Towards Test-Time Refusals via Concept Negation Peiran Dong 1 Song Guo 2 Junxiao Wang 3 Bingjie Wang

Neural Information Processing Systems

Here is a breakdown of the three steps involved: 1) Prototype: We utilize CLIP to encode a collection of text prompts obtained from social media platforms that express similar negative concepts. These encoded features are then aggregated into a comprehensive prototype feature, capturing the semantics of the negative concepts.


Study of Buddhist Monks Finds Meditation Alters Brain Activity

WIRED

New research reinforces that it's a mind-altering, dynamic state that promotes focus, learning, and well-being. If you've ever considered practicing meditation, you might believe you should relax, breathe, and empty your mind of distracting thoughts. Novices tend to think of meditation as the brain at rest, but a new international study concludes that this ancient practice is quite the opposite: Meditation is a state of heightened cerebral activity that profoundly alters brain dynamics. Researchers from the University of Montreal and Italy's National Research Council recruited 12 monks of the Thai Forest Tradition at Santacittฤrฤma, a Buddhist monastery outside Rome. In a laboratory in Chieti-Pescara, scientists analyzed the brain activity of these meditation practitioners using magnetoencephalography (MEG), technology capable of recording with great precision the brain's electrical signals.

Neural Information Processing Systems

Computational social choice is a research area at the intersection of social choice (the science of collective decision-making) and computer science, which focuses on the algorithmic analysis of problems related topreference aggregation and elicitation(Brandt etal.,2013).
