Agentic RAG Chronicles

Introducing: The Agentic RAG Chronicles (Blog Series) Last year I chronicled several RAG Demos with the idea I would have a documented place to return to when I was looking for specify RAG features. Having those demos documented and all the reference links in one location really was useful for me - so I am going to do the same thing this year, but with Agentic RAG components. Agentic RAG Last year when I was learning RAG, that technique became known as Standard RAG or Semantic RAG. At its core, it’s a system that uses semantic search—understanding meaning rather than just matching keywords—to find relevant information, then feeds that information to an LLM to answer a user’s question. When you first build one of these systems, the results feel almost magical. But it …

Virtual Boston Azure AI - Microsoft Build Recap

Last night Bill, Udai, Veronika and I gave our top picks from Microsoft Build at the Virtual Boston Azure AI meetup. In order to not overlap topics, we each picked areas to cover - mine was Copilot and Copilot Studio. My picks: Copilot Wave 2 Spring release features – this was announced in April but still hasn’t landed for us. You’ll know when this lands due to the look of Copilot changing. The navigation will be on the left side of the screen with the new release (instead of the right where it is now). Publish custom agents to SharePoint sites – This adds SharePoint as a channel to push a Copilot Studio agent to. Additional maker controls for knowledge (Copilot Studio) – This is several things together: Ability to upload related files into a file collection Ability to change settings on …

eShopSupport Series: EvaluationTests Project

This is the seventh part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. NOTE: This entry will make the most sense to you if you’ve first read eShopSupport: Evaluator Project EvaluationTests Project The EvaluationTests project is a recently added xUnit Test Project that uses the new Microsoft.Extensions.AI.Evaluation packages highlighted in this blog: Evaluate the quality of your AI applications with ease. I think the idea is to replace the Evaluator project but, as is, it doesn’t run all 500 evaluation questions in the dev folder (which is good since it would not be cheap to do unless you are running locally). The good news is: the EvaluationTests project is a good example of how to use the new Microsoft.Extensions.AI.Evaluation …

Techbash 2024

This week I presented at the TechBash conference in Pocono Manor, PA. All the resources for the conference are available on the TechBash GitHub repo. Below are links to my presentations specifically.

eShopSupport Series: Evaluator Project

This is the third part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. Evaluator Project The Evaluator project is a console application used to evaluate the chat portion of the application provided by the AssistantApi in the Backend project. The Evaluator application uses the questions in the evalquestions.json file to test the assistant API and scores the results it returns against the answers in that JSON file. This gives you the ability to measure the quality of the chat functionality - which is an important thing to do when you are building application functionality that depends on an LLM. The Evaluator project is located in in the src folder: In this entry I’ll cover the details of how the Evaluator application works, a few things I …
