Existing methods assume shared features across data tables to enable knowledge transfer between domains, which is unrealistic in practice. \\mds{This paper introduces generalized context learning to remove the requirement of shared features across domains. The generalized context captured by transformer projection weights for $key$, $value$, and $query$ provides rule-based generalization rather than the domain-specific context conventionally learned from transformer activations. Projection weights for $key$ from the source domain interact with the weight for $query$ in the target domain to achieve Cross-domain Attention Transfer Learning (CATTLE) in a data-agnostic manner. Our experiments on ten pairs of disjoint source-target data sets show that CATTLE can learn generalized context from a single source data set and is rank-wise and statistically superior to nine state-of-the-art baselines, including machine learning, deep learning, and transfer learning methods using large-scale pre-trained models. CATTLE achieves the best average rank (2.9) and delivers a 3.7% average AUROC gain over the baseline methods.} The CATTLE source code is available at https://tinyurl.com/pr5s8ywn.", "url": "https://wpnews.pro/news/generalized-context-in-cross-attention-for-transfer-learning-of-disjoint-tabular", "canonical_source": "https://www.machinebrief.com/news/generalized-context-in-cross-attention-for-transfer-learning-nnz6", "published_at": "2026-08-31 04:00:00+00:00", "updated_at": "2026-08-31 04:52:12.389726+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["CATTLE", "arXiv"], "alternates": {"html": "https://wpnews.pro/news/generalized-context-in-cross-attention-for-transfer-learning-of-disjoint-tabular", "markdown": "https://wpnews.pro/news/generalized-context-in-cross-attention-for-transfer-learning-of-disjoint-tabular.md", "text": "https://wpnews.pro/news/generalized-context-in-cross-attention-for-transfer-learning-of-disjoint-tabular.txt", "jsonld": "https://wpnews.pro/news/generalized-context-in-cross-attention-for-transfer-learning-of-disjoint-tabular.jsonld"}}
