#jupyter_notebook Retrieval Augmented Generation (RAG) helps large language models (LLMs) answer questions using up-to-date or private information by connecting them to external data sources, unlike fine-tuning which retrains the model on specific data. RAG is useful when you need current, dynamic information without costly retraining, making it ideal for tasks like customer support or knowledge management. Fine-tuning is better for deep expertise in a specialized field but requires more data and effort. Using RAG lets you get accurate, relevant answers quickly by combining the model’s language skills with fresh, specific data, improving usefulness and reliability. https://github.com/langchain-ai/rag-from-scratch

#python#ai#llm#rag#reasoning#retrieval PageIndex is an advanced AI tool that helps you find the most relevant information in long professional documents by thinking and reasoning like a human expert, rather than just matching keywords. It organizes documents into a clear tree structure, similar to a table of contents, and searches through this structure to give precise, trustworthy answers with exact page references. This method avoids the common problems of traditional vector-based search, making it ideal for complex reports, legal texts, or financial filings. You can use it easily via cloud services or run it locally, improving your ability to analyze and understand large documents quickly and accurately. https://github.com/VectifyAI/PageIndex

⚡️ Omni-Embed-Nemotron - новая единая модель от NVIDIA для поиска по тексту, изображениям, аудио и видео Модель обучена на разнообразных мультимодальных данных и может объединять разные типы входных сигналов в общее векторное представление. - Поддержка всех типов данных: текст, изображение, аудио, видео. - Основана на архитектуре Qwen Omni (Thinker-модуль, без генерации текста). - Контекст - до 32 768 токенов, размер embedding — 2048. - Оптимизирована под GPU, поддерживает FlashAttention 2. Это делает её идеальной для: - кросс-модального поиска (поиск текста по видео или изображению); - улучшения RAG-проектов; - систем мультимодального понимания контента. Просто, быстро и эффективно - всё в одном открытом решении. 🌐 Открытая модель: https://huggingface.co/nvidia/omni-embed-nemotron-3b @ai_machinelearning_big_data #crossmodal#retrieval#openAI#NVIDIA#OmniEmbed#multimodal#AIModels#OpenSource#Search#UnifiedEmbedding
