Deep Learning Foundations and Key Architectures in Natural Language Processing
Deep learning has transformed natural language processing (NLP) by enabling machines to automatically learn complex features from raw language data using multi-layer neural networks. Core architectures such as Recurrent Neural Networks (RNNs), Long Short-Term Memory (LSTM) networks, Gated Recurrent Units (GRUs), Convolutional Neural Networks (CNNs), and the Transformer model have become foundational for a wide range of NLP tasks. These models excel at capturing semantic and contextual relationships in text, which is essential for understanding and generating human language Yang2024Yang2019Lauriola2021+4 MORE.
