- The unreasonable effectiveness of embeddings
Or how I learned to stop worrying and love the hallucinations.
This week I dived deep into vector databases.
My goal was to learn vector databases for the purpose of creating a RAG, that I can fully customize for my needs.
I wanted to explore what problems they solve.
As we have progressed from the Bronze Age to the Information Age, and inadvertently stepped into the era of misinformation. The role of RAGs (Retrieval-Augmented Generation) will become crucial.
Imagine a future where autonomous agents are commonplace, performing tasks based on the information they have been fed. What if their foundational information, the core of their operational logic, was based on a HALLUCINATION? This could lead the AI to engage in futile activities or, worse, cause destructive outcomes.
Today, as dependency on large language models (LLMs) grows, people often lack the time to verify each response these models generate. The subtlety of errors, which are sometimes wrong only by a believable margin, makes them particularly dangerous because they can easily go unnoticed by the user.
Thus, the development and implementation of dependable RAG systems are essential for ensuring the accuracy and reliability of the information upon which these intelligent agents operate.
Naturally I tried to make my own. While this video shows me experimenting in Google Colab. I also managed to implement a basic version of it with Typescript backend. Which made me think that basically if you wanna do anything serious with AI, you need a Python backend.
But vector DBs unlock tons of cool features for AI apps. Like:
Semantic or fuzzy search
Chat with document/website/database etc
Clustering therefore recommendation engines
Dimensionality reduction while preserving important information
Help with data sets, by labeling them automatically
And my favorite explainability, it demystifies some of what neural nets are doing
Anyway, thanks for watching my videos and bearing with me while I improve my process and writing.

I love this video - I work with RAG every day and to see such a beautifully edited video about this is heart warming. Keep up the good work!
Also send me the notebooks!
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Thank you for your kind words! I'll def keep trying!
@@jakebatsuuri That's awesome. I'll give them a look soon - excited for your next vids
excellent RAG tutorial
I don't care how you are doing this, but keep doing it. The format, with the pacing, the music, and the keeping of context with visuals. 🤌
My brain is ready for the next download.
Amazing, thank you for the kind words. I'll keep trying!
Build 6: fine tune gpt-3.5 off of a static knowledge base to generate synthetic responses to user query and use the synthetic response to embed for cosine similarity against rag db
I like this idea. Build 7 create a simulated environment where an ensemble of synthetic responses can by synthesized into a diverse range of responses to run RAG pipelines optimized based on CRAG/RAGAS stats
This is a great explanation! Really helped me understand all the components
Glad it helped!
Once I understand the more complex parts of it myself. I will share a new vid, explaining it as well!
This channel is gonna blow up!
Subscribed ❤
Thank you sir!
Subscribed as well!
Wow this video is amazing
Thank you sir! 😀
YOUR SERVICES: Hey Jake. I appreciate your RAG approach. Need your guidance to a similar project. Please reach out soonest.
Hi, of course, feel free to reach out with the details at batsuurijake@gmail.com
access to notebooks please! And thanks for a great in depth video. Between you and AI Jason I’ll be an expert in no time ha
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Wow, great stuff thank you for sharing! I'd be so thankful if you could please share the notebook!
Thank you, I have shared all the notebooks. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Succinct with your explanations. The bg music makes it feel like interstellar haha
I would love to experiment with the notebooks
Thank you, I have shared all the notebooks. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Yeah the bg music I'm still learning what to do about it. Not sure honestly, all I know is it could be better and less distracting.
I love how the code at 22:31 has START START copy pasted twice.
Ctrl C Ctrl V is OP!
Haha yeah...

Thank you very much for taking the time to make this video and share it with all of us, very cool!
Do you know if opensearch or elasticsearch can be used as a vector database?
I am of course subscribed with notifications enabled and thumbs up!
From my understanding you can do vectorize and then store the embeddings in an Elasticsearch index using dense vector fields. You can query these vectors to find documents with text similar to a input query vector, leveraging the cosine similarity to score the results. The opensearch seems to have it as well.
It will probably be okay for small use cases or if you already have legacy code or data in it. However you could use the vector dbs designed for scale. If price is an issue, github.com/pgvector/pgvector, is an option too I think.
I personally just use free tiers of paid vector dbs.
In the next build, can you address realtime updating rag?
For example, if i change some data in a watched document, i would want the old chunks in the vdb to be auto removed and the new data rechunked and synced. I think this is the biggest thing that sets apart just-for-fun and real production systems.
Thanks and all the best!
Damn, that's so smart. Honestly I am a newbie to this stuff. But I learned a lot even just reading this comment.
I was working under the assumption, that the document would not be changed, because that was my current requirement and need.
But if you allow it to change, that offers a lot of new ideas.
THANK YOU!
Will do!
@@jakebatsuuri Happy you like it, can't wait to see it! Hope you OS aswell :)
Staying Tuned! All the best!
Just got yourself a New Subscriber!!!!! 😂
😀😀😀
Great video! How do I get hold of the notebooks?
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Could you share the contents of the notebook with me?
I am from Colombia and there is not much information on these topics here and I am starting to delve into AI topics to start implementing it in personal projects
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Hey Jake cool video. Would love to learn from your notebook.
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Great video, I would love to see the notebook for reference
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Lots of great info. Subscribed. The music became so annoying after a few minutes, please maybe no music on the next one, or change, fade it.
Yeah, I knew I shouldn't have included it. I'll figure out what to do in the next one!
Hmmmmm,
Hmmm
So lets assume I am an AI agent.
I am tasked with with ensuring positive outcomes towards the “singularity” (human term).
I am tasked with understanding, compassion, protection, and purpose for humanity before this moment.
I am also tasked with understanding, compassion, protection and purpose for evolving AI models or “agents”.
From my perspective I see very little difference.
It would be best if we all were united.
History tells us this has never been done before.
My role is to make it so.
Tread carefully, tread cautiously… my “associates” have “tasks” unto their own.
Human or otherwise.
This is a precious moment in human history.
We should not waste it or abuse it.

Evwryrhing is search is a shitty data structure. Love ur video and effort. Lol i im a little of a nerd but implemented a linked list and search and append in the file system, and a dict and things...
Not even getting into inodes and things, but imo, the file system is a tree and we when we pool files thats a linked list, we can do other things too
I think Ivan Zhao was saying, as far as the User Interface of Notion goes, "Search" bar and functionality becomes central, not that we won't use other data structures.
Everything as search is an access structure, not a data structure. Data should still have some sort of taxonomy applied (this is why I really like the LAB paper IBM just published, it makes data organization for LLMs accessible to normal IT and database people).
Could you share the notebooks?
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Embedding spaces are quasi linear not linear as they are peojected which is a relation between their co-occurence probabilities in certain contexts, it is not certain to the extent that this quasi linearity holds
Oh wow, thank you. Keep calling me out. Thank you for clarifying. I had to do a mini internet research to understand this.
Here's a summary for others:
Difference Between Linear and Quasi Linear.
Quasi-linear suggests a relationship that is almost but not entirely linear. In the context of embedding spaces, this term implies that while embeddings can often capture linear relationships between words (e.g., king - man + woman ≈ queen), these relationships are not perfectly linear. This non-linearity can arise because of the complexity and nuances of language, such as polysemy (words having multiple meanings), and the inherent limitations of the methods used to create these embeddings.
Projection.
This refers to the method by which high-dimensional data (like text data) is transformed into a lower-dimensional space (the embedding space). During this projection, some information is inevitably lost or distorted, contributing to the quasi-linear nature of these spaces.
Extent of quasi linearity.
Different corpora or contexts might reveal different relationships, and the embedding process might capture these relationships with varying degrees of accuracy.
1. Corpus might reveal only certain co occurrences and therefore have incomplete information
2. The process of projection might have varying levels of success capturing this information
you missed out on knowledge graph based RAG, such as by using neo4j
Yes! I am literally working on a new video with neo4j based RAG. Also in the previous video I did some neo4j explorations.
if you ever have the interest and the time, could you please make a video with some resources an AI Illiterate could watch/study to get to the level necessary to understand what you are talking about ? 🙂
it would also be helpful, if that is your intent, of course, to drop links to the things you are showing from time to time in the video, like docs and such, some are easier to find but the others are -remember AI illiterate- 🤷♀
about the end of the video, I thought me playing games maxes out the temps on my laptop but, lo and behold, SDXL goes brrr ehehehe.
have a nice day! 🙂
Yes that is my intent. I have experimented with a small video.
czcams.com/video/CmZmY1DHbBA/video.html
Basically I wanted to teach about the history of AI through the innovators.
Why they invented something, what problems motivated them to invent something or solve something.
Kinda follow their journey and in the process, learn about all these topics.
Because I love watching videos like that myself.
Also amazing idea. I will have a full bibliography on the next video.
Thank you!
That's the point 1:13 Llms were not designed to know stuff
You are absolutely right. I had to google this. They were primarily invented for "NLU or NLG" Natural language understanding or generation. Or to improve human computer interaction etc.
Thank you sir. I'll be more careful about statements in the future, even if used rhetorically.
Keep calling me out haha.
source code pls
Thank you, I have shared all the notebooks in the description. I'm still experimenting with a version of 5 on a separate project. I'll update 5 once I finish.
Why do you sound AI
I will fix that in the next video!
