Sessions
Building Streamlit apps is easy for Data Scientists - but when it’s time to deploy them to the cloud, challenges like slow model loading, scalability, and security can become major hurdles. This talk bridges two perspectives: the Data Scientist who builds the app and the MLOps engineer who deploys it. We'll dive into optimizing model loading from Hugging Face Hub, implementing features like autoscaling and authentication, and securing your app against potential threats. By the end of this talk, you’ll be ready to design Streamlit apps that are functional and deployment-ready for the cloud.
Retrieval Augmented Generation (RAG) is a powerful technique for searching across unstructured documents, but it often falls short when the task demands an understanding of intricate relationships between entities. GraphRAG addresses this by leveraging knowledge graphs to capture these relationships, but it struggles with scalability and handling diverse unstructured formats. In this talk, we’ll explore how HybridRAG combines the strengths of both approaches - RAG for scalable unstructured data retrieval and GraphRAG for semantic richness- to deliver accurate and contextually relevant answers. We’ll dive into its application, challenges, and the significant improvements it offers for question-answering systems across various domains.
