Generative AI - Encoder

Encoder

Using a few stages, the encoder converts input tokens into contextualized representations.

  • Input Embeddings: Produces dense vectors from input tokens, which are words or subwords.
  • Positional Encoding: Provides information on the position of each token in the sequence, making up for the transformer architecture's lack of inherent sequence ordering.
  • Multi-Headed Self-Attention: This makes it possible for the model to concentrate on several segments of the input sequence at once, improving each token's contextual comprehension.
  • Feed-Forward Neural Network: Handles the attention mechanism's output.
  • Residual Connections and Layer Normalization: Enhance gradient flow and stabilize training using residual connections and layer normalization.
