A Transformer is composed of stacked encoder layers and decoder layers. Like earlier seq2seq models, the original transformer model used an encoder-decoder architecture. The encoder consists of encoding layers that process all the input tokens together one layer after another, while the decoder consists of decoding layers that iteratively ...
That development led to the emergence of large language models such as BERT (2018) [28] which was a pre-trained transformer (PT) but not designed to be generative (BERT was an "encoder-only" model). Also in 2018, OpenAI published Improving Language Understanding by Generative Pre-Training , which introduced GPT-1 , the first in its GPT series.
Transformer architecture is now used in many generative models that contribute to the ongoing AI boom. In language modelling, ELMo (2018) was a bi-directional LSTM that produces contextualized word embeddings, improving upon the line of research from bag of words and word2vec. It was followed by BERT (2018), an encoder-only Transformer model. [33]
The Transformers: The Movie, Early scripts for the movie say he was killed during Unicron's attack on Cybertron, but the scene did not make the final cut. Corey Burton: Unknown Cold, brutal, scientific approach to war. Loyal to Megatron, he was left in charge of Cybertron when Megatron left. [127]
Generative Pre-trained Transformer 2 (GPT-2) is a large language model by OpenAI and the second in their foundational series of GPT models. GPT-2 was pre-trained on a dataset of 8 million web pages. [2] It was partially released in February 2019, followed by full release of the 1.5-billion-parameter model on November 5, 2019. [3] [4] [5]
Generative Pre-trained Transformer 3 (GPT-3) is a large language model released by OpenAI in 2020. Like its predecessor, GPT-2 , it is a decoder-only [ 2 ] transformer model of deep neural network, which supersedes recurrence and convolution-based architectures with a technique known as " attention ". [ 3 ]
The list of symbols can be used to train into a standard autoregressive transformer (like GPT), for autoregressively generating an image. Further, one can take a list of caption-image pairs, convert the images into strings of symbols, and train a standard GPT-style transformer.
Optimus Prime (voiced by Peter Cullen) is the leader of the Autobots, the last descendant of the Dynasty of Primes and keeper of the Matrix of Leadership.Optimus Prime transforms into a 1994 red and blue Peterbilt 379 semi-trailer truck in the first three films, a rusty 1973 Marmon HDT-AC 86 semi cab-over truck in the beginning of the fourth film, and later a blue and red 2014 Western Star ...
