Interactive Fiction & Conversational AI Analysis

TextText Generation
In this interactive fiction series project, I wrote serialized narratives with multiple branching outcomes to analyze and evaluate AI conversational performance. I embedded realistic human-like dialogue, emotional escalation, and contradictions to test advanced AI comprehension. I collaborated on performance analysis and used feedback to deepen the narrative complexity for training. • Constructed branching dialogue to simulate diverse conversational paths • Developed challenging scenarios featuring nuanced emotional cues • Assessed the naturalness and believability of AI-generated continuations • Provided dataset enhancements for red-teaming and consistency testing

Prompt Engineering Experiments for LLMs

Text
I designed targeted prompts to assess instruction-following, accuracy, and creativity of large language models. My focused input structures contributed to improved reliability and sophistication of AI-generated results. I performed iterative revisions and test runs to optimize the effectiveness of each prompt. • Engineered innovative prompts for scenario-based AI evaluation • Analyzed AI responses to identify strengths and vulnerabilities • Utilized prompt variants to test context retention and multi-step reasoning • Documented methodologies and results for reproducibility and scalability
