The network can be trained directly in This paper introduces the Convolutional Auto-Encoder, a hierarchical unsu-pervised feature extractor that scales well to high-dimensional inputs. We proposed a one-dimensional convolutional neural network (CNN) model, which divides heart sound signals into normal and abnormal directly independent of ECG. Feature Extraction An autoencoder is a neural network that encodes its input to a latent space representation attempts to decode this representation to recover the inputs.17 In a CAE, the layers responsible for encoding and decoding the latent space are convolutional, using shared weights to kernels to extract features from their input. The convolutional layers are used for automatic extraction of an image feature hierarchy. ScienceDirect ® is a registered trademark of Elsevier B.V.

In this process, the output of the upper layer of the encoder is taken as the input of the next layer to achieve a multilearning sample feature. Training a convolutional autoencorder from scratch seems to require quite a bit of memory and time, but if I could work off of a pre-trained CNN autoencoder this might save me memory and time. An autoencoder is composed of an encoder and a decoder sub-models. The deep features of heart sounds were extracted by the denoising autoencoder (DAE) algorithm as the input feature of 1D CNN.
