â Frequently Asked Questions
What is a neural network and how is it used in NLP?
A neural network is a computing model inspired by the brain that learns patterns from data. In NLP, networks convert text to numbers and learn to map language inputs to outputs such as classifications, translations, or predictions.
What are the main architectures used in NLP: feedforward, recurrent, and transformer networks?
Feedforward networks process fixed-size inputs in a single pass; recurrent networks (RNNs, LSTMs, GRUs) handle sequences by maintaining memory of prior elements; transformers use self-attention to model relationships between all tokens in a sequence in parallel.
Why are transformers considered powerful for NLP?
Transformers use attention to capture long-range dependencies, enable parallel computation during training, and achieve strong performance on many language tasks.
What are word embeddings and why are they important?
Word embeddings map words to dense vectors that encode semantic meaning and relationships, providing the numerical input that NLP models learn from. Contextual embeddings adapt meaning based on context.
How are NLP neural networks trained?
Models are trained with labeled text data by optimizing a loss function (e.g., cross-entropy) using backpropagation and an optimizer (e.g., SGD, Adam) to adjust network weights.
