Research Student
Performed research on contrastive learning for vision-language pretraining advised by Prof. Alex Dimakis.
- Adapted CLIP with synthetic Q&A augmentation and distribution-level objectives, achieving +6% accuracy gains and improving multimodal alignment and transferability.
- Extended CLIP with a BLIP-2–trained synthetic dialogue tower, using contrastive fusion to improve zero-shot retrieval while preserving its pretrained capabilities. (SSL@NeurIPS 2023)
