BREAKING NEWS! 🚨 Lukas Wegmeth and Tobias Vente arrived in #Antwerp for the #DBWRS2023! They expect two exciting days full of #RecSys talks, posters and discussions.

Early christmas present for my excellent co-authors Tobias Vente Lennart Purucker and me: FP accepted at #ecir2024 titled "Revealing the Hidden Impact of Top-N Metrics on Optimization in Recommender Systems". Thanks to the ECIR2024 for accepting research with a negative result!

Arrived at Gothenburg for a one-month research exchange with Alan Said at the Department of Applied IT. Got a really nice office! Had an amazing two-day road-trip with Tobias Vente through northern Germany, Denmark and southern Sweden to get here. Picture shows our stop at the Ribe Domkirke.

It's nice to be back in Gothenburg, visiting Alan Said and celebrating the new Erasmus+ partnership between our departments Universität Siegen and Uni of Gothenburg. I'll stay for 1 week; my PhD students Tobias Vente and Lukas Wegmeth are lucky and will stay one month isg.beel.org/blog/2024/02/2…

Road trip to Schloss Dagstuhl with Tobias Vente. First time for us. Looking forward to an exciting week with everyone! #dagstuhl24211

🌱Did you know a typical 2023 deep-learning #recsys paper generated as much CO2 as a flight from Melbourne to NY (~3,300 kg)? That's 42x more than a typical paper in 2013! More details at #recsys2024: "From Clicks to Carbon." #GreenRecSys #GreenML #GreenAutoML #DeepLearning

In extreme cases, energy consumption between #recsys experiments varied by 134,000! Also, an Apple #M1 was, for some algorithms, 90% more efficient than #NVIDIA. Read more in our pre-print or at #RecSys2024 in October. isg.beel.org/blog/2024/08/2… #Apple #CO2 #GreenRecSys #GreenML

Struggling to select the best algorithm for ranking prediction on implicit feedback datasets in #recsys?🔍 In our (w/ Tobias Vente & Joeran Beel) #RecSys24 LBR paper, we tackle this challenge!📊 Our meta-model selects the best algorithm for 48.6% of datasets in a few seconds!⚡

We also wrote a paper (w/ Tobias Vente, Alan Said, Joeran Beel) on EMERS. It was accepted for presentation at the RecSoGood workshop, co-located with #RecSys2024. You can check out the pre-print on arxiv: arxiv.org/abs/2409.15060 Of course, EMERS is on Github: code.isg.beel.org/emers

Wake up, #RecSys community! It's time to consider sustainability! We (Joeran Beel Alan Said Tobias Vente Lukas Wegmeth) call for a shift to #GreenRecSys, balancing performance with reduced environmental impact.

We (Tobias Vente Lukas Wegmeth) are thrilled that 8 of our 11 submissions to #recsys2024 and workshops (#RobustRecSys #RecSoGood) were accepted for publication. Thx Alan Said, Lien Michiels and students for the joint work. isg.beel.org/blog/2024/10/0… #recsys #greenrecsys #ensembles #datasets

Did you know that a 2023 RecSys algorithm emits 42x more CO2e than a 2013 RecSys algorithm? 📈🚨 If not, don't miss our presentation: "From Clicks to Carbon: The Environmental Toll of Recommender Systems" w/ Lukas Wegmeth , Alan Said & Joeran Beel in Session 11 at #RecSys2024! 🌍🌱

Have you wondered how much CO2 your favourite recommender system emits? A interesting study entitled “Clicks to Carbon: The Environmental Toll of Recommender Systems” by Tobias Vente et al. aimed to address the issue. #recsys2024

Tobias Vente and Lukas Wegmeth, both PhD students Universität Siegen, present their work on #GreenRecSys at #recsys2024. I couldn't be prouder; they did an amazing job during a few weeks in Sweden with Alan Said.

Honored to visit Philipp Mayr & his team at GESIS @gesisorg.bsky.social to talk about Automated Recommender Systems (w/ Tobias Vente). Inspiring discussions and a great post-talk session exploring collaborations. Excited for the possibilities ahead!

Excited to announce Checky, the Submission Checklist Generator for Authors, Reviewers, and LLMs in #RecSys, #IR, #ML, #AutoML, and #NLP! Following our work Schloss Dagstuhl, it will be published at #ECIR2025. 🚀 Demo: checky.recommender-systems.com 📄 Pre-print: isg.beel.org/blog/2025/01/0…
