Study Notes
BERT (Bidirectional Encoder Representations from Transformers)
- BERT is a deep learning model based on Transformers, which enables it to read input text in both directions (left-to-right and right-to-left) simultaneously.
- This capability is known as bidirectionality and is enabled by the introduction of Transformers.
Transformers
- Transformers are a type of deep learning model architecture introduced in 2017, designed to handle sequential data like natural language text or time series data.
- They use attention mechanisms to capture dependencies between elements in the sequence, enabling them to capture long-range dependencies more effectively than RNNs or CNNs.
- Transformers have become the backbone of many state-of-the-art deep learning models in natural language processing (NLP), including BERT, GPT, and others.
Recurrent Neural Networks (RNNs)
- RNNs are good at modeling sequential data like text, audio, or time series data.
- They have a feedback loop, enabling them to have memory, but they suffer from short-term memory and are not good at retaining it long enough.
Word Embeddings
- Word Embeddings represent words as numerical vectors, capturing their meanings and semantic relationships.
- Similar words have similar vector representations, while dissimilar words have different representations.
- Word Embeddings enable computers to grasp relationships between words, handle unseen words, and are efficient for computations within machine learning models.
Word Embeddings Approaches
- Statistical Methods: Techniques like TF-IDF capture a word's importance in a document based on its frequency and how often it appears in other documents.
- Neural Network Methods: Powerful algorithms like Word2Vec and GloVe analyze large text corpora to learn word associations and develop vector representations that capture semantic relationships.
BERT Language Model
- BERT is a machine learning framework for natural language processing (NLP) that can process new information with the context of prior steps.
Recurrent Neural Networks (RNNs) Continued
- Coreference Resolution (CR) is the task of finding all linguistic expressions that refer to the same real-world entity in a given text.
Types of RNNs
- There are several types of RNNs, including long short-term memory (LSTM) networks and gated recurrent units (GRUs), designed to address the problem of vanishing gradients in RNNs.
BERT Uses
- BERT is used by Google to enhance how user search phrases are interpreted, exceling in tasks like question answering, abstract summarization, sentence prediction, and conversational response generation.
