Web24 aug. 2024 · Different ways of representing cross product. (Source: mathsisfun) An important observation here is that for vectors facing the same direction the cross product is zero. a x b = 0 as sin (0) = 0. Cross product is the product of two vectors a and b such that the resultant vector is perpendicular to both a and b..

WebHow to check if two vectors are equal in R? You can use the identical () function in R to compare two vectors for equality. Pass the two vectors as arguments to the indentical () function. The following is the syntax – identical(vec1, vec2) It returns TRUE if both vectors contain the same elements in the same positions.

WebMotivated by these findings, we formulate the vector-scaling(VS) loss, that captures existing techniques as special cases. Moreover, we introduce a natural extension of the VS-loss to group-sensitive classification, thus treating the two common types of imbalances (label/group) in a unifying way.
