Linear approximation - Study guides, Class notes & Summaries

Pete 401 Exam 1 Questions & Answers 2024/2025 One way to derive an explicit approximation of the reservoir simulation equation is to use central differences for spatial derivatives, and forward differences for time derivatives. - ANSWERSTrue, Blah A Material Balance Model for a Volumetric Undersaturated Oil Reservoir neglects reservoir flow effects and assumes constant permeability - ANSWERSFalse, it... Because the Partial Differential Equation (PDE) of the reservoir simulation flow e...

What is PCA? (5 key points) Principal Component Analysis is a statistical technique used for dimensionality reduction, crucial when dealing with high-dimensional data in machine learning. It works by transforming original variables into new ones, called principal components, which are linear combinations of the original variables. Key Points: 1. Principal Components: Principal components are the directions in the data that maximize variance. The first principal component captures the most...

Typical shapes of unstructured grid cells used in 2D grids are quadrilateral and ______________________ correct answer: triangular a grid is ___________ if any line connecting centers of neighboring cells face between the cells correct answer: orthogonal one disadvantage of using unstructured grids is slower _____________ correct answer: convergence it is recommended for flows with attached boundary layers that the grid includes a layer of thin quadrilateral or hexahedral cells adjac...

Logistic Regression - Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to the predict...
