Pytorch sinusoidal positional embedding

WebThe positional encoding outputs X + P using a positional embedding matrix P ∈ R n × d of the same shape, whose element on the i th row and the ( 2 j) th or the ( 2 j + 1) th column is (11.6.2) p i, 2 j = sin ( i 10000 2 j / d), p i, 2 j + 1 = cos ( i 10000 2 j / d). At first glance, this trigonometric-function design looks weird. 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.
