embedding the German version of the AI Act using our advanced embedding tool and MTEB. We'll then use these embeddings in a local chat application as a retriever/context. ### Step 1: Prepare the Document 📄 1. Download the German version of the AI Act (let's call it `ai_act_de.txt`). 2. Place the file in your project directory. ### Step 2: Set Up the Embedding Tool 🛠️ 1. Open the Embedding Comparison Tool. 2. Navigate to the new "Automation" tab. ### Step 3: Configure the Automated Test 🔧 In the "Use Case" tab, set up the following configuration: ```markdown - File: ai_act_de.txt - Query: "Wie definiert das Gesetz KI-Systeme?" - Model Types: ✅ HuggingFace, ✅ Sentence Transformers - Model Names: paraphrase-multilingual-MiniLM-L12-v2, distiluse-base-multilingual-cased-v2 - Split Strategies: ✅ recursive, ✅ token - Chunk Sizes: 256, 512, 1024 - Overlap Sizes: 32, 64, 128 - Vector Store Types: ✅ FAISS - Search Types: ✅ similarity, ✅ mmr - Top K Values: 3, 5, 7 - Test Vocabulary Optimization: ✅ - Test Query Optimization: ✅ - Test Reranking: ✅ ``` ### Step 4: Run the Automated Test 🏃‍♂️ Click the "Run Automated Tests" button and wait for the results. ### Step 5: Analyze the Results 📊 Let's say we got the following simulated results: ```markdown Best Model: Sentence Transformers - paraphrase-multilingual-MiniLM-L12-v2 Best Settings: - Split Strategy: recursive - Chunk Size: 512 - Overlap Size: 64 - Vector Store Type: FAISS - Search Type: mmr - Top K: 5 - Optimize Vocabulary: True - Use Query Optimization: True - Use Reranking: True Performance Summary: - Search Time: 0.15s - Result Diversity: 0.82 - Rank Correlation: 0.91 - Silhouette Score: 0.76 ``` ### Step 6: Understand the Results 🧠 1. **Model**: The Sentence Transformers model performed better, likely due to its multilingual capabilities and fine-tuning for paraphrasing tasks. 2. **Split Strategy**: Recursive splitting worked best, probably because it respects the document's structure better than fixed-length token splitting. 3. **Chunk Size**: 512 tokens provide a good balance between context and specificity. 4. **Search Type**: MMR (Maximum Marginal Relevance) outperformed simple similarity search, likely due to its ability to balance relevance and diversity in results. 5. **Optimizations**: All optimizations (vocabulary, query, and reranking) proved beneficial, indicating that the extra processing time is worth the improved results. ### Step 7: Implement in Local Chat 💬 Now that we have the optimal settings, let's implement this in a local chat application: 1. Use the `paraphrase-multilingual-MiniLM-L12-v2` model for embeddings. 2. Set up a FAISS vector store with the embedded chunks. 3. Implement MMR search with a top-k of 5. 4. Include the optimization steps in your pipeline. ### Step 8: Test the Implementation 🧪 Create a simple chat interface and test with various queries about the AI Act. For example: User: "Was sind die Hauptziele des KI-Gesetzes?" """ tutorial_md = """ # Advanced Embedding Comparison Tool Tutorial Welcome to the **Advanced Embedding Comparison Tool**! This comprehensive guide will help you understand and utilize the tool's features to optimize your **Retrieval-Augmented Generation (RAG)** systems. ## Table of Contents 1. [Introduction to RAG](#introduction-to-rag) 2. [Key Components of RAG](#key-components-of-rag) 3. [Impact of Parameter Changes](#impact-of-parameter-changes) 4. [Advanced Features](#advanced-features) 5. [Using the Embedding Comparison Tool](#using-the-embedding-comparison-tool) 6. [Automated Testing and Analysis](#automated-testing-and-analysis) 7. [Mathematical Concepts and Metrics](#mathematical-concepts-and-metrics) 8. [Code Examples](#code-examples) 9. [Best Practices and Tips](#best-practices-and-tips) 10. [Resources and Further Reading](#resources-and-further-reading) --- ## Introduction to RAG **Retrieval-Augmented Generation (RAG)** is a powerful technique that combines the strengths of large language models (LLMs) with the ability to access and use external knowledge. RAG is particularly useful for: - Providing up-to-date information - Answering questions based on specific documents or data sources - Reducing hallucinations in AI responses - Customizing AI outputs for specific domains or use cases RAG is ideal for applications requiring accurate, context-specific information retrieval combined with natural language generation, such as chatbots, question-answering systems, and document analysis tools. --- ## Key Components of RAG ### 1. Document Loading Ingests documents from various sources (PDFs, web pages, databases, etc.) into a format that can be processed by the RAG system. The tool supports multiple file formats, including PDF, DOCX, and TXT. ### 2. Document Splitting Splits large documents into smaller chunks for more efficient processing and retrieval. Available strategies include: - **Token-based splitting** - **Recursive splitting** ### 3. Vector Store and Embeddings Embeddings are dense vector representations of text that capture semantic meaning. The tool supports multiple embedding models and vector stores: - **Embedding models**: HuggingFace, OpenAI, Cohere, and custom models. - **Vector stores**: FAISS and Chroma. ### 4. Retrieval Finds the most relevant documents or chunks based on a query. Available retrieval methods include: - **Similarity search** - **Maximum Marginal Relevance (MMR)** - **Custom search methods** --- ## Impact of Parameter Changes Understanding how different parameters affect your RAG system is crucial for optimization: - **Chunk Size**: Larger chunks provide more context but may reduce precision. Smaller chunks increase precision but may lose context. - **Overlap**: More overlap helps maintain context between chunks but increases computational load. - **Embedding Model**: Performance varies across languages and domains. - **Vector Store**: Affects query speed and the types of searches. - **Retrieval Method**: Influences the diversity and relevance of retrieved documents. --- ## Advanced Features ### 1. Custom Tokenization Upload a custom tokenizer file and specify the tokenizer model, vocabulary size, and special tokens for domain or language-specific tokenization. ### 2. Query Optimization Improve search results by generating multiple variations of the input query using a language model to capture different phrasings. ### 3. Reranking Further refine search results by using a separate model to re-score and reorder the initial retrieval results. ### 4. Phonetic Matching For languages like German, phonetic matching with adjustable weighting is available. ### 5. Vocabulary Optimization Optimize vocabulary for domain-specific applications during the embedding process. --- ## Using the Embedding Comparison Tool The tool is divided into several tabs for ease of use: ### Simple Tab 1. **File Upload**: Upload a file (PDF, DOCX, or TXT) or use files from the `./files` directory. 2. **Search Query**: Enter the search query. 3. **Embedding Models**: Select one or more embedding models to compare. 4. **Top K**: Set the number of top results to retrieve (1-10). ### Advanced Tab 5. **Custom Embedding Model**: Specify a custom embedding model. 6. **Split Strategy**: Choose between 'token' and 'recursive' splitting. 7. **Chunk Size**: Set chunk size (100-1000). 8. **Overlap Size**: Set overlap between chunks (0-100). 9. **Custom Split Separators**: Enter custom separators for text splitting. 10. **Vector Store Type**: Choose between FAISS and Chroma. 11. **Search Type**: Select 'similarity', 'mmr', or 'custom'. 12. **Language**: Specify the document's primary language. ### Optional Tab 13. **Text Preprocessing**: Toggle text preprocessing. 14. **Vocabulary Optimization**: Enable vocabulary optimization. 15. **Phonetic Matching**: Enable phonetic matching and set its weight. 16. **Custom Tokenizer**: Upload a custom tokenizer and specify parameters. 17. **Query Optimization**: Enable query optimization and specify the model. 18. **Reranking**: Enable result reranking. --- ## Automated Testing and Analysis The **Automation tab** allows you to run comprehensive tests across multiple configurations: 1. Set up test parameters like model types, split strategies, chunk sizes, etc. 2. Click "Run Automated Tests." 3. View results, statistics, and recommendations to find optimal configurations for your use case. --- ## Mathematical Concepts and Metrics ### Cosine Similarity Measures the cosine of the angle between two vectors, used in similarity search: $$\text{cosine similarity} = \frac{\mathbf{A} \cdot \mathbf{B}}{\|\mathbf{A}\| \|\mathbf{B}\|}$$ ### Maximum Marginal Relevance (MMR) Balances relevance and diversity in search results: $$\text{MMR} = \arg\max_{D_i \in R \setminus S} [\lambda \text{Sim}_1(D_i, Q) - (1-\lambda) \max_{D_j \in S} \text{Sim}_2(D_i, D_j)]$$ ### Silhouette Score Measures how well an object fits within its own cluster compared to others. Scores range from -1 to 1, where higher values indicate better-defined clusters. --- ## Code Examples ### Custom Tokenization ```python def create_custom_tokenizer(file_path, model_type='WordLevel', vocab_size=10000, special_tokens=None): with open(file_path, 'r', encoding='utf-8') as f: text = f.read() tokenizer = Tokenizer(models.WordLevel(unk_token="[UNK]")) if model_type == 'WordLevel' else Tokenizer(models.BPE(unk_token="[UNK]")) tokenizer.pre_tokenizer = Whitespace() trainer = trainers.WordLevelTrainer(special_tokens=special_tokens or ["[UNK]", "[CLS]", "[SEP]", "[PAD]", "[MASK]"], vocab_size=vocab_size) tokenizer.train_from_iterator([text], trainer) return tokenizer ```` ### Query Optimization ```python def optimize_query(query, llm): multi_query_retriever = MultiQueryRetriever.from_llm( retriever=get_retriever(vector_store, search_type, search_kwargs), llm=llm ) optimized_queries = multi_query_retriever.generate_queries(query) return optimized_queries ```` ### Reranking ```python def rerank_results(results, query, reranker): reranked_results = reranker.rerank(query, [doc.page_content for doc in results]) return reranked_results ```` ### Best Practices and Tips - Start Simple: Begin with basic configurations, then gradually add complexity. - Benchmark: Use automated testing to benchmark different setups. - Domain-Specific Tuning: Consider custom tokenizers and embeddings for specialized domains. - Balance Performance and Cost: Use advanced features like query optimization and reranking judiciously. - Iterate: Optimization is an iterative process—refine your approach based on tool insights. ## Useful Resources and Links Here are some valuable resources to help you better understand and work with embeddings, retrieval systems, and natural language processing: ### Embeddings and Vector Databases - [Understanding Embeddings](https://www.tensorflow.org/text/guide/word_embeddings): A guide by TensorFlow on word embeddings - [FAISS: A Library for Efficient Similarity Search](https://github.com/facebookresearch/faiss): Facebook AI's vector similarity search library - [Chroma: The AI-native open-source embedding database](https://www.trychroma.com/): An embedding database designed for AI applications ### Natural Language Processing - [NLTK (Natural Language Toolkit)](https://www.nltk.org/): A leading platform for building Python programs to work with human language data - [spaCy](https://spacy.io/): Industrial-strength Natural Language Processing in Python - [Hugging Face Transformers](https://huggingface.co/transformers/): State-of-the-art Natural Language Processing for PyTorch and TensorFlow 2.0 ### Retrieval-Augmented Generation (RAG) - [LangChain](https://python.langchain.com/docs/get_started/introduction): A framework for developing applications powered by language models - [OpenAI's RAG Tutorial](https://platform.openai.com/docs/tutorials/web-qa-embeddings): A guide on building a QA system with embeddings ### German Language Processing - [Kölner Phonetik](https://en.wikipedia.org/wiki/Cologne_phonetics): Information about the Kölner Phonetik algorithm - [German NLP Resources](https://github.com/adbar/German-NLP): A curated list of open-access resources for German NLP ### Benchmarks and Evaluation - [MTEB Leaderboard](https://huggingface.co/spaces/mteb/leaderboard): Massive Text Embedding Benchmark leaderboard - [GLUE Benchmark](https://gluebenchmark.com/): General Language Understanding Evaluation benchmark ### Tools and Libraries - [Gensim](https://radimrehurek.com/gensim/): Topic modelling for humans - [Sentence-Transformers](https://www.sbert.net/): A Python framework for state-of-the-art sentence, text and image embeddings ### Support me - [Visual Crew Builder](https://visual-crew.builder.ai/): Tool for create AI systems, workflows and api.
