Strain (ε) refers to a ratio of expansion/contraction from the original length and is expressed with formula 1. Unit of Strain There is no unit for strain because it represents an expansion (contraction) as a ratio. In other words, it is treated as a “unitless” number. However, to...
In a regression model, the regression coefficient is a measure that tells us how much the dependent variable changes when the independent variable changes by one unit. It represents the average change in the dependent variable for each unit change in the independent variable. ...
A compile unit in an interactive environment like IPython consists of a single statement, whereas it consists of the entire module in case of modules. a, b = "wtf!", "wtf!" is single statement, whereas a = "wtf!"; b = "wtf!" are two statements in a single line. This explains wh...
CuMF is an NVIDIA® CUDA®-based matrix factorization library that optimizes the alternate least square (ALS) method to solve very large-scale MF. CuMF uses a set of techniques to maximize the performance on single and multiple GPUs. These techniques include smart access of sparse data lev...
that are uncorrelated, but have non-unit variance. The covariance matrix for this situation is the diagonal matrix of variances: Σ = diag(σ21,…,σ2p). The square root of Σ is the diagonal matrix D that consists of the standard deviations: Σ = DTD where D = diag(σ1,…,σp)....
