ABSTRACT:
A vector normalizing apparatus which normalizes an input vector or weight vectors by L.sub.2 -norm and adds norm information to the vector before it is normalized. Vector data from an input vector acquiring device (1) is displayed on an input vector display device (2) and transmitted through a vector transmitting device (3) to a normalized vector output device (4). During the transmission of the vector data, L.sub.2 -norm of the vector data is calculated by an L.sub.2 -norm calculating device (5) including a vector component squaring device (7) for squaring each of the components of the displayed vector, a summation device (8) for calculating a total sum of the squared components, and a square-root calculating device (9) for calculating L.sub.2 -norm by obtaining a square root of the result of the summation. The input vector is normalized by a vector component adjusting device (6) using the calculated value of L.sub.2 -norm. Thus, the input vector normalized by the L.sub.2 -norm is delivered onto the normalized vector output device (4).
