New blog post experimenting with using semantic search to find potential machine learning models for fine-tuning on the Hugging Face model hub. danielvanstrien.xyz/huggingface/huβ¦



I'm super happy to share that I have joined Google research this fall as a PhD research intern in California to work on multilingual search w/ Daniel Cer, Jianmo Ni! ππ₯³ It's my first time in the US. If you are in the bay area, let's meet! πΊπΈπ» #google #internship #NLP #IR


Activation functions reduce the topological complexity of data. Best AF may be diff for diff models and diff layers, but most Transformer models use GELU. What if the model learns optimized activation functions during training? led by Haishuo with Ji Ung Lee and Iryna Gurevych


I am super proud to share the work of my Google AI internship π FiD-Light is an efficient retrieval-augmented generation model advancing the state-of-the-art effectiveness on six KILT tasks considerably π w/ Jiecao Chen Karthik Raman Hamed Zamani π arxiv.org/abs/2209.14290



New paper π¨ arxiv.org/abs/2211.09260 Can we train a single search system that satisfies our diverse information needs? We present ππΈβπ π₯§ the first multi-task instruction-following retriever trained on πΉπΌββπ π«, a collections of 40 retrieval tasks with instructions! 1/N


Happy to collaborate with Yongxin Huang . Congrats!
