The architecture of an autoencoder may vary, as we will see, but generally speaking it includes an encoder, that transforms the input into a lower dimensional representation, and a decoder, which tries to reconstruct the original input from the lower dimensional representation. Each grid cell of the landslide susceptibility map had a unique value representing the landslide susceptibility value. In current networks, such systems are becoming more important as the number and variety of attacks increase along with the volume and sensitiveness of the information exchanged. The 12 susceptibility maps, including the landslide susceptibility index, indicated the various spatial distributions of the landslide susceptibility values in both PM and the M. The highly accurate models explicitly distinguished the potential areas of landslide from stable areas without expanding the spatial extent of the potential landslide areas.

Trajectory prediction of the ego vehicle is essential for advanced driver assistance systems to function properly. So stacked autoencoder can automatically learn hidden relationship between k-mer sequence motif, it will extract the most informative high-level features from its compressed representation, which avoids curse of dimensionality via eliminating . The autoencoder, which is a special type of multi-layer perceptron, is an artificial neural network. The tool could be useful to guide the deployment of disaster relief operations and mitigation strategies. An autoencoder is composed of encoder and a decoder sub-models. The final prediction results obtained from the autoencoder modeling were evaluated using the testing data set based on qualitative and quantitative analyses to validate the performance of the models. The susceptibility values were mainly distributed around the two opposite extremes between 0 and 1. The https:// ensures that you are connecting to the 2018). The true negative rate (TNR) measures the proportion of actual negatives that are correctly identified (3). The experimental results led to the following conclusions.
