Can AI help automate human-easy but computer-hard data preparation tasks that burden scientists, practitioners, and crowd workers? We answer this question by presenting RPT, a denoising autoencoder for tuple-to-X models (" X " could be tuple, token, label, JSON, so on). RPT is pre-trained tuple-to-tuple model corrupting the input tuple then learning to reconstruct original tuple. It adopts Tran...

BACKGROUND Structural brain abnormalities are associated with late-life major depression, with numerous studies reporting increased white matter hyperintensities (WMH) and reduced cortical/subcortical grey matter volumes. There is strong evidence linking vascular disease to WMH, but limited evidence on its association with subcortical volumes. AIMS To investigate the relationship of orthostat...

To construct the network organizational structure of college students’ educational management and realize informatization development management, construction method is proposed based on distributed network. MySQL PostgreSQL are used as bottom data models network-based education multisource information scheduling method, which to transaction identifier (TID) labeling tuple model The initial top...

A class of relational databases has low degree if for all $\delta>0$, but finitely many in the have at most $n^{\delta}$, where $n$ is size database. Typical examples are bounded or by $\log n$. It known that over a having degree, first-order boolean queries can be checked pseudo-linear time, i.e.\ $\epsilon>0$ time $n^{1+\epsilon}$. We generalize this result considering query evaluation. show ...

Let k ≥ 1 be an integer and G a graph of minimum degree δ ( ) − 1. A set D ⊆ V is said to -tuple dominating if | N [ v ] ∩ for every vertex ∈ ), where represents the closed neighbourhood . The cardinality among all sets domination number In this paper, we continue with study classical parameter in graphs. particular, provide some relationships that exist between other parameters, like multiple ...

BACKGROUND To describe grey-scale sonographic findings in lower extremity entheses in healthy children. METHODS Healthy patients referred to Orthopedic Surgery or Adolescent Medicine outpatient clinics or their siblings ages 5-18 years were recruited. Grey-scale ultrasound was performed on 3 entheseal sites bilaterally, the proximal patellar ligament insertion (PPL), distal patellar ligament ...

To investigate a model to simulate wheat dry matter accumulation, three wheat cultivars with different tillering abilities were grown at three densities each in a field experiment. Five simulation models with high correlation coefficients for relative dry matter accumulation were established by the method of normalized. Among these models, the Richards equation was the best in fitting and forec...

As one of the core functions autonomous driving vehicles under special roads, intelligent barrier avoidance function plays an important role in improving traffic efficiency and ensuring safety. Scientific, reasonable, comprehensive evaluation methods can provide basis for before their use. The index system is constructed ability mode against different barriers. weights qualitative indicators th...

Course evaluation is an important and necessary means to improve the level of course. A new course evaluation method based on fractional grey relational distance and analytic hierarchy process (AHP) is proposed in this paper. Firstly, the proportion of the different influence factors can be determined through constructing judging-matrix and calculating-back-to-one and dealing with the checkout ...

Theorem 1. The nth derivative of the function 1/r along n constant (translation-invariant) vector fields in R coincides on the sphere with a spherical function of degree n. Any nonzero spherical function of degree n can be obtained by this construction from some n-tuple of nonzero vector fields. These n fields are uniquely defined by the function (up to multiplication by nonzero constants and p...
