Tip: German Data Science Days 2024

Dear visitor!

In some of my recent newsblog articles (read those here and here) I collected 32 HR tech conferences and 13+1 HR & People Analytics Conferences.

And although this seems, with almost 50 conferences, as a collection covering many important data events, it cannot be complete of course (and I did not strive for it neither).

German Data Science Days 2024

Las friday I found another conference that might be of interest for you if you are working with data, statistics, and analytics – thus in the field of data science and in the case of HR data in HR & People Analytics (more or less HR data science, but this term is not used that often):

The German Data Science Days 2024.

The conference is dated March 7 – 8, 2024, and will take place at the Ludwig-Maximilians-Universität München (LMU Munich). It is organized by the German Data Science Society and has happened since 2018 (the society’s founding year) each year until 2023, which sums up to six conferences by now.

The 2024 conference includes topics and speakers like:

Alexander Haag, ERGO: “Navigating the fusion of AI generations in the insurance industry with ERGO’s AI Factory”

Monica Epple & Christian Pich, Swiss Re: “Navigating the future – How Swiss Re is unlocking data to drive innovation in reinsurance”

Jasmin Weimüller & Dr. Christoph Weisser, BASF: “How is BASF enabling its workforce to use generative AI & Co – Use cases and enablement” [Human Resources!]

Prof. Dr. Florian Stahl, Universität Mannheim: “The BERD data marketpace: A platform connecting companies, universities and research institutions and fostering the collaboration in research and innovation”

Michael Herter, infas 360: “Data Science für Städte und Kommunen”

Murat Topuz, Deutsche Bank: “Fighting financial crime with data analytics”

Karin Immenroth, RTL: “Mit KI in die datengetriebene Zukunft von RTL Deutschland”

Past Conferences 2018 – 2023

And if you look closely and open the pages of the past conferences form 2018 until 2023 you will not only find the programmes of these, but also the presentations (charts, slides) of almost all speakers as a PDF to download (and in one case as a Google Doc presentation).

Here are some sessions of past conferences:

Dr. Fabian Winter, Munich Re: “Data and Analytics at Munich Re” (2023)

Dr. Heide-Gesa Löhlein & Ibrahim Gökce, Telekom: “Personalization in Telecommunications: Mission Impossible?” (2023)

Christian Most, Lufthansa Group: “The Beauty of Complexity: Decision Support in Operations Steering” (2023)

Peter Mayer, Volkswagen AG: “Applying Computer Vision at Volkswagen Group IT” (2022)

Dr. Anca-Oxana Tudoran & Manuel Jockenhöfer, ProSiebenSat.1: “Data Science in the Media” (2022)

Ralph Müller-Eiselt, Bertelsmann Stiftung: „Wir und die Algorithmen – Beziehungsstatus: kompliziert” (2020)

Event New Year

Happy New Work, Vitra, Visier & BASF

Dear visitor!

Eleven days have passed in 2024 and I wish you a very happy New Year! That is still okay, since wishes for happiness are regardless of time and place anyway, right?

But as you read correctly the first words are Happy New Work, and that is more accurate for someone whose business is to improve human resource management (HRM) by People Analytics, AI, and Digital Assessment.

So I hope the first 11 days were good for you, and you started your work with excitement and energy just like me after some relaxing days off with loved ones, good food (my first duck in the oven thanks to TV cook Steffen Henssler!), and walks in the woods and at the Rhine.

And this time off was needed since I had been busy the last few months with, for example, a client report on HR software for executive search, our own new market report on People Analytics & AI with 100+ tools (coming soon), the re-design of Schorberg Analytics’ website and our new flyer. Moreover I am now also operating from Workspace Factory Campus in Düsseldorf: A unique place for inspiration, co-working, and community.

But what’s up and maybe interesting for you?

Let’s start with Vitra – the well-known design furniture company. Due to their Innovation People Lab at Zukunft Personal Europe 2023, I was invited for two special days at their headquarters in Weil am Rhein on the first two days in February: I am thrilled to join this Learning Journey “New Work” on the Vitra Campus. Perhaps you will be there too?

Those interested in People Analytics are aware of Visier: A leading HR platform in this field that started its global success 2010 in Vancouver. Next Thursday, 18 January, there will be an online session on how BASF Performance Materials has transformed HR Analytics with Visier. I am looking foward to this case study! More: https://events.visier.com/BASF

As an independent People & Digital HR Analyst there is nothing in it for me promoting this event (or the Vitra event), and you should also check out other vendors as well like ChartHop, Crunchr, Erudit AI, functionHR, HRForecast, Ingentis, Knoetic, Lanteria HR, One Model, or Orgnostic – Or turn to our People Analytics & AI market 2024 report shortly ;-).

By the way: Have you received our free PDF Big Book List on People Analytics yet? Check it out too!

Have a nice end of the week and all the best for you!

Why a pitch is a Berg-Pitch: How five Startups and Amiaz Habtu rocked the audience

Dear guest!

Yesterday evening, October 19, 2023, it was time for another Berg-Pitch – the 13th to be exact – and it was a blast! The wonderful Luisa Skrabic moderated this unique event, and the stage at codecentric AG in Solingen was filled with excitement, passion, innovation, drinks & food, and rap music!

Although it started raining on my arrival at the outstanding headquarters of the well-known IT company the warm welcome from the team of the organiser, Solingen.Business (the Wirtschaftsförderung of the city) and a cool drink before the start of the event in the nicely designed entrance hall put the guests in the right mood.

After introducing words by head mayor Tim Kurzbach, this time online, Frank Balkenhol (CEO of Solingen.Business) and a few information about the event by Luisa the stage was opened for the following five startups and their 6-minute pitches (and 6-minute Q&A-Sessions):

  • saasmetrix,
  • victorioso nutrition,
  • Repair Rebels,
  • MANSIO, and
  • Innovative Robot Delivery.

And they all did a great job: The speakers, founders, and/or CEOs, showed their passion and commitment for their various products and services in well structured presentations.

The first speaker Marcel Banmann from saasmetrix GmbH offered a tricky and complete integration for several cloud-based Tools used by employees (like Slack), while Pablo Klüppelberg and Ben Decker from victorioso nutrition UG presented a fast performance-revovery and keeping method (so called “pouches” that you put in your mouth) for top athletes in team sports such as football and basketball – with future offerings for amateur athletes and high performance jobs as well. The third presentation did Dr. Monika Hauck from Repair Rebels GmbH, which has built an online platform to connect customers with fashion and clothing repair needs (the startup’s primary focuses at this time) with local craftspeople like tailors.

After a break for drinks and talks between guests, we saw a revolutionary system from MANSIO GmbH for saving resources in the transport of goods by trucks presetented by Maik Schürmeyer – And an equally smart solution by Innovative Robot Delivery GmbH for the sending of parcels and saving on packaging brought to us by Boris Meyer.

The event was a highly professional in every way, from the organisation to the speakers to the closing with delicious wraps and a very wide range of drinks.

And that was not just it! Even though the audience was already cheered up, Amiaz Habtu topped it with his new rap songs and the start of his singing career. The moderator of the German TV start-up Show “Die Höhle der Löwen” (The Cave of the Lions) unleashed the emotions of the audience with his singing and acting, getting right into heart of the crowd.

In his keynote and interview with Luisa, Amiaz told us about his roots and the beginning of his TV career, as well as the challenges and obstacles along the way. He also involved the audience by asking and answering some questions about his new role as a musician (which surprisingly included me too, as he wanted to know if I had understood his rap lyrics; see the the link to the video of the live stream for the whole event below).

Finally it was then time to announce the winners of the Berg-Pitch Competition, as voted for by a panel of judges and participants online or via the app. It was a difficult decision, as all the candidates made a lasting impression with their fine products and services. But since only one could win, the choice was made and Repair Rebels took the 4,000 Euro prize home.

Besides all of that I also enjoyed my talks with the interesting people I met and talked to at my seat, during the break and the get-together afterwards very much. Thank you!

A big applaus to those who made this great event possible: Phil Derichs and his team from Solingen.Business, codecentric AG for their hospitality, the judges for their work, and the support of several local sponsers – interestingly with fourtexx GmbH one from the HR Tech industry. We thank all of them deeply!

And as with the Olympics, so with this special 13th edition of the Berg-Pitch: It was important to be there. We look forward to the next Berg-Pitch, but the bar is now set pretty high.

Have a good day and all the best,

Stefan Klemens

HR Data Science: Salary Prediction at Trivago and StepStone

Dear guest!

On Tuesday evening, 29th of August 2023, I was at the Düsseldorf Data Science Meetup at Trivago, the Online search company for hotels, in their extraordinary headquarters in the Medienhafen of Düsseldorf, my birth city.

I left my office in Solingen early in the afternoon that day since I met with my business friend Dominik Rühl before the event – and walked in the sun from the Düsseldorfer Landtag (state parliament) at the Rhine to our meeting point at UCI cinema near Trivago.

It was good to see Dominik after about five years – And we had a fruitful exchange on our common topics artificial intelligence (AI), recruitment, skills, and digital assessment as well as some private issues. He is now working as a HR & Recruiting Manager at Advance Business Partner GmbH based nearby in the city of Neuss on the other side of the Rhine. The consulting company focuses on mobility services in different areas like recruitment, innovation, and transformation management.

Although the summer and weather this year in Germany is pretty unstable, we enjoyed sitting outside with our drinks at unique brewery bar Eigelstein.

Find out more about the Düsseldorf Data Science Meetup Group with its interests in Data Science, Machine Learning and Python/R, on this website.

Arriving at Trivago

At 6 pm it was time to walk to nearby Trivago building, finished in 2018. The individual modern styled entrance area and the café behind offers a glimpse on how the interior of the building is decorated (see this article and this article about the New Work culture at Trivago and the architecture of the headquarter´s spaces.)

Surprisingly we, with another guest, were the first participants arriving (ok, it was half our before the official start and talks started even later), but were soon picked up by Gina from Trivago. Together we (and a cart full of pizza in yellow boxes for the data people) were lifted by one of the elevators to the top floor for the location event.

A stunning view to the south-west skyline from the roof terrace reached our eyes, and Dominik, the coming participants, and me enjoyed drinks and pizza before the event started at 7 pm.

Our co-host Aida Orujova gave us a very warm welcome, she introduced the speakers, and broke the ice by asking who is from data science, who is from engineering, and who just there to know more about salaries.

First talk: Alexander Fischer, Trivago

Alexander Fischer from Trivago started with his talk about is passion for the programming and statistics software R, and his (and the economists´) “Swiss knife” methodical approach for prediction outcome variables: Linear Regression. He showed how he and his team used this classical algorithm with packages R´s fixest, and PyFixest to predict wage by using the variables education and ability (e.g. intelligence).

In his presentation of the problem in doing that (“The error term is correlated with the dependent variable”) he referred to a recent study using data from 59,000 Swedish men published 2023 by Marc Keuschnigg, Arnout van de Rijt, and Thijs Bol in the European Sociological Review (number 20, pages 1-14), titled “The plateauing of cognitive ability among top earners” (online article published here on January 28, 2023).

Since AB-Testing (or randomized experimental and control group design) is not feasible in the model (sending randomized individuals in one group for example one year more to college) the classical solution in Social Sciences and Psychology are Quasi-Experiments which were first introduced in the literature by standard book “Quasi-Experimentation: Design and Analysis Issues for Field Settings” written by Cook and Campell (1979).

As a solution for not manipulation experimental the years of education as predictor of the wage Alexander used therefore a variable called “distance to college” as a natural differing factor between people regarding their years of education.

The data scientist from Trivago further pointed out in his “The Secret Sauce” slide that taking the role of companies into account in the corresponding regression model, the computation is quite demanding (millions of employees, thousands of companies, 20 years of data) – But he presented of course a solution for it (and that was not Spark!).

At the end with the help of programming language Python and package PyFixest Alexander showed that the prediction of salary can be done, and he answered the questions of the audience.

Second talk: Michael Matuschek & Tim Elfrink, StepStone

In the second talk this evening we learned from Michael Matuschek and Tim Elfrink how StepStone is predicting the salaries of all kinds of jobs for their salary products.

Michael begun the session, and gave an overview about StepStone´s salary products include the Salary Planer, Salary on Listings, and Auto-generated Salary SEO pages.

As a result of a 2020 study and further research before it turned out that salary is for 96 % of the respondents the most important criteria when choosing a job (flexible working ours, career & training opportunities, and corporate culture, reach only 90 % resp. 91 %).

Michael Matuschek with Tim Elfrink from StepStone answering a question from the audience. Foto. Stefan Klemens. Thanks both for their approval of the picture!

Michael told us also about the challenges in prediction salary at StepStone regarding data distribution and features (more white collar jobs and little part-time data for example) and: The gender pay gap, quality assurance, feature engineering, the underlying model and the used algorithm, as well as the metrics (main business KPIs) accuracy and generalisation.

After him Tim Elfrink took the mic and explained the broader infrastructure of the predicting IT system with AWS and the auto deployment of the model. Further subtitles of his presentation were for example: Creating scalable infrastructure and development environment.

A number of questions (and some hints for improving their model) came from the participants, and Michael and Tim were happily answering them.

Closing, socks, and outlook

At 8.30 pm presenter Aida Orujova returned to the stage again and thanked all guests and speakers for being there. As several others I took the chance to talk with some participants (see header picture), before I needed to catch my tram to travel home.

My second Düsseldorf Data Science Meetup was another wonderful experience (read about my first here), and the scheduled next event in October 2023 is of course on my list.

Oh, one last thing (we learned this from the apple guy, right?) I did not mention yet. Before the start the participants could grab one, two, or three promotional gifts from Trivago as shown in the picture: One for using your hand to write (still common among a few people I was told), one for storing big data in a small piece of metal, and one to keep your feet between 28 ° C and 33 ° C (surface temperature of the extremities as I learned writing this sentence) when external temperatures fall in later autumn.

Promotional gifts for the participants of the Düsseldorf Data Science Meetup from Trivago. Foto: Stefan Klemens

As I like to test digital and analogue things (I have high scores on openness to experience (see the Big Five Personality Traits) and curiosity which is one of my signature strengths according to the VIA-Model), the usefulness of the trivagonian socks to prevent cold toes needed to be proven also.

Note: If you like to know more about psychological traits and psychometric assessment of these for HR recruiting, selection, and development, then click on my work as a Work Psychologist as presented here: https://www.digitalassessment.de/

I can say that my feet got warmer but the real test of course – and perhaps then like a case study (N = 1) with more treatments like a stepstonian, a sipgatian, and quantopian fabric as well a control (no treatment, that is walking without socks! preparing for that right know!) – will be conducted in colder times which are coming soon to Germany. I will report on it! 😉 And perhaps you wanna join the experiment to lift the “N”, so results will be more valid?

Me testing the Trivago socks: And I am smiling realizing the double meaning of the words and symbols matching the two main areas of the company. Foto: Stefan Klemens

With this of course rather funny ending, I thank very much the organizers and speakers for this evening, and Trivago for hosting the meeting! Will we see us next time on a Düsseldorf Data Science Meetup (or another place if you like)?

Many greeting and all the best to you!
