Notable Quotes

  • "Fly gives you a lot of flexibility, like a lot of flexibility on multiple fronts. It allows developers to quickly adapt their applications to different infrastructures." [00:56]

  • "With Tigris, the moment you upload something, it's available in that region instantly. It's incredibly easy to use and set up, ensuring that the work is both efficient and effective." [02:00]

  • "When you look at the interconnections in a graph structure, you realize it represents data that's highly interconnected, which is crucial for understanding complex relationships." [06:30]

  • "Graph databases can be thought of as a specialized database that allows you to scalably manage and query data that's organized as a graph. This is crucial in expressing complex relationships intelligently and effectively." [00:00]

  • "The reason why retrieval-augmented generation (RAG) has gained traction is not because retrieval techniques are new, but rather because the generation capabilities are revolutionary, enabled by advancements in generative language models." [00:00]

  • "Now on paper, this naive approach to doing RAG is great, but it quickly became obvious that this has limitations." [25:00]

  • "The first limitation is that the dense embeddings are typically done at the sentence level, which often doesn't capture the intended context." [25:40]

  • "And this is how you combine the sparse and dense vectors into what you call a hybrid search." [14:50]

  • "A poor retrieval with garbage results is going to result in a garbage output from the generation model, emphasizing how the quality of input drastically impacts generated results." [00:57]

  • "We need a high quality graph. It's paramount because, as we know, in any RAG system, the quality of your retrieval greatly impacts the quality of the generation downstream." [01:04]

  • "The idea here is these models are, I guess, more controllable in what you can output from them. It's not like an LLM where you just don't know what you're going to get." [02:00]

  • "So as this capability keeps evolving and LLMs keep morphing into whatever else they become, there's no guarantee that the kinds of tasks being done today using custom models, machine learning models, won't be done by an LLM." [49:00]

  • "What I'm particularly excited about in the next few years is everyone's been talking about agentic systems. And if you look at the pivots that all these framework companies have had in the last year, like Bankchain, LLM Index, they're heavily trying to push this field forward in terms of how agents can help build, I guess, more capable systems." [49:30]

  • "I don't see that happening in the next few years. But that being said, the field of graph, or you could say knowledge graphs and their role in symbolic systems, they've been around. It's been around for so long." [53:00]

Controversial Points

  • The idea that RAG emerged notably after the introduction of LLMs, with some arguing about the timeline and significance of these advancements.(00:00)
  • One controversial idea is that while GraphWrag aims to reduce hallucinations in LLM outputs, it does not completely eliminate them.(27:51)
  • There are many ways you can combine vector search and graph traversals to improve retrieval accuracy, indicating no single correct approach but a variety of methods to explore.(01:28)
  • The idea that LLMs will replace certain traditional machine learning applications is debated, with opinions on whether these models can adapt to varying tasks as extensively as custom solutions.(49:00)
