a The embedding tensor of 20 types of amino acids. b The P is the weight matrix of a sequence, where a row corresponds to a position in the sequence, columns represent 20 types of amino acids, and n denotes sequence length. c The O is a one-hot matrix, and each row in O is a one-hot vector converted from the corresponding numerical index of amino acids. d The Lp is the sequence tensor with evolutionary information
