WebPosition Noise (RPN) algorithm, a novel data augmentation technique that operates at the word vector level. RPN modifies the word embeddings of the original text by introducing noise based on the existing values of selected word vectors, allowing for more fine-grained modifications and better capturing natu-ral language variations. WebVectors are defined in cylindrical coordinates by ( ρ, φ, z ), where ρ is the length of the vector projected onto the xy -plane, φ is the angle between the projection of the vector onto the xy -plane (i.e. ρ) and the positive x -axis (0 ≤ φ < 2 π ), z is the regular z -coordinate. ( ρ, φ, z) is given in Cartesian coordinates by: or inversely by:
