Pytorch sinusoidal positional embedding
WebThere are two ways that rotary embeddings are different from sinusoidal embeddings: Sinusoidal embeddings apply to each coordinate individually, while rotary embeddings mix pairs of coordinates Sinusoidal embeddings add a cos ( m θ) or sin ( m θ) term, while rotary embeddings use a multiplicative factor.
