BERT language model

What is BERT (Bidirectional Encoder Representations from Transformers) and how is it used?

BERT is a groundbreaking language model developed by Google AI in 2018. It has changed the game in natural language processing (NLP). Unlike old models, BERT reads text in both directions, understanding left and right context. This lets it grasp language nuances better. Thanks to this, BERT excels in many NLP tasks. It does well…

word embeddings

What are word embeddings, and how are they used in NLP?

Word embeddings are key in natural language processing (NLP). They change how machines understand text. These numeric forms of words in a lower-dimensional space hold the meaning and structure of language. This lets machines see how words relate and are similar. Word embeddings are vital for many NLP tasks. These include text classification, named entity…

n-gram models

What is the difference between a unigram, bigram, and n-gram model?

In natural language processing, unigrams, bigrams, and n-grams are statistical models. They help predict the probability of word sequences. These models uncover patterns in text, aiding in tasks like language modeling and sentiment analysis. A unigram model looks at each word alone, ignoring the word before it. Bigrams, on the other hand, consider the word…

natural language processing

What is named entity recognition (NER) in NLP?

Named entity recognition (NER) is a way to extract information from text. It finds and sorts out key information in text called named entities. These entities are important subjects in a text, like names, places, companies, events, and products. NER helps machines understand and sort these entities. This is useful for tasks like text summarization,…

stop words

How do stop words impact the performance of an NLP model?

Natural Language Processing (NLP) helps computers understand human language. Stopwords are key in NLP tasks like text classification, information retrieval, and sentiment analysis. This article will look at how stop words affect NLP model performance. Stop words are common words like “the,” “a,” “and,” and “in.” They might seem unimportant, but they can greatly affect…

tokenization

What is tokenization in NLP and why is it important?

Natural Language Processing (NLP) is a field that lets machines understand and create human language. Tokenization is key in NLP. It breaks down text into smaller parts called tokens. These tokens can be words, characters, or parts of words. Tokenization is vital because it turns raw text into a format machines can work with. It…

transformer

How do transformers work in NLP tasks like translation and text generation?

Transformer models have changed the game in natural language processing (NLP). They excel in tasks like machine translation and text generation. These models use attention mechanisms to understand word relationships, processing sequences in parallel. This approach has led to top results in many NLP tasks, changing how AI interacts with and creates human language. At…

Natural Language Processing

How does sentiment analysis work in NLP?

In today’s digital world, understanding text data is key for businesses. Sentiment analysis, or opinion mining, helps find and sort out feelings in text. It lets companies know what people think about their products or services by reading their emotions and opinions. Sentiment analysis uses NLP to figure out the mood of text, like if…

Recurrent Neural Networks

What is a Recurrent Neural Network (RNN), and how is it used in sequence prediction?

Recurrent Neural Networks (RNNs) are a special kind of deep learning model. They are great at handling data that comes in a sequence, like time series data. Unlike regular neural networks, RNNs remember what came before to help with the current task. This makes them perfect for tasks like understanding language, recognizing speech, and predicting…

Deep Learning Activation Functions

What are common activation functions used in deep learning, such as ReLU and Sigmoid?

Activation functions are key in deep learning models. They decide what the neural network outputs. They make sure the network can learn complex data relationships. The Sigmoid, Tanh, and Rectified Linear Unit (ReLU) are top choices. These functions have special traits and uses. They affect how well and how a network trains. The Sigmoid function…
