Bridging the Gap: Adapting Generative Models with Rotational Alignment

December 28, 2025 by BBG News

Direct alignment methods falter when faced with rotational variance, whereas a self-rotated alignment strategy-by internally accounting for these transformations-demonstrates a resilience to misalignment, suggesting an inherent adaptability absent in naive approaches.

A new approach leverages feature space rotation to enable generative models to quickly adapt to new datasets with limited examples.

The Serpent in the System: How Attackers Are Quietly Spreading Through Industrial Networks

December 28, 2025 by BBG News

An attacker can compromise a Programmable Logic Controller (PLC) designated as PLC 3 by strategically traversing through multiple intermediary PLCs, effectively using them as stepping stones to reach the target.

New research reveals a stealthy technique for lateral movement in Operational Technology environments, allowing attackers to navigate between Programmable Logic Controllers without triggering traditional security alerts.

Bridging the Belief Gap: Decentralized Planning for Multi-Agent Teams

December 28, 2025 by BBG News

In a collaborative fire detection scenario, agents operating with incomplete and unshared information exhibit predictably inconsistent beliefs about environmental states - illustrated by heightened uncertainty regarding unobserved cells - leading to a reciprocal movement strategy that satisfies minimal rational agent consistency (MRAC); however, when assessed within a fully observable multi-agent partially observable Markov decision process (MPOMDP), the system’s collective knowledge reveals that certain cells ([latex]C[/latex]) possess a demonstrably higher degree of uncertainty than others ([latex]A[/latex] and [latex]B[/latex]), prompting a coordinated shift in observational focus toward those critical areas.

A new approach allows teams of agents to coordinate effectively even when they have differing understandings of the world.
