By hidden I mean that the color of the text is set to be the same as the background color of the page.
In the world of seismic exploration, (ANN) has been very popularly applied, including for color identification, wavelet estimation, speed analysis, shear wave analysis, autotracking reflector, hydrocarbon prediction, reservoir characterization. etc.
example:
"123456789101112131415161718192021222324"
From the picture above shows that, the basic principle of Thread (ANN) is some parameters as input (input layer) which has a hidden layer (multiplication, addition, division, etc.)
example:
"123456789101112131415161718192021222324"
The picture above shows an example of application (ANN) for seismic data.
say have several inputs such as impedance (x1), reflection strength (x2), instantaneous frequency (x3), ...etc.
which will be used to predict reservoir porosity as output. then simply reservoir porosity will be obtained by multiplying each input data sample with a weighting then adding up, then the sum of the inputs becomes the input for the activation function to produce porosity parameters.
The activation function can be either a sigmoid function or a hyperbolic tangent function.
Example:
"123456789101112131415161718192021222324"
Certainly want the results so that the predicted porosity value is as close as possible to the actual porosity value, in other words must have the difference value (read error) between the predicted value and the real value as small as possible, for this purpose in the Thread (ANN) atfor producing maximum results.
