[sentence-transformers](https://www.SBERT.net) model finetuned from [huggingface/CodeBERTa-small-v1](https://huggingface.co/huggingface/CodeBERTa-small-v1). 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:** [huggingface/CodeBERTa-small-v1](https://huggingface.co/huggingface/CodeBERTa-small-v1) - **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, 'architecture': '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-CODEBERTA-CONTRASTIVE-PAIRS-E1-B16-LR2e-05-Split0.1") # Run inference sentences = [ '\n\nimport java.io.*;\nimport java.net.*;\nimport java.misc.BASE64Encoder;\n\npublic class Dictionary\n{\n public Dictionary()\n {}\n\n public boolean fetchURL(String urlString,String username,String password)\n {\n StringWriter sw= new StringWriter();\n PrintWriter pw = new PrintWriter();\n try{\n URL url=new URL(urlString); \n String userPwd= username+":"+password;\n\n \n \n \n \n\n BASE64Encoder encoder = new BASE64Encoder();\n String encodedStr = encoder.encode (userPwd.getBytes());\n System.out.println("Original String = " + userPwd);\n\t System.out.println("Encoded String = " + encodedStr);\n\n HttpURLConnection huc=(HttpURLConnection) url.openConnection(); \n huc.setRequestProperty( "Authorization"," "+encodedStr); \n InputStream content = (InputStream)huc.getInputStream();\n BufferedReader in =\n new BufferedReader (new InputStreamReader (content));\n String line;\n while ((line = in.readLine()) != null) {\n pw.println (line);\n System.out.println("");\n System.out.println(sw.toString());\n }return true;\n } catch (MalformedURLException e) {\n pw.println ("Invalid URL");\n return false;\n } catch (IOException e) {\n pw.println ("Error URL");\n return false;\n }\n\n }\n\n public void getPassword()\n {\n String dictionary="words";\n String urlString="http://sec-crack.cs.rmit.edu./SEC/2/";\n String login="";\n String pwd=" ";\n\n try\n {\n BufferedReader inputStream=new BufferedReader(new FileReader(dictionary));\n startTime=System.currentTimeMillis();\n while (pwd!=null)\n {\n pwd=inputStream.readLine();\n if(this.fetchURL(urlString,login,pwd))\n {\n finishTime=System.currentTimeMillis();\n System.out.println("Finally I gotta it, password is : "+pwd);\n System.out.println("The time for cracking password is: "+(finishTime-startTime) + " milliseconds");\n System.exit(1);\n } \n\n }\n inputStream.close();\n }\n catch(FileNotFoundException e)\n {\n System.out.println("Dictionary not found.");\n }\n catch(IOException e)\n {\n System.out.println("Error dictionary");\n }\n }\n\n public static void main(String[] arguments)\n {\n BruteForce bf=new BruteForce();\n bf.getPassword();\n } \n}', '\n\nimport java.io.*;\nimport java.*;\n\npublic class BruteForce \n{\n public static void main(String args[]) \n {\n String s = null;\n String basic_url = "http://sec-crack.cs.rmit.edu./SEC/2/";\n\n \n String alphabets = new String("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");\n \n String password = null;\n int len = 0;\n int num_tries = 0;\n\n len = alphabets.length();\n \n \n for (int i=0; i 1) {\n\n }\n } else {\n \n \n System.out.println ("What the?...
