Claim 9:
10. The method of claim 9, wherein generating the real component attention matrix comprises:
generating a dot product of a real contemporary transaction metric feature vector and the real historical transaction metric feature vector;
providing the dot product of the real contemporary transaction metric feature vector and the real historical transaction metric feature vector as an input to a softmax layer to generate a real attention feature vector; and
generating a dot product of the real attention feature vector and the real historical target transaction metric feature vector to generate the real component attention matrix;
wherein generating the imaginary component attention matrix comprises:
generating a dot product of the imaginary contemporary transaction metric feature vector and the imaginary historical transaction metric feature vector;
providing the dot product of the imaginary contemporary transaction metric feature vector and the imaginary historical transaction metric feature vector as a input to a softmax layer to generate an imaginary attention feature vector; and
generating a dot product of the imaginary attention feature vector and the imaginary historical target transaction metric feature vector to generate the imaginary component attention matrix.
