Especially the panel on evaluations of RAG approaches was very insightful 👍 Excited to see GenIR evaluation getting more and more solid 🙂18 Nov 2024 21:24 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3lbau7bppes2ihttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxcckho2cActually, we already submitted some very similar approaches to TREC BioGen. Let's see how that plays out 😉13 Sep 2024 06:12 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxcckho2chttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxcgryt2sFollow-up on our #BIOASQ2024 submission: We actually submitted the best approach for some of the tasks 👍 Looking forward to further improving Medical RAG! #CLEF202412 Sep 2024 08:29 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxcgryt2shttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxfuxur2ehttps://www.theguardian.com/science/2024/feb/03/the-situation-has-become-appalling-fake-scientific-papers-push-research-credibility-to-crisis-point?CMP=Share_iOSApp_Other04 Feb 2024 18:21 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxfuxur2ehttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxfxcvb2cReminder that research that relies on OpenAI models is (usually) not reproducible.04 Jan 2024 09:47 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxfxcvb2chttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxiwmyq2v📄 Pre-print: https://webis.de/publications.html?q=argument#reimer_2023b 💾 Code: https://t.co/FKq6Yx4cto12 Oct 2023 19:44 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxiwmyq2vhttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxiyuyr24Hence, we propose better few-shot and zero-shot stance detectors based on GPT-3.5 and Flan-T5.

GPT-4 etc. are effectively black boxes and should therefore be used very carefully.25 Mar 2023 00:37 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxq37bk2nhttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxq5zot2oI don't agree. We're doing science for the public and that includes companies as well. If you don't want your models/code/ideas to be used by anyone, then write a patent instead of a paper. Or release your model weights and data under some less permissive license.25 Mar 2023 00:37 +0000at://did:plc:vmlprmshgvykihetbnd26jkb/app.bsky.feed.post/3ljgbxq5zot2ohttps://bsky.app/profile/heinrich.merker.id/post/3ljgbxtes3r24I'm very honored to be awarded the #Deutschlandstipendium from @BMBF_Bund and @LBBW at @UniHalle.
