How are Transformers revolutionizing NLP?

Transformers are revolutionizing NLP by outperforming recurrent neural networks in sequence problems, thanks to their attention mechanisms.

What is the role of the attention mechanism in Transformers?

The attention mechanism in Transformers allows for an infinite window to reference from, enabling the use of the entire context of a story while generating text.

How are word embeddings used in Transformers?

Word embeddings are mapped to continuous values and positional information is added to the input embeddings using sine and cosine functions.

What is multi-headed attention in Transformers?

Multi-headed attention is a module in a transformer network that uses attention weights to encode information on how each word should attend to all other words in a sequence.

How do Transformers make predictions better than other networks?

Transformers leverage the power of the attention mechanism to make better predictions than other networks, allowing the NLP industry to achieve unprecedented results.

Key insights

🌪️

Transformers are "breaking multiple NLP records and pushing the state-of-the-art," making them a game-changer in the field of natural language processing.
🔍

The Transformers neural network is an attention-based encoder-decoder architecture that maps an input sequence into an abstract continuous representation and generates a single output step by step.
💡

The transformer model uses a clever trick with sine and cosine functions to inject positional information into the input embeddings, allowing the network to have information on two positions of each vector.
🤯

The attention weights in Transformers Neural Network allow the model to be more confident on which words to attend to and drown out irrelevant words.
🤯

Multi-headed attention in transformer networks allows for each head to learn something different, giving the model more representation power.
🤯

The decoder in the Transformers Neural Network is auto regressive and generates the sequence word-by-word, preventing it from conditioning into future tokens.
🤯

The neural network's ability to match encoder input to decoder input and decide which input is relevant is mind-blowing.
🔍

Transformers are usually better than recurrent neural networks at encoding or generating longer sequences due to their architecture, potentially revolutionizing natural language processing.
