do you agree that this legendary channel is better than most paid courses for coding out there?

[@toddmarshall7573]

Having programmed since 1963, it looks like a return to COBOL. Programming today is 90% getting things hooked up. 10% getting things done. 100% being clueless as to what's going on under the covers. Follow the bouncing ball programming.

Wow the instructor for this vid was actually amazing. I only clicked on it because It was 30 minutes long, having no real intention to actually learn and just have play in the background while I read a textbook for fizz. The instructor was phenomenal, I understood everything she said, every instruction was clear to follow although I only really know some JavaScript and cpp. I actually learned a few things. Before the video began like I said no real intentions of implementing this but since I actually learned and understood pretty much all of it I could see myself actually implementing it on some project and adding it to my resume. Would be cool. Thanks

I did this in my Numerical Analysis course using Maple and MatLab. Then i did some analysis on images when i took Fourier analysis. Shame i never got much chance to use it professionally, as i tend to work with financial data.

[@meguellatiyounes8659]

[@jasintanuwijaya5203]

When we do ask question using the vector database like "what are the biggest questions in science" does it consume token from open api also?

8:50 this is where I’m stuck in my project. Looking for a way to “inject” rule based text embedding, like an indicator variable, the shows the text belongs to some parent structure. Similarly, want to create custom embedding function that will be highly weighted for certain regex text patterns. Need to guarantee that cos similarly is 100 percent if regex matches. Are text embedding the right approach?

[@rafaelbatres5280]

Amazing explanation! How could I use an existing Access database for my data set? It actually contains text reports and keywords for each report.

[@assesino8346]

[@myslates2854]

This is a very good video but I would like to understand why do we need datastax and store in DB if the intension is just to use as prompt and get answer. We can get directly from the OPenAI with key and prompt without storing or anything to do with vector embedding and those will be internal to OpenAI, I wanted to understand the use case of approach.

[@chidiebere]

Valid question

[@giovanimaciel1651]

I believe this method is better than fine-tuning and significantly superior to using prompts, especially when you have a lot of information; the chat will provide much better answers.

[@user-ss1or5jh5b]

When calculating cosine similarity, does a value closer to 1 mean more similar and a value closer to -1 mean less similar?

[@opalrun]

1 indicates an identical vector, or very close semantic meaning, or even identical text. (Note that it's the similarity of the vector's direction only, not scale.) 0 indicates an orthogonal relationship, ie, unrelated semantically. -1 in theory represents complete semantic opposition, but in practice, a perfect -1 is rare in natural language contexts.

This tutorial is very interesting, except that without a paid account on OpenAI we cannot really put it into practice. But I can't afford to pay 20 euros per month just to set up a tutorial.

[@donaldoalmazan7338]

You don't need to sign up for OpenAI Plus in order to create an API Key, they are billed separately. You also get a free 3-month API credit when you first create an account, the amount varies, I think they've decreased it now to about $5 (unfortunately I missed out on my credit, since I created my account last year and wasn't coding anything)

[@PopCultureQuest]

@@donaldoalmazan7338 thx for info

[@kevthedestroyer1044]

actually the 20$ for chatgpt is different from the api, for the api you can for example buy a 10$ credit and use it for as much as you would like, as long as it's used to finetune it will last long

I did not understand how the LLM (OpenAI) uses the embeddings stored in the DB.

[@FamilyManMoving]

LangChain: "chaining" resulted in two answers for each prompt: "I don't know" and the headlines. The first answer came from OpenAI's LLM, the second answers (the headlines) came from the vector-DB (Astra/Cassandra) that she set up outside OpenAI. LangChain was the bridge between the two. It's a simple little example without much relevance, but it shows the bones. There is a lot more work to make something useful. For instance, you could use a pre-trained LLM to perform the organizational tasks and composition (the language parts) using current data from a real-time source. For instance, "what kind of activities would be good at Los Angeles beaches today?" The LLM could contextualize the meaning of the question using pre-trained data (an understanding of what constitutes beach sports and the condition necessary for each is something that won't much change over time), and then use an external source (weather channels, surf sites, diving data sites, sailing sites, etc.) to search for real-time conditions at LA Baches. The LLM - using the current real-time data - could then look for nearness matches based on how the conditions match up to certain sports. So instead of a generic pre-trained answer like, "people like to sunbathe, swim, dive and surf at beaches" you can get a specific answer such as, "The conditions at Redondo Beach suggest it's a good surf day, but rip tide warnings suggest it is a bad day for people to be swimming. There is a water quality alert for bacteria in Santa Monica Bay." The LLM used the external real-time data to give accurate point-in-time suggestions that it would otherwise never have using data from training months earlier. That's where LangChain can help - merging "new" or custom data into the pre-trained contextual LLM model. Hope this helped.

4:40 "...Joe is 38 on the 0 to 100 scale... so -.4 on the -1 to 1 scale...": How is that? I get -.24. If it's -.4 on the -1 to 1 scale, that's 30 on the 0 to 100 scale. Please fix my math.

[@FamilyManMoving]

Context has two flavors, near and "not near". Joe is 38% near. Maybe Alice is 40% "not near", which would equate to a negative value (-.4). So context is more than "this one is like the other", it's also "but it's not like this other thing". If we just used a single dimension, then literally everything would be "like" everything else, which makes it a little difficult to differentiate. "The school bus is yellow. A banana is yellow. A bus is NOT LIKE a banana." Dimensions in dimensions.

It is disappointing that you have taken the route of OpenAI which is far from open - not only have they not open-sourced their models, their payment methods are limited to a few options and setting up billing is required for their API to work. It would have been much better to use free, open-source models to demonstrate LangChain.
