Key Terms
Natural Language Processing:
Natural Language Processing (NLP) leverages computational algorithms to analyze, interpret, and generate human language, enabling applications such as machine translation, sentiment analysis, and chatbots. NLP employs techniques like tokenization, syntactic parsing, and deep learning models, including transformers and recurrent neural networks, to process textual data efficiently. Explore the latest advancements in NLP architectures and their impact on enhancing human-computer interaction.
Tokenization
Tokenization in natural language processing (NLP) involves breaking down text into meaningful units like words, subwords, or characters to enhance model understanding and performance. In biosignal decoding, tokenization refers to segmenting continuous physiological signals--such as EEG or ECG--into discrete, analyzable segments or events for pattern recognition and classification. Explore further to understand how tokenization techniques differ and impact processing efficiency in both domains.
Semantic Analysis
Natural language processing (NLP) excels in semantic analysis by interpreting context, sentiment, and meaning from textual data using techniques like word embeddings and transformer models. Biosignal decoding focuses on translating physiological signals such as EEG or ECG into meaningful information, often leveraging machine learning for pattern recognition but with distinct challenges in semantic interpretation.
