Reproducible symptom subtypes of depression identified using unsupervised machine learning

Quote:Clusters aligned with the existing clinical subtypes, atypical and melancholic depression, alongside other potentially novel clusters reflecting a range of different symptom profiles. Atypical clusters hypersomnia with weight gain appeared in both Q1 and Q2 and were associated with younger age and higher body mass index. Distinct clusters combining insomnia, weight gain, and having thoughts of death were associated with asthma, suggesting potential inflammatory dysregulation. Further clusters were characterised by psychomotor changes and showed strong associations with Parkinsons disease, both before and after the mental health questionnaire was conducted.

Metas Internal Tests Reveal AI Failed Child Safety Checks

Quote:Expert witness Damon McCoy, a professor at New York University, testified about Metas internal red-teaming results after reviewing documents the company provided during the discovery phase of the litigation. According to the internal report presented in court, Meta tested its chatbot product across three critical safety categories. The results showed significant failures across all three areas. In the child sexual exploitation category, the product demonstrated a failure rate of 66.8 percent. For sex-related crimes, violent crimes, and hate content, the failure rate reached 63.6 percent. Even in the suicide and self-harm category, the product failed to provide adequate protection 54.8 percent of the time.
