Freelancer Overview

I have extensive experience in AI training, primarily focused on RLHF (Reinforcement Learning from Human Feedback) projects. These involved creating complex prompts to test model limitations, evaluating two AI-generated responses based on criteria such as accuracy, verbosity, prompt alignment, clarity, and writing quality, and rewriting responses to provide the most appropriate output. I provided detailed feedback reports for each evaluation. My expertise spans areas such as mathematics, chemistry, and general topics. Additionally, I have worked on projects evaluating AI-generated voices, assessing aspects like listening ease, geographic speech adaptation (EUA and Brazil), naturalness, cooperativeness, verbosity, and prompt alignment. I have also participated in image classification projects, identifying the presence or absence of humans, distinguishing between photos with human presence, artistic human representations (paintings, sculptures), or no human-related content. Lastly, I have contributed to projects that evaluated the presence or absence of videos on websites and classified these videos as either the main content of the page or supporting material.
