# SecureBERT+ |
|
This model represents an improved version of the [SecureBERT](https://huggingface.co/ehsanaghaei/SecureBERT) model, trained on a corpus eight times larger than its predecessor, leveraging the computational power of 8xA100 GPUs. This version, known as SecureBERT+, brings forth an average improvment of 9% in the performance of the Masked Language Model (MLM) task. This advancement signifies a substantial stride towards achieving heightened proficiency in language understanding and representation learning within the cybersecurity domain. |
|
|
|
|
|
SecureBERT is a domain-specific language model based on RoBERTa which is trained on a huge amount of cybersecurity data and fine-tuned/tweaked to understand/represent cybersecurity textual data. |
|
|
|
## Dataset |
|
 |
|
|
|
## Load Model |
|
SecureBER+T has been uploaded to [Huggingface](https://huggingface.co/ehsanaghaei/SecureBERT_Plus) framework. |
|
|
|
```python |
|
from transformers import RobertaTokenizer, RobertaModel |
|
import torch |
|
|
|
tokenizer = RobertaTokenizer.from_pretrained("ehsanaghaei/SecureBERT_Plus") |
|
model = RobertaModel.from_pretrained("ehsanaghaei/SecureBERT_Plus") |
|
|
|
inputs = tokenizer("This is SecureBERT Plus!", return_tensors="pt") |
|
outputs = model(**inputs) |
|
|
|
last_hidden_states = outputs.last_hidden_state |
|
``` |
|
|
|
## Fill Mask (MLM) |
|
Use the code below to predict the masked word within the given sentences: |
|
|
|
```python |
|
#!pip install transformers |
|
#!pip install torch |
|
#!pip install tokenizers |
|
|
|
import torch |
|
import transformers |
|
from transformers import RobertaTokenizer, RobertaTokenizerFast |
|
|
|
tokenizer = RobertaTokenizerFast.from_pretrained("ehsanaghaei/SecureBERT_Plus") |
|
model = transformers.RobertaForMaskedLM.from_pretrained("ehsanaghaei/SecureBERT_Plus") |
|
|
|
def predict_mask(sent, tokenizer, model, topk =10, print_results = True): |
|
token_ids = tokenizer.encode(sent, return_tensors='pt') |
|
masked_position = (token_ids.squeeze() == tokenizer.mask_token_id).nonzero() |
|
masked_pos = [mask.item() for mask in masked_position] |
|
words = [] |
|
with torch.no_grad(): |
|
output = model(token_ids) |
|
|
|
last_hidden_state = output[0].squeeze() |
|
|
|
list_of_list = [] |
|
for index, mask_index in enumerate(masked_pos): |
|
mask_hidden_state = last_hidden_state[mask_index] |
|
idx = torch.topk(mask_hidden_state, k=topk, dim=0)[1] |
|
words = [tokenizer.decode(i.item()).strip() for i in idx] |
|
words = [w.replace(' ','') for w in words] |
|
list_of_list.append(words) |
|
if print_results: |
|
print("Mask ", "Predictions: ", words) |
|
|
|
best_guess = "" |
|
for j in list_of_list: |
|
best_guess = best_guess + "," + j[0] |
|
|
|
return words |
|
|
|
|
|
while True: |
|
sent = input("Text here: \t") |
|
print("SecureBERT: ") |
|
predict_mask(sent, tokenizer, model) |
|
|
|
print("===========================\n") |
|
