May 15, 2024 · Positional encodings utilize a specific mathematical formula to generate a unique encoding for each position in the input sequence. Here’s a closer look at the methodology: Formula for Positional Encoding: For each position ?p in the sequence, and for each dimension 2?2i and 2?+12i+1 in the encoding vector:

Jan 5, 2023 · In this tutorial, you discovered positional encoding in transformers. Specifically, you learned: What is positional encoding, and why it is needed. How to implement positional encoding in Python using NumPy; How to visualize the positional encoding matrix; Do you have any questions about positional encoding discussed in this post?

The positional encoding outputs \(\mathbf{X} + \mathbf{P}\) using a positional embedding matrix \(\mathbf{P} \in \mathbb{R}^{n \times d}\) of the same shape, whose element on the \(i^\textrm{th}\) row and the \((2j)^\textrm{th}\) or the \((2j + 1)^\textrm{th}\) column is
