Data Science Week 2023 – "Federated Learning with Analytical Workbench"

Data Science Week 2023 – "Federated Learning with Analytical Workbench" 28.04.2023

This year, I-WUNDER is once again holding its event for data analysis, algorithms and intelligent data-driven systems – the "Data Science Week 2023"!

Already for the 5th time, the Data Science Week will take place and will be something special this year after 3 years of Corona-related cancellation. From 2 – 5 May, the I-WUNDER team will meet in Gersfeld in the Rhön region and develop new innovative solutions. The theme of the week this year is: "Federated Learning with Analytical Workbench".

Federated learning is a form of machine learning in which several users or devices train local machine learning models in parallel. These models are transferred to a server, which combines all models without having access to the actual data of the clients. This creates a more robust and powerful model, which the server returns to the clients and which is optimised with each subsequent learning cycle. A major advantage of the method is data protection – the data of the individual devices do not have to be merged in an elaborate way, but only remain locally with the client. Powerful models can also be developed with small amounts of data – each client benefits from the data of the others. In addition, federated learning is expected to improve the predictive quality of the overall model.

The development week with hackathon will try out Federated Learning with different ML algorithms and explore the following questions: How well does Federated Learning work? What are the challenges in implementing the algorithm in a practical application? How fast does the method learn? Where else can it be applied?

In this year's Data Science Week, we are using a use case and image data from medicine (breast cancer detection, Wisconsin dataset), there are further use cases in autonomous driving, in online personalisation in mobile communications and the internet, in industry for predictive maintenance, in fraud detection in finance, and, and, and....

For the developments, we use the Analytical Workbench – our own analytical platform – and simulate a practical project with it.

We are looking forward to an exciting development week!

Dr Katrin Reininger lets data speak – a lecture on data visua­li­sa­tion 24.06.2021

If you can't see the meaning for all the data, it's time to find the right visualisation – that brings out the essence of your collected data, sums up all the important insights and delivers your message to the audience in an emotional and entertaining way.
Our consultant Dr Katrin Reininger is excited to give another lecture on occasion of the International School on "Programmable Smart Sensors based on Bio-compatible Nanocomposite Materials (NanoSENS)" organised by the TU Chemnitz: on 24.06.2021.

This time her message is: "Let your data speak – Using visualisations to support data storytelling". So, have your data in mind and get inspired, and discuss how to present it best in your research paper or project pitch – in front of your professor or a start-up committee. Because good visualisations can inspire and the best visualisations are those that everyone understands intuitively.
The school is online, open, and as always free of charge for students from all universities – so take the chance and join in and let your data speak!

Everybody likes projects that achieve all milestones within the given resources and everybody knows how difficult it is. A lot can be achieved with good planning, stringent coordination and a level head in demanding situations.

Project management is our day-to-day business. Hence, we are happy that our consultant and project manager Dr Katrin Reininger is giving a lecture on "Achieving your Project Goals – An Introduction to Project Management" on 02.06.2021 at the International School on "Sensors for Body Area Networks (BASNet)" organised by the TU Chemnitz:
The school is online, open, and free of charge for students of all universities – so take the chance and join!
