🎉 Wrapping up an incredible 2.5 days of non-stop excitement at #ACSFall2023 ! 🚀
Can you believe it? We rocked:
👥 47 demos with our awesome visitors
🔮1512 model predictions
🧠 2 model retraining
And yes, we might've unintentionally set a world record for trashed coffee ☕ 1/3 – at San Francisco, CA

Our paper “Unifying Molecular and Textual Representations via Multi-task Language Modelling” got accepted at #ICML2023🎉🎉. This work presents Text+Chem T5, a multidomain/multitask LM for both the chemical and natural language domains. Try it out now: ibm.biz/textchemt5
A team work featuring: @georgosgeorgos @JannisBorn @OleWinther1 @teodorolaino and @drugilsberg @IBMResearch @DTU
Link to the preprint: arxiv.org/pdf/2301.12586.pdf
The model is also already available via the #GT4SD python library.

Easter egg🥚in @NatMachIntell: Regression Transformers! Sounds contradicting? Not to us!
➡️ SOTA performance in (bio)chemical regression tasks w/o regression heads. Pure MLM!
The best: RT is dichotomous & also excels at conditional molecular generation🧵ibm.biz/rtnmi23

New feature in #paperscraper (0.2.4), our package for paper keyword searches & scraping publication metadata.
Now you can download PDFs, either for individual papers or for scraped metadata dumps 🚀🎉
Install via pip. Code: ibm.biz/paperscraper
Thx for suggestions @skepteis
A super interesting week in Baltimore attending @icmlconf is coming to an end. Yesterday, I had the pleasure to present our Patent Generative Transformer (PGT) model during the KRLM workshop. A Language Model able to understand patents and facilitate the patent drafting process.
Do you want to speed up your patent application drafting or just curious about the model? You can access the model via hf’s hub ibm.biz/pgt_model or use it directly from the #GT4SD python library (including our suggested postprocessing steps) ibm.biz/gt4sd-pgt-notebook
For more information, you can have a look at the preprint ibm.biz/BdPivy, or feel free to reach us!
