Vaibhavi Singh I am a graduate student in Computer Science at NYU Courant, specializing in agentic reasoning and representation learning. I research complex reasoning and autonomous planning in language models to enable robust, general-purpose intelligence. Prior to NYU, I engineered large-scale software systems at Adobe and Salesforce, building the core libraries that power Creative Cloud and Einstein AI for millions of users. Most recently, I developed production NLP systems and clinical risk prediction models in healthcare. |

Dissecting Reasoning Failures in Multimodal Chain-of-Thought
Chain-of-Thought Reasoning, Evaluation Frameworks, Vision-Language Models
Engineered the evaluation harness to audit the faithfulness of reasoning traces in Vision-Language Models. Developed a granular failure taxonomy to disentangle perception hallucinations from deductive logic errors, analyzing how models hallucinate reasoning paths even on correct answers.

Scaling Laws for Representation Learning
Scaling Laws, Data-Efficient Learning, Foundation Models, Tokenization
Conducted an empirical analysis on the limits of self-supervised learning in low-resource regimes. Analyzed the trade-off between tokenization density and dataset scale, finding that domain-aligned tokenization serves as a stronger supervision signal than sheer data volume for specialized distributions.
