Safeguarding AI Visions: A New Defense Against Multimodal Attacks

22.11.2025 by Ray Dalio

The architecture leverages hierarchical vector quantization-semantic and patch-level codebooks-to distill vision encoder representations into discrete tokens, bolstering multimodal robustness, and is cultivated through a two-stage training pipeline: initial codebook and projector pretraining with multi-objective loss functions while holding vision and language model parameters constant, followed by generative loss-driven language model fine-tuning.

Researchers have developed a novel architecture to bolster the safety of large AI models that process both text and images, protecting against harmful inputs and malicious manipulation.

Holding On to Qubits: A New Strategy for Stable Trapped Ion Chains

21.11.2025 by Ray Dalio

The study demonstrates that random module failures within a quantum circuit introduce logical errors whose rate is predictably patterned by both the timing of the failure and the specific module affected, with merged modules exhibiting correlated failure modes that preclude independent error analysis-a phenomenon visualized through simulations of $600$ randomly sampled chain loss events and interpolated to provide a comprehensive map of error distribution.

Researchers have developed a method to significantly reduce errors caused by ion loss in long-chain trapped ion quantum computers, paving the way for more scalable quantum systems.
