Transformer Architecture Components

The final linear layer is responsible for generating probabilities for the next possible word or other targets.

Scalability Advantage

The Transformer architecture's main advantage in terms of scalability is its ability to process input sequences in parallel, unlike RNNs and LSTMs which process sequences sequentially.

Encoder Role

In a full Transformer model, the encoder is responsible for generating a continuous representation of the input sequence.

Flexibility

The Transformer architecture is highly flexible due to its ability to be applied to a wide range of tasks, such as machine translation, text generation, and question-answering.

The purpose of parameter sharing in some Transformer variants is to reduce the number of parameters and improve model efficiency.

Vanishing Gradient Problem

The self-attention mechanism is responsible for addressing the vanishing gradient problem in deep neural networks.

Positional Encodings

The purpose of positional encodings in the Transformer architecture is to preserve the order of the input sequence since the model does not use RNNs or convolution.

Normalization Technique

Layer normalization is commonly used in Transformers to stabilize and accelerate training of deep networks.

Core Innovation

The core innovation in the Transformer architecture is self-attention, which allows the model to focus on different parts of the input sequence when producing an output.

Neural Network Application

A feed-forward neural network (FFNN) is applied to each position separately and identically in each layer of the Transformer.
