LLM function calling

TextFunction Calling
As part of my work with LLM Function Calling at Turing, I have worked as an AI Trainer specializing in helping models generate structured outputs using APIs. This required me to review and analyze model outputs, assist the model in understanding the user's input, and ensure that the correct function call is generated. I have also been involved in ensuring that prompts are structured in a way that generates structured output and verifying that the output matches the intended schema.

Behavioral data architecture and strategy

TextPrompt Response Writing SFT
Reveloas AI Trainer is an instance where I participated in a behavioral data architecture and strategy project, where I had to design and improve ways through which AI can better understand user behaviors. This work entailed crafting and improving on follow-up prompts for tasks – up to ten per task, in order to improve the quality of data collected, as well as enhance consistency and provide more context. The prompts created were aimed at replicating real-life interactions in order to allow the model to learn various behavioral patterns.

PR writer

TextPrompt Response Writing SFT
As the PR Writer in Reveloas AI Trainer's PR Writer job position, I was part of a task where we had to select genuine problems(issue) found in GitHub and train an AI tool in the cloude to solve such problems in the best way possible. As part of my duties in each task I created and developed 4–6 prompts that would make the AI understand the problem and the intended result. By doing so, I managed to increase the level of logic and communication in the AI's answers.

Audio Transcribe

AudioSegmentation
Audio transcription AI training at CrowdGen entailed the process of transcribing spoken audio into structured and well-written text, taking care of issues such as noise and overlap. This was achieved by splitting the audio content into smaller segments, taking care of overlap and noises that may interfere with clear and contextually correct transcription. Other tasks included identification of speakers, use of punctuations, and editing of the transcribed content.
