One of the recent best attempts at Text-to-SQL is pre-trained language model. Due to structural property SQL queries, seq2seq model takes responsibility parsing both schema items (i.e., tables and columns) skeleton keywords). Such coupled targets increase difficulty correct queries especially when they involve many logic operators. This paper proposes a ranking-enhanced encoding skeleton-aware decoding framework decouple linking parsing. Specifically, for encoder-decode model, its encoder...

In recent years, there have been a growing number of works studying the generalization properties stochastic gradient descent (SGD) from perspective algorithmic stability. However, few them devote to simultaneously and optimization for non-convex setting, especially pairwise SGD with heavy-tailed noise. This paper considers impact noise obeying sub-Weibull distribution on stability-based learning guarantees by investigating its jointly. Specifically, based two novel uniform model stability...

Disentangled Representation Learning (DRL) aims to learn a model capable of identifying and disentangling the underlying factors hidden in observable data representation form. The process separating variation into variables with semantic meaning benefits learning explainable representations data, which imitates meaningful understanding humans when observing an object or relation. As general strategy, DRL has demonstrated its power improving explainability, controlability, robustness, as well...

Few-shot knowledge graph completion is to infer the unknown facts (i.e., query head-tail entity pairs) of a given relation with only few observed reference pairs. Its general process first encode implicit an pair and then match relations Most existing methods have thus far encoded matched pairs by using direct neighbors concerned entities. In this paper, we propose P-INT model for effective few-shot completion. First, infers leverages paths that can expressively two Second, capture fine...
