Experience & Projects
Machine Learning Specialist
Outlier
As an Machine Learning Specialist at Outlier, I analyze and refine AI prompts to enhance model performance. My responsibilities include training AI systems, analyzing their outputs, and improving the quality of AI-generated content. I also identify and correct errors in user prompts to ensure the highest accuracy and efficiency.
Key Responsibilities:
- Analyzed and evaluated LLM outputs across reasoning, code, and prompt-based tasks to improve model performance.
- Refined and corrected AI prompts to increase clarity, reduce model errors, and ensure high-quality outputs.
- Identified patterns in model failures and edge cases, providing insights that improved overall evaluation accuracy.
- Applied a structured review method to maintain consistency across tasks and enhance alignment with project guidelines.
