  • A Network Embeddings based Recommendation Model with multi-factor consideration
Adrin Jalali

I'm a computer scientist / bioinformatician who has turned to be a core developer of scikit-learn and fairlearn, and work as a Machine Learning Engineer at Hugging Face. I'm also an organizer of PyData Berlin.

These days I mostly focus on aspects of machine learning and tools which help with creating more ethical and fair decision making systems. This trend has influenced me to work on fairlearn, and to work on aspects of scikit-learn which would help tools such as fairlearn to work more fluently with the package; and at Hugging Face, my focus is to enable the community of these libraries to be able to share their models more easily and be more open about their work.

  • Applying machine learning capabilities to wearable IoT devices for boxing technique management
Antonis Christofides

I've been writing software for more than 30 years. I’ve written software to streamline the management of hydro/meteorological measurements; to make time series visualization and processing easy; to provide irrigation advice; and much more. I have been working with automatic meteorological stations since 1992; I’ve occasionally written programs to interface directly with meteorological loggers; I’ve dug out dusty old handwritten weather observations and keyed them in myself; I have created various web sites and web-accessible databases; I’ve administrated servers, including email and network, and high-availability databases with automatic failover. I have written the book on Django deployment (https://djangodeployment.com).

In research, I’ve worked on water-related decision making when there are conflicting objectives; on evaluation of climate models; on causation and determinism in hydrology and the climate; and more. My opinion on climate change is that there is no evidence that it is man-made.

I help scientists and engineers create software. In particular, I help them bring their models to the web.

Leonardo Giordani

Born in 1977 together with Star Wars, bash, Apple ][, Dire Straits, The Silmarillion, and many other great things.

I started coding in April 1987 on a Sinclair ZX Spectrum. I then moved to MS-DOS PCs and in 1996 I started using Linux and became interested in operating system internals. I love software architectures, algorithms, mathematics and cryptography.

I’m mainly interested in open source software. I like both the theoretical and practical aspects of computer science.

I am currently working as a contractor DevOps and Python developer while I design a DevOps bootcamp that I will run in London from October 2022.

From 2013 I blog some technical thoughts at http://thedigitalcatonline.com.

In 2018 I published the free book “Clean Architectures in Python” http://bit.ly/getpycabook

Lilian studied Computer Science at high school and did her PhD in Computer Modelling. She went on to looking at computer applications and programming in the pharmaceutical sector before entering formal teaching for the next generation. She is currently engaged in teaching Python programming, C# and Javascript. She has given lectures in conferences both in the UK and abroad about the teaching of Computer Programming to young people. She has ran computer clubs including that of 'computer-assisted' investment for children and is a full member of the British Computer Society.

Lilian firmly believes that in this emergent brave new world, the Anthrpocene age, the computer (with its associated technologies) is the harbinger to transform globally man's short slavish existence to a better one - a world community defined by longer, richer and freer life experiences. She believes it is imperative that our schools empower our young children with his new knowledge, and Lilian herself did help reshape the Computer Science Department of an independent boys' school as Head of Department. She has produced for children more than 75 YouTube (online) videos on Computer Science and Programming - and has had more than 12,000 hits globally.
