transformer layer is a key component of the Transformer architecture,
which is widely used in natural language processing tasks such as
machine translation, text summarization, and more. A transformer layer
typically consists of the following parts:\n\n1. Multi-Head
Self-Attention Mechanism: This mechanism allows the model to weigh the
importance of different words in a sequence relative to each other. It
computes attention scores for each word in the input sequence and uses
these scores to create a weighted representation of the input. This
helps the model to capture long-range dependencies and contextual
information more effectively.\n\n2. Layer Normalization: Layer
normalization is applied after the multi-head self-attention
mechanism. It helps in stabilizing the training process and improving
the model's convergence by normalizing the input across the features
rather than across the batch. It computes the mean and variance of the
input and normalizes it accordingly.\n\n3. Position-wise Feed-Forward
Networks (FFN): These are fully connected feed-forward networks
applied to each position separately and identically. They consist of
two linear layers with a ReLU activation function in between. The
purpose of the FFN is to introduce non-linearity into the model and to
process the information obtained from the self-attention
mechanism.\n\n4. Residual Connections: Residual connections, also
known as skip connections, are used to connect the input of a layer to
its output. They help in mitigating the vanishing gradient problem and
allow the model to learn more complex functions. In a transformer
layer, residual connections are used to connect the input of the
multi-head self-attention mechanism to its output and the input of the
position-wise FFN to its output.\n\n5. Dropout: Dropout is a
regularization technique used to prevent overfitting in neural
networks. It randomly drops out a certain percentage of neurons during
training, forcing the model to learn more robust features. In a
transformer layer, dropout is applied after the multi-head
self-attention mechanism, layer normalization, and position-wise
FFN.\n\nIn summary, a transformer layer processes the input logits
through a multi-head self-attention mechanism to capture contextual
information, applies layer normalization to stabilize training, uses
position-wise feed-forward networks to introduce non-linearity, and
employs residual connections and dropout for better learning and
