RESEARCH PROJECTS
Enhancing Reliability and Relational Understanding of Visual Language Models
This research aims to address the limitations of Visual Language Models (VLMs), including hallucinations and poor relational understanding. The project proposes benchmarks to evaluate and understand these issues, and develops improved decoding approaches to detect and prevent hallucinations during text generation, enhancing VLM reliability and accuracy.
