Very well explained!!! Thank you for your explanation of this. I’m so tired of 45 minute UA-cam videos with a college educated professional trying to explain ML topics. If you can’t explain a topic in your own language in 10 minutes or less than you have failed to either understand it yourself or communicate effectively.
Einstein said, "If you can't explain it simply, you don't understand it well enough." And you explained it beautifuly in most simple and easy to understand way 👏👏. Thank you

That's a really great explanation of RAG in terms most people will understand. I was also sufficiently fascinated by how the writing on glass was done to go hunt down the answer from other comments!
Wow, I opened youtube coming from the ibm blog just to leave a comment. Clearly explained, very good example, and well presented as well!! :) Thank you
The explanation was spot on! IBM is the go to platform to learn about new technology with their high quality content explained and illustrated with so much simplicity.
@@aykoch she is right handed. when she writes, the arm moves away from the body. left hand arm would move toward the body. because the video is flipped, it's a bit of a mind trick to see it.
@@jsonbourne8122 Nice attention to detail as they made sure the outfit was symmetrical without any logos and had a ring on each hand's ring finger, making it harder to tell it was flipped.
I believe the video is slightly inaccurate. As one of the commenters mentioned, the LLM is frozen and the act of interfacing with external sources and vector datastores is not carried out by the LLM. The following is the actual flow: Step 1: User makes a prompt Step 2: Prompt is converted to a vector embedding Step 3: Nearby documents in vector space are selected Step 4: Prompt is sent along with selected documents as context Step 5: LLM responds with given context Please correct me if I'm wrong.
I’m not sure. Looking at OpenAI documentation on RAG, they have a similar flow as demonstrated in this video. I think the retrieval of external data is considered to be part of the LLM (at least per OpenAI)
I do not think retrieval is part of LLM. LLM is the best model at the end of convergence after training. It can't be modified rather after LLM response you can always use that info for next flow of retrieval
We also need the models to cross check their own answers with the sources of information before printing out the answer to the user. There is no self control today. Models just say things. "I don't know" is actually a perfectly fine answer sometimes!
Just simply write on a glass board ,record it from the other side and laterally flip the image! Simple aa that.. and pls dont distract people from the contents being lectured by thinkin about the process behind the rec🤣
The interesting part is not retrieval from the internet, but retrieval from long term memory, and with a stated objective that builds on such long term memory, and continually gives it "maintenance" so it's efficient and effective to answer. LLMs are awesome because even though there are many challenges ahead, they sort of give us a hint of what's possible, without them it would be hard to have the motivation to follow the road
The video is short and consice yet the delivery is very elegant. She might be the best instructor that have teached me. Any idea how the video was created?
I have few questions here @ (1) When I prompt and it is not present in context store, shall I get generated text from LLM? 2. when I prompt and a match with embeddings of context store, shall I get content generated from both LLM and Context store? 3. How to enforce RAG framework in Langchain? Appreciate answers
tokens as a [word] is what I'm working on right now (solo, self learning LLM techniques), this video helped me realize how the model doesn't know what it's outputting obviously, but AI-AI is different, so building tokens that have dimensional vectors that process in a separate model, can be used for explainable AI.
meaning a separate model processes the response itself, meta, it's for building evolution learning. AI-AI machine learning, you need a way to configure in between the iterations.
Nicely explained. My questions/doubts? 1. Doesn't this raise questions about the process of building and testing LLMs? 2. In such scenarios will the test and training data used be considered authentic and not "limited and biased"? 3. Is there a process/standard on how often the "primary source data" should be updated?
Thanks. Great video. I've had too many conversations where Chatgpt has apparently just made stuff up. I know that's not what happens really, but it seems like it and it still makes untrue statements. I'm glad researchers are working to improve things.
I spent all of the 1st watch talking while a friend watched it aswell trying to figure out is she is a robot because of the backwards writing. Good and fast info the 2nd watch. Great job
Great lessons! Nice of you to step out 🙃 and make such engaging and educative content This is a very useful in helping us in critical thinking. Thank you for sharing this video. 👍 Current ai models may impose neurotypical norms and expectations based on current data trained on . 🤔 Curious to see more on how IBM approach the challenges and limitations of Ai
Less Helium! How does this system resolve conflicting answers from the datastore and generative process? Does the datastore answer always take precedence - and if so - is there a logic or reasoning layer that checks how reliable and up-to-date the datastore is and its reliability index?
So the question I have here is when I have an answer from my LLM but not the Rag data, what is the response to the user? "I don't know" or the LLM response that may be out of date or without a reliable source? Looks like a question for an LLM :)
Outstanding explanation. Its very easy to underatand. I like the way the video is made with presenter writing to the blackboard . I want to know what SOFTWARE/TOOL is used to make this video/presentation. Its really cool.
Hi, thanks for your share and I have a question regarding the RAG framework. Is the content of the answers solely retrieved from documents, or does the LLM integrate the retrieved content with its own knowledge before providing a response?
Very well explained.❤ But what happens if RAG and LLM trained data has conflict. in this case LLM knows answer as Jupiter and rag content store is saying answer is Saturn. Is it that RAG always gets higher weightage?
This is brilliant and concise, helped make sense of a complex subject.. Can this be implemented in a small environment with limited computing? Such that the retriever only has access to a closed data source
This lecturer should be given credit for such an amazing explanation.
I was thinking the same, she explained this so clearly.
Yes this was excellently explained, kudos to her.
Or at least credit for being able to write backwards!
The connection between a human answering a question in real life vs how LLMs (with or without RAG) do it was so helpful!
Why. Chat gpt wrote it
IBM should start a learning platform. Their videos are so good.
i think they already do
Yes, they have it already. UA-cam.
Its mirrored video, she wrote naturally and video was mirrored later
They have skill build but not videos at least most of the content
They do, I recently attended a week long AI workshop based on an IBM curriculum
I love seeing a large company like IBM invest in educating the public with free content! You all rock!
Apparently there are scientists in charge who are pushing for such an agenda. Love to see it.
4:15 Marina combines the colors of the word prompt to emphasis her point. Nice touch

I love IBM teachers/trainers, I used to work at IBM and their in-house education quality was AMAZING!
Loved the simple example to describe how RAG can be used to augment the responses of LLM models.

As a salesperson that actually loves tech. This was an awesome explanation and the fact it was visual helped a ton!!!! Thanks
Your ability to write backwards on the glass is amazing! ;-)
They flip the video
@@jsonbourne8122 So obvious, but I did not think of it. My idea was way more complicated!
They're almost always left-handed as well...
@@aykoch she is right handed. when she writes, the arm moves away from the body. left hand arm would move toward the body. because the video is flipped, it's a bit of a mind trick to see it.
@@jsonbourne8122 Nice attention to detail as they made sure the outfit was symmetrical without any logos and had a ring on each hand's ring finger, making it harder to tell it was flipped.
this let's me understand why the embeddings used to generate the vectorstore is a different set from the embeddings of the LLM... Thanks, Marina!
Every time I watch one of these videos I'm amazed at the presenter's skill at writing backwards.

Thank you. So many people praising this even though it didn't explain anything that can't be googled in 2 seconds.
I watched and read so many videos/articles. This explained it so elegantly. Thank you.
We also need the models to cross check their own answers with the sources of information before printing out the answer to the user. There is no self control today. Models just say things. "I don't know" is actually a perfectly fine answer sometimes!
hold up - the fact that the board is flipped is the most underrated modern education marvel nobody's talking about
I know, right?!
Probably they filmed it in front of a glass board and flipped the video on edition later on
Filmed in front of a non-reflective mirror.
Just simply write on a glass board ,record it from the other side and laterally flip the image! Simple aa that.. and pls dont distract people from the contents being lectured by thinkin about the process behind the rec🤣
Is the board fliped or has she been flipped?
This is a fantastic video to learn about RAG in under 7 minutes. Thank you
For me, this is the most easy-to-understand video to explain RAG!
i was distracted by her ability to write lateraly inverted roman script while still thinking and explaining!!! Kudos

The explanation is good and easy to understand for a student like me who is new to this topic it gives me a clear idea of what RAG is.
One of the easiest to understand RAG explanations I've seen - thanks.
This video is highly underviewed for as informative as it is!
Great explanation. Even the pros in the field I have never seen explain like this.
Best explanation so far from all the content on internet.
I really like the analogy from the beginning! It was very smooth explanation! Well done!
Marina has done a great job explaining LLM and RAGs in simple terms.
Great down the rabbit hole video. Very deep and understandable. IBM academy worthy in my opinion.
lecturer did a fantastic job. simple and easy to understand.
I have no "Data Science" background. But I completely understood. You simplified this so unbelievably well. Thanks !
This is the best explanation I have seen so far for RAG! Amazing content!
That's what Knowledge graphs are for, to keep LLMs grounded with a reliable source and up-to-date.
This was such simple and clear explanation of complex subject. Thanks Marina :)
Wow, having a lightbulb moment finally after hearing this mentioned so often. Makes more sense now!
The video is short and consice yet the delivery is very elegant. She might be the best instructor that have teached me. Any idea how the video was created?
Please keep all these videos coming! They are so easy to understand and straightforward. Muchas gracias!

Straight to the point explanation that cleared my entire concept. Thanking IBM!
This explantation is one of the best out there.
Really comprehensive, well explained Marina Danilevsky !
Thank you for providing a thorough and accessible explanation of RAG!
Brilliant explanation and illustration. Thanks for your hard work putting this presentation together.

i had to think twice about how you can write in reverse but then i RAGed my system 2 :)
good explanation, it's very easy to understand. this video is the first one when I search RAG on UA-cam. great job ;)
I have watched many IBM videos and this is the undoubtedly the best ! I will be searching for your videos now Marina!
Amazing explanation. Starting from scratch and gained great perspective on this in a very short time.
Did all the speakers have to learn how to write in a mirrored way or is this effect reached by some digital trick?
There is a digital mirroring technique which is used to show the content this way...
She was right handed before the mirror effect
Writing on a clear glass, camera is behind the glass. It's like standing a glass and lookin at a person in an interrogation room
@Helixur you got my answer buddy!! Simple
The video just gets mirrored in in post production , Thats it
From which corpus/database are the documents retrieved from? Are they up-to date? and how does it know the best documents to select from a given set?
Thats one of the best explaination I have got so far ! Thanks a ton !
Very precise and exact information on RAG in a nutshell. Thank you for saving my time.
Thanks. Great video.
I've had too many conversations where Chatgpt has apparently just made stuff up. I know that's not what happens really, but it seems like it and it still makes untrue statements.
I'm glad researchers are working to improve things.
I spent all of the 1st watch talking while a friend watched it aswell trying to figure out is she is a robot because of the backwards writing. Good and fast info the 2nd watch. Great job
I was bamboozled by this type of video as well. It gets a lot simpler when you realize that all you need to do is mirror the video.
perfect explanation understood every bit , no lags kept it very interesting ,amazing job
Used RAG on Nolan's original interstellar script. Blew my mind with insights.
Loved this method of explaining concepts. Thank you!
Hey, JP here again,
Thank You IBM
the color coding on your whiteboard is really apt here !
Great, simple, quick explanation
The entire video I've been wondering how they made the transparent whiteboard
That's the best video about RAG that I've watched
