Encoder-decoderframeworks, in which an encoder network extracts key features of the input data and a decoder network takes that extracted feature data as its input, are used in a variety of deep learning models, like theconvolutional neural network(CNN) architectures used in computer vision tasks...
Deep learning in medical imaging has the potential to minimize the risk of diagnostic errors, reduce radiologist workload, and accelerate diagnosis. Training such deep learning models requires large and accurate datasets, with annotations for all trainin
In this study, we propose a deep learning model named DAC-AIPs based on variational autoencoder and contrastive learning for accurate identification of anti-inflammatory peptides. In the sequence encoding part, the incorporation of multi-hot encoding helps capture richer sequence information. The auto...
