diagnosis of various diseases have provided major steps forward in healthcare during the last decades. But particle accelerators are hi-tech machines with a challenging operation. In this post, we describe how Data Science solutions help automating their operation and optimizing the performance of such fascinating facilities.

Machine Learning for Medical Devices

  • by

Medical devices containing a machine learning algorithmic component, e.g. for diagnosis, have a huge market and health potential. But getting the approval to sell a medical device is possible only after a thorough process of certification. For this, the particularities of statistical learning need to be taken into account as soon as possible in the device design. Otherwise, the risk of getting trapped in the certification process with suboptimal -viability killing- components is just too high. In this post we describe good practices for machine learning development and operationalization within medical devices, driven from our experience at PickleTech.

Data Science for Emergency medicine

Data Science for Emergency Medicine

In Emergency Medicine, decisions need to be made fast, and with a limited view on the patient’s health status. While the time urgency is imperative, in Emergency Medicine not all the decision outcomes are visible immediately.  Actually, some may take quite some time to show up, turning feedback and learning processes into a challenge. Limited resources impose in addition a very severe constraint, which makes Emergency Medicine too many times a complex resource optimization problem in nature. We discuss here how Data Science has the potential to improve Emergency Medicine, focusing on some of the opportunities for such a complex context.

Data Science Cycling Echelons

The Drag Side of the Moon

At PickleTech we thrill when two -apparently- separate projects end up connected in some way. And when the reason is related to Physics, writing about it becomes an imperative. Do you know what connects a Tour de France stage with the management of a constellation of satellites?

Aerodynamic drag heavily impacts both cycling and low Earth orbit satellites. Estimating drag with precision and integrating it on complex operational strategies are key to their success. Data Science is contributing to optimize such complex challenges with the use of Artificial Intelligence and Machine Learning techniques.

Individualization matters: the gradient adjusted pace model of Kilian Jornet

Gradient Adjusted Pace (GAP) models are integrated as a common feature in many running sports devices and companion apps. Recently, Kilian Jornet announced his movement from Suunto to Coros, and one of the anecdotal quotes to motivate the change was Coros interest on Kilian’s adjusted pace model. How useful is it to look at a GAP model not derived from your own individual data?

Kilian-Coros’ example highlights the importance of individualized performance modeling for athletes. In this post, we derive the individual GAP model for Kilian. Thanks to his collaboration, we have computed the model using only his own recorded data from last year’s activities. We compare his individualized GAP version with the public version by Strava, focusing on what makes Kilian the ultimate mountain athlete.

Data Science in Space: ready for launch!

Mix Space Exploration with Artificial Intelligence and you already have the plot for a science-fiction story. But reality may not be that far away from this picture as we might think. In this post we write about actual applications of Data Science in Space: from satellite data applications to already existing solutions for satellite operations and space mission assistants.

Learnings from a Conversation with Kilian Jornet

Domain knowledge and field experience are key to creating impact through data science. For our projects, we rely on surrounding ourselves with world experts in their fields. With them we have opened our YouTube channel, to kick off with the series of interviews: Driven by Science. For the first episode, we spoke with Kilian Jornet: the ultimate mountain athlete. We discussed sports performance, mental health, technology, nature preservation, and, of course, data science. Kilian openness provided us with very interesting insights. And actually, the video triggered quite some online discussions around feeling and data in sports. We reflect on that here.

Algorithm Audit for a Trustworthy AI

  • by

The EU Ethics Guidelines for Trustworthy Artificial Intelligence emphasize that any AI system should be lawful, ethical, and robust; and that each of these components in itself is necessary but not sufficient for trustworthy AI. Not challenging your AI system in these three aspects can have unexpected consequences. It is about ethics, but it is also about competitiveness. At PickleTech we provide algorithm audits as a service, and when this is available, the responsibility to challenge AI systems should not be evaded anymore. Here we write about the key elements we focus on when working on AI system auditing.

Training for a reward

  • by

Reinforcement Learning is rapidly progressing. Every other day, new applications across domains are developed. At PickleTech we closely follow the progress of reinforcement learning techniques, researching, and being ready to apply them when beneficial for a project. We have already implemented them in the field of particle accelerators.  Last week, we were invited to give a seminar at the Physics Department at the University of Oxford to talk about it. Now, we exploit its impact in the fields of Health and Sports.

Individual performance… a team effort!

When you read constrained multi-objective optimization problem or game theory, you will most probably not think of Julian Alaphilippe or Elisa Balsamo next… or will you? Last weekend of September we travelled to Flanders to assist, first line, to one of the most exciting cycling races of the year, the 2021 UCI Road World Championship. Beyond boosting our passion for cycling even more, we had time to reflect on the present and future of data science in such an epic context.
