LARGE LANGUAGE MODELS - How They Work

Transformer Neural Networks.

Transformer neural networks are a type of deep learning architecture that is used to process sequential data such as natural language text, genome sequences, sound signals, or time series data. The transformer neural network was first proposed in a 2017 paper titled ‘Attention Is All You Need’ by Ashish Vaswani et al., Google Brain team. It is notable for requiring less training time than previous recurrent neural architectures, such as long short-term memory (LSTM), and its later variation has been prevalently adopted for training large language models on large datasets, such as the Wikipedia corpus and Common Crawl, by virtue of the parallelized processing of input sequence.

Transformers are neural networks that learn context and understanding through sequential data analysis. The Transformer models use a modern and evolving mathematical techniques set, generally known as attention or self-attention. This set helps identify how distant data elements influence and depend on one another. Transformers came into action in a 2017 Google paper as one of the most advanced models ever developed. This has resulted in a wave of advances called “Transformer AI” in machine learning.

Transformers are still being developed and used in various new applications by researchers. Here is a brief explanation of what makes Transformers exciting. Let’s start with what the Transformer model is.

The Transformer model is an encoder-decoder architecture that uses self-attention mechanisms to process input sequences. It can handle sequence-to-sequence (seq2seq) tasks while removing the sequential component. A Transformer, unlike an RNN, does not perform data processing in sequential order, allowing for greater parallelization and faster training.

The Transformer model consists of two main components: an encoder and a decoder. The encoder processes the input sequence, while the decoder generates the output sequence. Both components use self-attention mechanisms to process the input sequence.

The Transformer model has several strengths over other neural network architectures such as RNNs and LSTMs. One strength is that it can handle long-range dependencies more effectively than RNNs or LSTMs. Another strength is that it can be trained more quickly than RNNs or LSTMs because it does not require sequential processing.

However, the Transformer model also has some weaknesses. One weakness is that it requires more memory than other neural network architectures because it processes all inputs simultaneously. Another weakness is that it may not perform as well on tasks that require fine-grained temporal processing.

Transformer neural networks are an exciting development in AI that has the potential to revolutionize many fields such as healthcare and education by generating human-like responses by processing natural-language inputs.
