Cross-Modal Knowledge Distillation without Paired Data: Theoretical Foundation and Algorithm

Researchers present a novel cross-modal knowledge distillation framework that enables large teacher models trained on one data type (e.g., images) to effectively guide smaller student models trained on different modalities (e.g., text/audio) without requiring paired training data. The approach uses distributional alignment rather than sample-level matching, establishing theoretical foundations that improve efficiency in multimodal machine learning.

Grounding Text Embeddings in Stakeholder Associations

Researchers developed the Stakeholder Grounding Exercise, a method to evaluate whether text embeddings align with human expert understanding. Studies on Danish policy and US AI use cases reveal neural embeddings underperform human experts by 16-26 percentage points, with misalignment directly impacting downstream clustering tasks.

LASA: Language-Agnostic Semantic Alignment at the Semantic Bottleneck for LLM Safety

Researchers have identified a critical vulnerability in large language models where safety guardrails fail across low-resource languages despite strong performance in high-resource ones. The team proposes LASA (Language-Agnostic Semantic Alignment), a new method that anchors safety protocols at the semantic bottleneck layer, dramatically reducing attack success rates from 24.7% to 2.8% on tested models.

MultiMem: Measuring and Mitigating Memorization in Multi-Modal Contrastive Learninga

Researchers introduce MultiMem, the first metric for quantifying memorization in multi-modal contrastive learning models. The study identifies cross-modal semantic misalignment as the primary driver of memorization, with text being the dominant modality, and demonstrates that targeted augmentations can reduce harmful memorization while improving model performance.

Sample-Efficient Post-Training for LEGO Spatial-Physics Reasoning

Researchers propose PVPO, a sample-efficient reinforcement learning method that improves LLM-based LEGO assembly generation by addressing PhysHack, a failure mode where structures satisfy physical constraints but lack semantic or geometric coherence. The approach uses selective data training and couples physical feasibility with geometric rewards, achieving better structural alignment while reducing reliance on rejection sampling.
