捣鼓的两天终于写出自己的第一段python代码了。 之前总是想着用Copy的方法来拼凑代码,实际上这种做法是行不通的,也不知是前两天感冒了还是别的原因,拼凑的代码会让你的思维变的混乱,没有统一的逻辑,调试起来更是摸着石头过河,更费劲。所以,能自己写的代码还是要自己动手。 这个代码验证了Autoencoder的Feature Extra...
Autoencoders are divided into two parts: anencoderand adecoder; they are used to perform "representation learning"which is a type of learning thatenables a system to find the representations necessary for feature detection or classification from raw data using a class of machine learning techniques...
This approach has promise for significantly improving the quality of life for persons affected by this condition. The implementation in Python was conducted as part of our experimentation. Upon analyzing the accuracy, it became apparent that the Feature-Based Deep Neural Network (FB-DNN) exhibited ...
Autoencoders which are generally known as a strong tool for feature extraction (Bengio et al. 2013), are being explored to perform unsupervised feature selection. In (Han et al., 2018), authors combine autoencoder regression and group lasso task for unsupervised feature selection named Auto...

Deep autoencoders have been used in many different applications, such as compression, denoising, dimensionality reduction, and feature extraction (Baldi, 2012; Liu et al., 2017). Particularly, using autoencoders to extract features for different tasks show great promise (Ditthapron et al., 2019...
Finally we will perform the analysis of performance for different feature decompositions. The complete experiment on the proposed network architecture was implemented using Python 3.6 and it was executed on a 1.60 GHz machine with 8 GB RAM for all the experiments. Experiments have been conducted on...

Continuous monitoring of blood pressure (BP) is essential for the prediction and the prevention of cardiovascular diseases. Cuffless BP methods based on non-invasive sensors integrated into wearable devices can translate blood pulsatile activity into con
