in coalbed methane (CBM) reservoirs in unconventional oil and gas reservoir exploration, this paper carries out the extraction and comparison of fractures on the basis of the gradient structure tensor (GST) method, combining with the real geological conditions of the Yanchuannan (...
The analysis of CNN visualisation shows some interesting results, such as lower layers that contain representations of simple structures, e.g., lines and edges (local invariance). At the same time, deeper layers capture object-specific information and learn complex compositions. Unlike [36], the ...
2.7Sample efficiency analysis In all gradient-free methods, sampling a vector of policy parametersθprovides an exact information about its utilityJ(θ). However, theJfunction can be stochastic, in which case one value ofJ(θ)only contains partial information about the value of thatθ. Anyways,...
Static code analysis: Code quality tests are implemented using flake8, black, isort, safety, and radon. Test automation: Tox is used for test automation.Project StructureThe following is the directory structure of the project:examples/: This directory contains example files for the titanic dataset...
The effects of combining rotation with a non-isotropic mobility tensor (γ in (3) promoted to a matrix) will be reported elsewhere. To give numbers, assume the Brownian particle to be something like a polystyrene ball of radius R ~ 1 μm, mass m ~ 4.2 × 10−12...

In this paper, spectrum analysis is performed on the topographic data (see Fig. 6). It is observed that the high-frequency (short-wavelength) portion of the terrain does not contain more information than the measured gravity. In frequency bands with resolutions exceeding 15 km, the gravity ...
Throughout this analysis we will make heavy use of the singular value decomposition of the weight matrix, which defines matricesU,S, andVsuch thatW = USVT. The matrixSis diagonal, and the diagonal elements are called the singular valuesσi. TheUandVmatrices are orthonormal. ...

That's right. Bootstrap aggregation is the process of bootstrapping many times and then doing some analysis and aggregating. In the case of ensemble methods, that's exactly what we're going to be talking about. We're going to be doing bootstrap aggregating as we can see just now. But...
