Deep Learning - IQ - 6. Natural LanguageProcessing (NLP)
What is natural language processing (NLP)? - answer: Natural Language Processing
(NLP) is a field of artificial intelligence that focuses on the interaction between
computers and human language. It involves the development of algorithms and models
to enable computers to understand, interpret, and generate human language.
Explain the bag-of-words model in NLP. - answer: The bag-of-words model represents a
document as an unordered set of words, ignoring grammar and word order but keeping
track of word frequency. It creates a "bag" of words, and each document is represented
by a vector where each element corresponds to the frequency of a specific word.
What is tokenization in the context of NLP? - answer: Tokenization is the process of
breaking down a text into smaller units, known as tokens. Tokens can be words,
subworlds, or characters. Tokenization is a crucial step in NLP for various tasks,
allowing the model to process and understand the structure of the text.
Describe the purpose of word embeddings. - answer: Word embeddings are dense
vector representations of words in a continuous vector space. They capture semantic
relationships between words, enabling algorithms to understand the context and
meaning of words in a more nuanced way compared to traditional one-hot encodings.
Popular word embedding methods include Word2Vec and Glove.
What are Word2Vec and GloVe? - answerAnswer: Word2Vec and GloVe are popular
word embedding techniques. Word2Vec uses neural networks to learn vector
representations of words based on their context in a given corpus. GloVe (Global
Vectors for Word Representation) is another method that constructs word vectors based
on the global statistical information of word co-occurrence.
Explain the concept of a recurrent neural network for sequence modeling in NLP. -
answerAnswer: Recurrent Neural Networks (RNNs) are used for sequence modeling in
NLP to process sequences of data, such as sentences or documents. RNNs maintain
hidden states that capture information from previous elements in the sequence, allowing
them to model dependencies and context in sequential data.
What is the transformer architecture, and how is it used in NLP? - answerAnswer: The
transformer architecture is a type of neural network architecture designed for sequence-
to-sequence tasks. It relies on self-attention mechanisms to capture long-range
dependencies efficiently. Transformers are widely used in NLP tasks, and models like
BERT and GPT-3 are built upon the transformer architecture.
