Abstract
The prevalence of social media has risen dramatically, making it a crucial platform for understanding public health issues, including the expression of suicidal behavior. This study explores the feasibility of utilizing Natural Language Processing (NLP) methods to detect suicidal tendencies through Twitter posts. We employed various advanced NLP models, such as Logistic Regression (LR) and Bidirectional Encoder Representations from Transformers (BERT), to analyze the linguistic patterns and semantic nuances inherent in tweets. Our approach also included a Majority Vote system and Term Frequency-Inverse Document Frequency (TF-IDF) techniques to enhance the detection accuracy. The objective was to develop an effective model capable of early identification of potential suicide risks, which could be crucial for timely intervention and support. This research not only contributes to the field of digital mental health monitoring but also offers insights into the potential of machine learning in addressing critical societal issues. The findings suggest that while current NLP models show promise, there are complexities and ethical considerations in applying these technologies for sensitive topics like suicide detection. The study underscores the need for continuous refinement of these models and highlights the importance of integrating human judgment in the final decision-making process.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
