Vectorisation in the two dimensional case: this reshaping process converts each galaxy image into a point within a high-dimensional vector space. The first 642 values correspond to the values of the pixels in the metallicity map, followed by the values of the other maps. This allows for a unique vector-based representation of each galaxy as I ∈ ℝd, where d is the dimension (Equation (1)).
