Cosine similarity induced metricNonnegative matrix factorization (NMF) is a low-rank decomposition based image representation method under the nonnegativity constraint. However, a lot of NMF based approaches utilize Frobenius-norm or KL-divergence as the metrics to model the loss functions. These ...
which is suitable for downstream graph-level classification. The objective is of a slightly different form from the NCE loss. Because of this we use a generalization of the formulation presented
Loss Up. Two variation trends that can occur in-trans genes are (i) In-trans Up: upregulated gene in scRNA-seq gene expression (U) and (ii) In-trans Down: downregulated gene in scRNA-seq gene expression
The Margin Ranking Loss function is used as the training loss function, aiming to ensure that the score of positive samples is higher than that of negative samples. The model’s parameters are updated through stochastic gradient descent. The formula of loss function is as follows: (17)L=∑i...
Cases with Splicing mutation with associated one copy loss were classified as Bi-allelic splicing or splicing LOH, and finally tumors with Missense mutations with associated one copy loss were annotated as missense LOH. While these tumors were classified as LOH mutants, the remaining mutant copy of...
Negative life event, Language pattern mining, Analogical reasoningBackground: Feelings of depression can be caused by negative life events (NLE) such as the death of a family member, a quarrel with one's spouse, job loss, or strong criticism from an authority figure. The automatic and ...
Cosine similarity of fate between real sisters and random sisters is summarized in the adjoining plot for all clones. These 105 clones were derived over 4 independent experiments. (E) Genes (613 of 12,850) that predict clonal fate bias for the indicated DC subtypes. The closer a gene is ...
However, a lot of NMF based approaches utilize Frobenius-norm or KL-divergence as the metrics to model the loss functions. These metrics are not dilation-invariant and thus sensitive to the scale-change illuminations. To solve this problem, this paper proposes a novel robust NMF method (CSNMF...
As can be seen from Table 5, after replacing the cosine similarity loss function in BAPG with T-PSC, the model performance is improved compared to both the original model and BAPG. Especially when tIoU = 0.7, taking TriDet as an example, T-PSC can obtain a gain of 0.1% based on BA...
