Break the AI models

OtherTextEvaluation RatingPrompt Response Writing SFT
This project is focused on improving the AI's accuracy by correcting its wrong answers. The primary task is to write prompts that challenge the AI's knowledge and reasoning, causing it to generate factually incorrect or logically flawed responses. Each wrong answer is then carefully evaluated to identify the specific error, and a new, verified response is written to provide a correct and trustworthy example for model training.

Data Annotation TechAudioClassificationEmotion Recognition
This project focuses on creating a comprehensive dataset for audio-based emotion recognition. The tasks include recording audio samples, classifying the primary emotion expressed (e.g., joy, anger, sadness), transcribing and translating the spoken content, and evaluating the intensity and clarity of the emotional expression. The resulting multilingual dataset is designed to train more nuanced and culturally aware AI models
