Hi! I am a final year PhD student at Robotics Institute of Carnegie Mellon University, advised by Prof. Deva Ramanan. I did my undergrad in Computer Science and Maths at Cornell University and served as college symbol bearer (top 5 of the college). My current research focuses on computer vision and language, especially evaluating and improving multimodal generative models.

GenAI-Bench: Evaluating and Improving Compositional Text-to-Visual Generation
Zhiqiu Lin*, Baiqi Li*, Deepak Pathak, Emily Li, Yixin Fei, Kewen Wu, Xide Xia*, Pengchuan Zhang*, Graham Neubig*, Deva Ramanan*
- We propose GenAI-Bench, a comprehensive benchmark for compositional text-to-visual generation.
- We release over 80,000 human ratings to support future evaluation of automated metrics.
Evaluating Text-to-Visual Generation with Image-to-Text Generation
Zhiqiu Lin, Deepak Pathak, Baiqi Li, Emily Li, Xide Xia, Graham Neubig, Pengchuan Zhang*, Deva Ramanan*
- We propose VQAScore, the state-of-the-art alignment metric for text-to-image/video/3D models.
- VQAScore based on our new CLIP-FlanT5 model outperforms previous metrics based on GPT-4Vision or costly human feedback.
Revisiting the Role of Language Priors in Vision-Language Models (VisualGPTScore)
Zhiqiu Lin*, Xinyue Chen*, Deepak Pathak, Pengchuan Zhang, Deva Ramanan
- We use generative VLMs to implement Visual Generative Pre-Training Score (VisualGPTScore), i.e., the probablity score of generating a text given an image.
- Such a generative score achieves top-tier image-text retrieval performance on multiple compositionality benchmarks, surpassing all discriminative approaches by a great margin.
- We further investigate the role of language prior P(text) through a probablistic lens, and introduce a debiasing solution that consistently improves the VisualGPTScore under train-test distribution shifts over text.
Language Models as Black-Box Optimizers for Vision-Language Models
Zhiqiu Lin*, Shihong Liu*, Samuel Yu*, Ryan Lee, Tiffany Ling, Deepak Pathak, Deva Ramanan
- We use ChatGPT to effectively optimize vision-language models without white-box access to model weights or gradients.
- We show successful applications in visual classification, text-to-image generation and personalization.
The Neglected Tails of Vision-Language Models
Zhiqiu Lin*, Shubham Parashar*, Tian Liu*, Xiangjue Dong, Yanan Li, Deva Ramanan, James Caverlee, Shu Kong
- Popular vision-language models (CLIP, MetaCLIP, OpenCLIP) are all long-tailed learners trained on drastically imbalanced web data, causing biases in downstream applications such as visual chatbots (GPT-4Vision) and T2I generation (Stable Diffusion, DALL-E 3).
- We fix these biases through our SOTA prompting and retrieval-augmented strategies.
Multimodality Helps Unimodality: Cross-Modal Few-Shot Learning with Multimodal Models
Zhiqiu Lin*, Samuel Yu*, Zhiyi Kuang, Deepak Pathak, Deva Ramanan
- We propose a simple cross-modal adaptation method for multimodal models that repurposes information from other modalities (e.g., class names and audio clips) as additional training samples.
- For CLIP, it achieves SOTA few-shot adaptation performance even with a simple linear probe, and consistently improves prior art such as prompting, adapter, and weight ensembling.
- Audiovisual experiments with AudioCLIP suggest that one can learn a better dog visual classifier by listening to them bark.
LECO: Continual Learning with Evolving Class Ontologies
Zhiqiu Lin, Deepak Pathak, Yu-Xiong Wang, Deva Ramanan*, Shu Kong*
Website | Arxiv | NeurIPS’22 Talk
- A practical lifelong vision benchmark motivated by real-world dataset versioning issues, e.g., Mapillary 1.2 to 2.0.
- Simple but effective solutions such as joint training, semi-supervised learning, and learning-with-partial-labels to address inconsistent annotation (both coarse-grained and fine-grained).
