The mere fact that every large player in this space has videos teaching people about these things means this is super super serious.
Or that it is a massive massive waste of time and effort
@@ChatGTA345 unlikely. 1 or 2 small companies pursuing this tech with such ambition could be a waste of time. But if all the big players are investing their time and money in this tech, then it has to be something very real and very serious
@@zappy9880 I don't think that necessarily follows. The industry has followed so many hype waves before. The competitive advantage is actually not to do what everyone else does
@@ChatGTA345 😊😊😊😊😊😊❤
@@ChatGTA345 well, it is a waste depends on how you use it. but can really be useful in several fields if you know how to use it and how you fine-tune it. just treat it as some sort of assisting tool as of now, and not as something that you actually use as some sort of definitive source of knowledge.
Fantastic presentation...and...(I LOVE THIS) NO ANNOYING BACKING TRACK!! Thank you, Google!
Thank you for making this available to the general public!
Finding answers to questions has become so much easier now with new tech. I have never been good at writing code, so this is a welcome change as far as I'm concerned! Look forward to more progress in technology.
Be careful in the world to come being reliant on these AIs without developing any specific field will make you obsolete in future society
Thank you. I understood about half (optimistically) of it. I subscribed to the channel hoping to start from the beginning and understanding more. My ultimate goal: a LLM Librarian, combining the catalog of a library with results from internet search engine, giving the deepest answer possible.
Appreciate the valuable content! Sharing some key takeaways of the video and I hope this can help someone out.
1) 00:50 - Large language models (LLMs) are general purpose language models that can be pre-trained and fine-tuned for specific purposes.
LLMs are trained for general purposes to solve common language problems, and then tailored to solve specific problems in different fields.
2) 02:04 - Large language models have enormous size and parameter count.
The size of the training data set can be at the petabyte scale, and the parameter count refers to the memories and knowledge learned by the machine during training.
3) 03:01 - Pre-training and fine-tuning are key steps in developing large language models.
Pre-training involves training a large language model for general purposes with a large data set, while fine-tuning involves training the model for specific aims with a much smaller data set.
4) 03:15 - Large language models offer several benefits.
They can be used for different tasks, require minimal field training data, and their performance improves with more data and parameters.
5) 08:50 - Prompt design and prompt engineering are important in large language models.
Prompt design involves creating a clear, concise, and informative prompt for the desired task, while prompt engineering focuses on improving performance.
6) 13:43 - Generative AI Studio and Generative AI App Builder are tools for exploring and customizing generative AI models.
Generative AI Studio provides pre-trained models, tools for fine-tuning and deploying models, and a community forum for collaboration.
7) 14:52 - Palm API and Vertex AI provide tools for testing, tuning, and deploying large language models.
Palm API allows testing and experimenting with large language models and gen AI tools, while Vertex AI offers task-specific Foundation models and parameter efficient tuning methods.
This takeaway note is made with the Notable app (getnotable.ai).
Can't wait to see demos at GoogleIO
Actually, really helpful, thank you Google.
Wondering how far this technology will go in the next couple of years, if it's this far already in a couple of months.
we all wondering too ;)
This is one of the educative sessions I've come across
very well and understandable explained... good job!
Great video! Thank you!!
Very comprehensive video! Thank you guys!
This was fantastic! While I've been watching The Full Stack LLM Bootcamp, I'm not technically strong enough to start there, and will use these Google Cloud Tech videos as a means to "jumpstart" my knowledge of LLM and Generative AI. This is a great general primer for students and colleagues!
Thanks for referencing Full Stack LLM Bootcamp, A great resource I was not aware of.
proximity and stream for seek time reduction..memory in case reduced latency, can also be optimized for seek time and pattern analysis.
Minor Correction @ 2:14. "In ML, parameters are often called hyperparameters." In ML, parameters and hyperparameters can exist simultaneously and serve two different purposes. One can think of hyperparameters as the set of knobs that the designer has direct influence to change as they see fit (whether algorithmically or manually). As for the parameters of a model, one can think of it as the set of knobs that are learned directly from the data. For hyperparameters, you specify them prior to the training step; while the training step proceeds, the parameters of the model are being learned.
Nice
Thank you John. I believe you conflated model parameters and hyperparameters at 2:16. As far as I know, these are two different concepts.
Yes, they are different conceptually. Parameters are directly applied/calculated in the hypothesis or model; while, hyperparameters are somewhat heuristically decided based on what works. For example if you were figuring out how to get from home to office, the path details maybe calculated directly by the GPS, but the time at which you leave maybe heuristically decided by you. Another example of a hyperparameter can be how many backup cameras you choose to add should the main camera fail on a robot, there is no 'correct' number, it's more of a cost or design choice. In an ML transformer, choosing the number of encoders or decoders can be a hyperparameter. The parameters would be learned from the language training in the LLM.
Agreed, two totally different things. It's not great that the video encourages this confusion.
Thank you for teaching.
Always great to learn from GCT!
Excellent Presentation Sir ... truly i admire it 😍😍😍😍
Wow!
Thank you for this very useful video so well explained!
great content! make me feel like an expert now💯
Great explainer. I'm a little less anxious about AI taking our jobs.
1980s or so, there were telephone operator who connects those STD lines.
Now they are vanished but their next gen kids are employed in another market.
That's how innovation works!!
Time to start my own
Very Informative - Thanks for sharing 😊 prompt design and prompt engineering would take make the conversation more realistic and accurate.
Thank for sharing👍
helpful for me,tks google
Exciting stuff.
Waow! Such an eye-opening knowledge!🤓
Nice one!
If you define the problem you are trying to solve first
Then reason from their
Wouldn’t it be more efficient?
Nice.
2:47 You mentioned the parameters are hyper parameters is incorrect and confusing
is it true that AI models like ChatGPT or Bard are fed in with codes (like programming languages) as well?
0:57 What do pre-trainned and fine-tuned llms means? Good analogy with dogs.
can u share awesome slides ?
Very slim on the prompt engineering education. This is a very important skill!
Cool!
At 4:50 I did not understand the third point that the speaker made i.e. "Orchestrated distributes computation for accelerators". Can someone please explain?
you can use a new drive architecture sought via gpu pixels for proximity stream like to not need large.lamguage models, and use multi factor checks to reduce need of a lot of data..thank me now.
proximity and stream for seek time reduction..memory in case reduced latency, can also be optimized for seek time and pattern analysis.
I'm with you
i love it
This is a great overview video thank you.
Do you have a reference for how to host open-sourced LLM's in Vertex AI (or other GCP tools)? Overall I'm looking for GCP tools and ways for turning open-source LLM's into API's to be used within our native cloud instance.
You lost any semblance of an answer from @Google Cloud Tech the second you said "open-source"
@@B2M2948 lol.
I still want to host the Open source thing on their platform so I thought there might be a shot.
@@coryrandolph8501did you ever figure it out?
@@andrestorres7343 Yes, but it was really pricey since you have to host the underlying infrastructure. Usually large GPU virtual machines and on GCP depending on model size it was $2k - $5k per month to host an open source model.
We are sticking with the API version of the big models because of this.
What does 540 billion parameters mean , and how do you pass those to your model ? What kind of computational processing power is needed for this ?
You don't have to pass the parameters. In Llm you just send the data as text and it must be able to tokenize the text.
You first instantiate the model with randomly generated parameters (540B in this case) and use lots and lots and lots of data to make the model "learn" and modify these parameters so they are better. For llms, you need hundreds of powerful gpus and you need weeks or months to train such massive models. Falcon 40B which is a state of the art open source model with 40B parameters was trained for two months.
@@MrAmgadHasan chatgpt was trained for about 2 years , there are 2 seperate models within chatgpt , one to understand context, the other to predict the text 🤪
@@artus198 chatgpt is not a pure LLM. It was finetuned using multiple instructions datsets and RLHF. I was talking about training pure LLMs
please provide link to the slides
where can i access gen ai studio and build apps?
For the fellow beginners:
PETM is also called PEFT
pattern analysis with causal.
What is the legal status now of LLM models trained on proprietary data ?
lol
Japan legalized them.
I have an urgent question (school related) -> is LLM part of NLP? Is an LLM always an NLP model? Or can an LLM be another kind of model? "L" for Language in both kinds of models. Both in AI. Both for language.
A colleague says LLM is not necessarily an NLP model but then I did not understand LLM and/or NLP and my oral exam is in few days omg
Also, BERT is Transformer but not an LLM, right? Transformer can be LLM or not, right?
Reversible computing is still the future regardless of whether people would like to admit it or not.
What do you mean
@@IForgetWhatISay I mean that in the future, all computers will be reversible computers. Reversible computation will take over AI.
@@josephvanname3377 ah I just looked it up. Interesting. Thanks
Do LLM charge money for using them
Can I have these slides please?
What's a TPU V4 Pod? Sounds like a Turboencabulator, or?
It's a custom built computer chip developed by google to perform matrix operations and train deep learning models. Think of them as gpus specialized for deep learning.
A pod is "rack" of tens or hundred tpu/gpu.
I've been extremely frustrated in my interactions with chatbots, they never seem to tell the truth and it's getting harder and harder to tell what's true from what's not. I honestly like regular Google searches much more!
11:45 Can anybody explain the difference between these two prompts?
I understand the message of this slide to be not about prompt design, but AI response: that if the app in which the model is embedded first instructs the model to describe the process to get to an answer and THEN feed that back in with the original prompt, that the quality of the final response improves.
Can users teach AI?
RIP Bard, gone so young..
whats the name of the last circle at ua-cam.com/video/zizonToFXDs/v-deo.html ?
😊😊😊😊😊😊😊☺️☺️☺️☺️👌👌👌👌
Google 👍
Creating a prompt seems more of a "Craft" than engineering.
Citizen Kane9 :D
Anybody who read this comment, you'd want to type this prompt in Chat-GPT or Bard: "I have 15 liter jug, 10 liter jug, and 5 liter jug. How do I measure 5 liters of water?" ---> See what they answer
Is it just me or the quality of google training videos has gone down?
Yes. They made a mistake when they described parameters as hyper parameters and the chain of thought part wasn't clear.
So a prompt engineer is anyone with common sense?
We are creating our own prison...
passed
Why so few comments
This felt more like advertisement for Bard. Not very helpful.
It is both advertising for bard and helpful too.
Was this long? YES.
Did I learn? YES.
Did I want to sleep? YES.
Did I sleep before the end? NO.
A WIN
Really helpful video, but dont understand why it's called intelligent because it cannot discover something on its own
It can. Once you feed the base of information, it can learn from the questions themselves leveraging possible answers for accuracy. Hallucinations will happen but that's when you start fine tuning it with the correct answers that it could not find on its own or on its data base. A human can't learn everything on their own, we need to study content which is build over time through observation.
