چکیده
This study proposed an efficient ECG preprocessing technique, and the preprocessed data was subsequently used to classify atrial fibrillation (AFib) using end-to-end deep neural networks. is significant since early identification of AFib can help prevent mortality. With this in mind, two-fold proposed, which three denoising autoencoders for signal pre-processing were evaluated compared. Denoising (DAEs) utilising convolutional networks (CNNs) as backbones outperformed other two DAE models. As a result, then classification The combination CNN-based model yielded best results, with 99.20 percent accuracy, 99.50 specificity, sensitivity, 99.00 true positive rate. average accuracy algorithms we investigated 96.26 percent, our technique 3.2 more accurate than Furthermore, 24-h processing time only 1.3 s, computationally inexpensive real-time applications. To determine its robustness, framework tested on previously unseen datasets varied proportions arrhythmias, producing 99.10 recall rate 98.50 accuracy.

Remote Sensing Image Classification Based on Stacked Denoising Autoencoder
Focused on the issue that conventional remote sensing image classification methods have run into the bottlenecks in accuracy, a new remote sensing image classification method inspired by deep learning is proposed, which is based on Stacked Denoising Autoencoder. First, the deep network model is built through the stacked layers of Denoising Autoencoder. Then, with noised input, the unsupervised ...
متن کاملSpeech enhancement based on deep denoising autoencoder
We previously have applied deep autoencoder (DAE) for noise reduction and speech enhancement. However, the DAE was trained using only clean speech. In this study, by using noisyclean training pairs, we further introduce a denoising process in learning the DAE. In training the DAE, we still adopt greedy layer-wised pretraining plus fine tuning strategy. In pretraining, each layer is trained as a...

Relational Stacked Denoising Autoencoder for Tag Recommendation
Tag recommendation has become one of the most important ways of organizing and indexing online resources like articles, movies, and music. Since tagging information is usually very sparse, effective learning of the content representation for these resources is crucial to accurate tag recommendation. Recently, models proposed for tag recommendation, such as collaborative topic regression and its...
متن کاملStacked Robust Autoencoder for Classification
In this work we propose an lp-norm data fidelity constraint for training the autoencoder. Usually the Euclidean distance is used for this purpose; we generalize the l2-norm to the lp-norm; smaller values of p make the problem robust to outliers. The ensuing optimization problem is solved using the Augmented Lagrangian approach. The proposed lp -norm Autoencoder has been tested on benchmark deep...
