Why Are Sines and Cosines Used For Positional Encoding?

WebNov 24, 2024 · An alternative approach to positional embeddings is to choose a static function that maps an integer inputs to real-valued vectors in a way that captures the inherent relationships among the positions. That is, it captures the fact that position 4 in an input is more closely related to position 5 than it is to position 17. WebIn our approach, we use a sinusoidal positional embedding technique to represent the position of each token in the text, as well as no layer normalization embedding. Our code generation approach, MarianCG, is based on fine-tuning a machine translation pre-trained language model.
