Model variantsExplanation

TAFM_aeTAFM_ae refers to the removal of the convolutional autoencoder from the TAFM model.
TAFM_aTAFM_a refers to the removal of the outermost multiheaded attention mechanism based on the TAFM model.
TAFM_ae_aTAFM_ae_a refers to the TAFM model with both the outermost multiheaded attention mechanism and the convolutional autoencoder removed.
TAFM_lTAFM_l refers to the TAFM model with the LSTM removed.
TAFM_bTAFM_b refers to the removal of BiLSTM_Attention from the TAFM model.
TAFM_cTAFM_c refers to the TAFM model with the textCNN removed.
TAFM_l_bTAFM_l_b refers to the TAFM model with both LSTM and BiLSTM_Attention removed.
TAFM_l_cTAFM_l_c refers to the base of TAFM model with both LSTM and TextCNN removed.
TAFM_b_cTAFM_b_c refers to the removal of both BiLSTM_Attention and TextCNN on top of the TAFM model.
TAFM_b_l_cTAFM_b_l_c refers to the TAFM model with BiLSTM_Attention, LSTM and TextCNN removed at the same time; in other words, this variant removes the entire text module.
