NE: Surrogate-Assisted Federated Neighbor Embedding for Dimensionality Reduction

Neural Information Processing Systems

Despite its broad applications in fields such as computer vision, graph learning, and natural language processing, the development of a data projection model that can be effectively used to visualize data in the context of FL is crucial yet remains heavily under-explored. Neighbor embedding (NE) is an essential technique for visualizing complex high-dimensional data, but collab-oratively learning a joint NE model is difficult.






Copilot bug allows 'AI' to read confidential Outlook emails

PCWorld

PCWorld reports on a critical Microsoft Copilot bug (CW1226324) that allows the AI to scan and summarize confidential Outlook emails, bypassing privacy protections. This vulnerability affects Microsoft 365 accounts and compromises sensitive data like contracts and medical information stored in Sent and Drafts folders. Microsoft is rolling out a fix, but the timeline remains unclear, raising significant concerns about AI reliability and data privacy protection. For all its supposed intelligence, "AI" seems to make a lot of stupid mistakes--for example, scanning and summarizing emails marked "confidential" in Microsoft Outlook.



A Practitioner's Guide to Continual Multimodal Pretraining

Neural Information Processing Systems

However, practical model deployment often operates in the gap between these two limit cases, as real-world applications demand adaptation to specific subdomains, tasks or concepts -- spread over the entire, varying life cycle of a model.
