For the problem of people counting in intelligent video surveillance, a method of people counting in complex scenes based on the normalized foreground and corner information is proposed. Thus, to overcome these challenges and exploiting them to support this technological outbreak would be one of the most crucial tasks of modern world. There are many ways that back-propagation can be implemented. The results proved that the use of machine-learning methods can quickly extract land-use types with high accuracy, and provided a better method choice for urban land-use information acquisition. For this purpose, time history response data are collected by solving the high-fidelity model via FEM for a reduced set of parameter values. The problem of overfitting, particularly serious for short records of noisy data, is addressed both by using the statistical method of validation and by adding a complexity term to the cost function (weight-elimination). When the neural network is initialized, weights are set for its individual elements, called neurons. This is where the back propagation algorithm is used to go back and update the weights, so that the actual values and predicted values are close enough. Preprints and early-stage research may not have been peer reviewed yet. Using the latent representation given by the encoder, a feed-forward neural network is efficiently trained to map points from the problem's parametric space to the compressed version of the respective solution matrices.
