6 (b) Use your graph to estimate the number of books to be printed if the cost of printing each book is $15.](c) (i) By drawing a tangent, find the gradient of the curve at the point where x=300.[2](ii) Describe briefly what this gradient represents.1](d) In order to sell...
The small time asymptotics of the heat kernel at the cut locus We study the small time asymptotics of the gradient and Hessian of the logarithm of the heat kernel at the cut locus, giving, in principle, complete expans... R Neel - 《Communications in Analysis & Geometry》 被引量: 40发表...
We propose an approach that offers an extension that estimates the significance of features by analysing the gradient descent of a pairwise layer within a model. The changes that occur with the weights and gradients throughout training provide a profile that can be used to better understand the ...
Minimizing Lℒ of (2.3) with respect to w0w0 involves computing the gradient of Lℒ with respect to w0w0 , i.e. δL/δw0δℒ/δw0 . Following [13], we obtain (2.4) δLδw0=⎛⎜⎜⎝δLδu0δLδp0δLδϕ0⎞⎟⎟⎠=(−^u00−^ϕ0).δℒ...
It appears that the peak concentration of tritum was reached in about one year, making the average groundwater velocity 1760 ft/yr. The predicted average velocity for the tracer test based on the estimated gradient and permeability and an assumed porosity was 320 ft/yr, making this estimate ...
It is important to mention that the Cab estimation at the field scale is particularly complex due to the vertical gradient of Cab, which increases from the stem to the upper leaves and may explain the poor performances of the ANN. In addition, these results (errors) must also be discussed ...
Owing to the complexity of the causes of earth fissures, the prediction of earth fissures remains a challenging task. In this study, we assess earth fissure hazard susceptibility mapping through four advanced machine learning algorithms, namely random forest (RF), extreme gradient boosting (XGBoost)...
There has been much controversy about the reality of the Guyton's model of circulation [ 1 , 2 ]. According to this model, systemic venous return is proportional to the pressure gradient for venous return divided by the resistance to venous return. The pressure gradient for venous return is ...
