The model's association with the network layer.

Model	Convolution	Recurrent	Attention	Dense
CRISPR-Net [18]	Yes	Yes	No	Yes
CRISPR-OFFT [25]	Yes	No	Yes	Yes
AttnToMismatch_CNN [17]	Yes	No	Yes	Yes
CNN_std [19]	Yes	No	No	Yes
DeepCRISPR [26]	Yes	No	No	Yes

Notes: 'Yes' means that the model uses this kind of network layer, and 'NO' means it does not.
