# SongCi 

\[[Github Repo](https://github.com/shenxiaochenn/SongCi)\]

SongCi is a multi-modal deep learning model tailored for forensic pathological analyses.
The architecture consists of three main parts, i.e., an imaging encoder for WSI feature extraction, a text encoder for the embedding of gross key findings as well as diagnostic queries, and a multi-modal fusion block that integrates the embeddings of WSI and gross key findings to align with those of the diagnostic queries.

# How to use SongCi ?


###  patch-level feature extraction

```python

import vision_former as vits
import torch

model = vits.__dict__['vit_small'](patch_size=16, num_classes=0)
model.load_state_dict(torch.load("./songci.pth"))


for p in model.parameters():

    p.requires_grad = False


model.eval()

aa=torch.randn((10,3,224,224))

print(model(aa).shape)

```

### multi-modality fusion

```python

from model_fusion_plip import fusionblock2,fusionblock_wonum
import torch

from transformers import  CLIPModel

def model_fusion(depth=2,noise_ratio=0.5, gate=True,num_em=True):
    prototype_all = torch.load("songci_prototype.pt",map_location="cuda") # import the prototype space
    disease_model = CLIPModel.from_pretrained("vinid/plip")
    disease_model.eval()

    if num_em == True:

        model_fusion = fusionblock2(prototype_all=prototype_all, text_model=disease_model, disease_model=disease_model, depth=depth, noise_ratio=noise_ratio, gated=gate)
    else:
        model_fusion = fusionblock_wonum(prototype_all=prototype_all, text_model=disease_model, disease_model=disease_model,
                                    depth=depth, noise_ratio=noise_ratio, gated=gate)

    return model_fusion

model = model_fusion()

model.load_state_dict(torch.load("fusion_checkpoint.pth",map_location="cpu"))
print("finish!!!!")
```
