A Review of Hybrid and Ensemble in Deep Learning for Natural Language Processing
It provides a comprehensive overview for researchers and practitioners in NLP, but it is incremental as it reviews existing methods without introducing new techniques.
This review paper explores hybrid and ensemble deep learning models in NLP, covering tasks like sentiment analysis and machine translation, and synthesizes insights on architectures, performance, and challenges to guide researchers and practitioners.
This review presents a comprehensive exploration of hybrid and ensemble deep learning models within Natural Language Processing (NLP), shedding light on their transformative potential across diverse tasks such as Sentiment Analysis, Named Entity Recognition, Machine Translation, Question Answering, Text Classification, Generation, Speech Recognition, Summarization, and Language Modeling. The paper systematically introduces each task, delineates key architectures from Recurrent Neural Networks (RNNs) to Transformer-based models like BERT, and evaluates their performance, challenges, and computational demands. The adaptability of ensemble techniques is emphasized, highlighting their capacity to enhance various NLP applications. Challenges in implementation, including computational overhead, overfitting, and model interpretation complexities, are addressed alongside the trade-off between interpretability and performance. Serving as a concise yet invaluable guide, this review synthesizes insights into tasks, architectures, and challenges, offering a holistic perspective for researchers and practitioners aiming to advance language-driven applications through ensemble deep learning in NLP.
