Recently, recommendation system (RS) models relying on graph neural networks (GNNs) have been widely developed, but the increase of GNN layers inevitably leads to over-smoothing problems. Meanwhile, most of the current KG-based negative sampling strategies randomly collect negative samples from ...
Sample 1 Related toNegative Reviews Peer ReviewDental Group, after consultation with the Joint --- Operations Committee, shall implement, regularly review, modify as necessary or appropriate and obtain the commitment of Providers to actively participate in peer review procedures for Providers. Dental...
For a specific source sample xixi and its predicted label y, they input (xi,y)(xi,y) into a discriminator D(xi,y)D(xi,y) and calculated the weight w(xi,yi)w(xi,yi) by D(xi,y)/(1−D(xi,y))D(xi,y)/(1−D(xi,y)), which represents the distribution density ratio of ...
However, the recommendation performance is incapable of particular applications in terms of data sparsity and sample diversity. In this paper, we propose a new incremental recommend algorithm by improving incremental nonnegative matrix factorization based on three-way decision, called Three-way Decision ...
In each iteration, the function selected negative samples with the same number of positive samples from the negative sample pool to form a sampling table. According to the recommendation of previous studies (Chen et al., 2018), we determined that 70% of data in a sampling table was randomly...
WCG families were selected for this sample if they had completed the post-assessment (n = 41; see also [35]). There was one missing value for an item of the ODD scale in the EG both at baseline and at post-assessment. The ODD scale score for the family concerned was determined ...
The noninferiority hypothesis, sample size calculations, and hierarchical test procedures to assess superiority are detailed in the eMethods in Supplement 2. The analysis of the primary end point was to be performed when the number of events had reached 498, with a minimum median follow-up of ...
Sample headers file: all: Accept: application/json /path/0.1/auth: jwt: XXXXXXXXXXXXX /path/0.2/cancel: jwt: YYYYYYYYYYYYY This will add the Accept header to all calls and the jwt header to the specified paths. You can use environment (system) variables in a headers file using: $$...
The final sample used for this research were 347 after removing the 33 invalid data (91.3% response rate). The samples satisfy the minimum requirements for the SEM test (Balakrishnan & Griffiths, Citation2018). A non-probability sampling, the convenience sampling technique was used in this study...
However, these studies had relatively small sample sizes and did not incorporate PSAD as a dichotomous variable into multivariable regression to further test its statistical significance. Therefore, based on a cohort of 607 mpMRI-negative patients from our institution, this study found that PSAD more...
