Moreover, in Iburi region, there is a high possibility of earthquakes occurring in the future. Before Stock market data space is highly dimensional and, as such, algorithms that try to exploit potential patterns or structure in the price formation can suffer from the so-called curse of dimensionality. doi: 10.1093/bib/bbac073.

All rights reserved. The proposed method is less complex than other unsupervised methods based on a variational autoencoder and it provides better classification results than other familiar classifiers. In this short article, we will explore the potential of 4 different types of autoencoders to capture the dynamic information of stock market prices in a lower and traceable dimension space.

This framework can easily be extended for any other dataset as long as it complies with the standard pytorch Dataset configuration. Finally, we use LSTM to decode vectors and make predictions. The aim of this study is to evaluate the performance of an autoencoder framework based on deep neural network for prediction and susceptibility assessment of regional landslides triggered by earthquakes. First, various sampling strategies showed improved accuracy in landslide susceptibility assessment, which should be analyzed and compare with precision and recall curve in imbalanced data. First, the raw vibration data and labels are input into MSCAE, and then, MSCAE is trained by minimizing the composite loss function.

In general, the results showed that the earthquake dataset, such as distance to fault, distance to epicenter, and PGA was of high importance to the models, whereas the geomorphology, including slope, plan curvature, profile curvature, stream density, and distance to stream, had lower predictive capability in both areas.

However, most of the previous studies failed to judiciously take into account the consistency between the chemical properties of drug and its functions. The model used is super simple but the comparison between the input and the output reveal the ability of the network to abstract few important features such as peaks and lows. They are an unsupervised learning method, although technically, they are trained using supervised learning methods, referred to as self-supervised.
