Blog post about our LoRA.rar approach (ICCV'25 paper) is now online!
21 Oct 2025
[Tech Blog] LoRA.rar uses a hypernetwork to merge content and style LoRAs in real-time, outperforming ZipLoRA in speed and quality. Trained on diverse pairs, it generalizes to unseen combinations, making it perfect for edge devices.

I'll be at #ICLR2025 next week to present VL-ICL, our benchmark for multimodal in-context learning.
Find me at the poster session and happy to chat about all kinds of stuffs on multimodal LLMs and more. DM/email is welcome!

Our benchmark for evaluating in-context learning of multimodal LLMs has been accepted to ICLR'25! 🎉 Check out the project page for more details: ys-zong.github.io/VL-ICL/ 📄
23 Jan 2025
Our VL-ICL bench is accepted to @iclr_conf! It's been almost a year since we developed it yet state-of-the-art VLMs still struggle on learning in-context. Great to work with @OBohdal and @tmh31.

Looking to reduce memorization WHILE improving image quality in diffusion models?
Delighted to share our work "𝐌𝐞𝐦𝐂𝐨𝐧𝐭𝐫𝐨𝐥" now accepted at WACV '25 (@wacv_official). We show strong results for medical image generation and also establish an initial benchmark!

Career update: I'm excited to share the news that I've recently joined Samsung Research! 🎉
I'll be primarily doing research on large language models.
Looking forward to catching up with friends in London 🇬🇧 🙌 and also meeting new people here!

VLGuard is accepted to #ICML2024! Check out our strong baseline for 🛡️safeguarding🛡️ VLLMs: ys-zong.github.io/VLGuard/
6 Feb 2024
Your #VLLMs are capable, but they are not safe enough! We present the first safety fine-tuning dataset VLGuard for VLLMs. By fine-tuning on it, the safety of VLLMs can be substantially improved while maintaining helpfulness. Check here for more details: ys-zong.github.io/VLGuard/

Noise can be helpful for improving generalisation and uncertainty calibration of neural networks - but how to use it effectively in different scenarios? Find out in our recent paper that was accepted to #TMLR!
3 Apr 2024
I am thrilled to share our latest paper, "Navigating Noise: A Study of How Noise Influences Generalisation and Calibration of Neural Networks openreview.net/forum?id=zn3f…," published in @TmlrOrg, This work is a collective effort by @OBohdal , @tmh31, @mrd_rodrigues and myself :).
