1 00:00:05,380 --> 00:00:12,520 In this lesson, we will give a brief introduction to the level two application. 2 00:00:17,850 --> 00:00:27,300 Remember that the level two application A is very similar to the level one application, which is the 3 00:00:27,300 --> 00:00:33,810 toy demo, but the level two application includes what we call a toy user interface. 4 00:00:33,810 --> 00:00:37,980 In this case, we are going to use a Streamlit as a toy user interface. 5 00:00:37,980 --> 00:00:41,880 Why do we call Streamlit a toy user interface? 6 00:00:41,880 --> 00:00:49,290 Because as you will see, extremely it is a very temporary, provisional kind of user interface. 7 00:00:49,290 --> 00:00:54,660 It's nothing like the user interface you are going to find in the professional applications. 8 00:00:54,660 --> 00:00:56,340 We will see why. 9 00:00:56,340 --> 00:01:01,410 It may be interesting for you to use Streamlit in some situations. 10 00:01:02,520 --> 00:01:03,390 So. 11 00:01:04,370 --> 00:01:12,470 A remember that the level two applications are still not the kind of applications you are going to find 12 00:01:12,470 --> 00:01:14,690 in the professional environment. 13 00:01:14,750 --> 00:01:20,930 These are applications that you will find in the proof of concept phase. 14 00:01:20,930 --> 00:01:23,390 We will talk about that later. 15 00:01:24,660 --> 00:01:32,190 The important thing is that the functionality, the long chain functionality you are going to see in 16 00:01:32,190 --> 00:01:35,790 the level two applications, you already know it. 17 00:01:35,790 --> 00:01:39,750 So this is not going to be anything new for you. 18 00:01:39,750 --> 00:01:47,580 The only thing we change is that we are going to include the toy user interface with Streamlit, and 19 00:01:47,580 --> 00:01:54,600 in order to work with Streamlit, we need to rearrange some parts of the long chain functionality. 20 00:01:54,600 --> 00:01:55,770 You will see that. 21 00:01:55,770 --> 00:02:03,270 So we will go one by one by one, uh, with the level two applications. 22 00:02:03,270 --> 00:02:05,970 And you will see a demo of the application. 23 00:02:05,970 --> 00:02:09,389 And you will also see the code of the application. 24 00:02:09,389 --> 00:02:14,100 We will also see a brief a. 25 00:02:15,620 --> 00:02:23,390 Extremely introduction, we may say so the kinds of a well, some notes, some previous notes. 26 00:02:23,690 --> 00:02:30,980 Remember that extremely it is a suitable solution for the proof of concept concept phase. 27 00:02:30,980 --> 00:02:33,080 We'll talk more about that later. 28 00:02:34,220 --> 00:02:34,670 Extremely. 29 00:02:34,670 --> 00:02:40,730 It allows us to present and test what some people call end to end. 30 00:02:40,730 --> 00:02:51,080 Application in my opinion, is a little bit tricky to call level two applications and end to end application 31 00:02:51,080 --> 00:02:56,900 because they are just toy demos at the end. 32 00:02:56,900 --> 00:03:04,430 So when when someone tells me about an end to end to end application, my understanding is that they 33 00:03:04,430 --> 00:03:10,880 are referring to a professional application, a full stack application, as we will see with a level 34 00:03:10,880 --> 00:03:11,870 three application. 35 00:03:11,870 --> 00:03:14,990 In this case, the level two application. 36 00:03:15,080 --> 00:03:24,680 Even when some people in other courses A and blog posts and YouTube videos call them end to end applications. 37 00:03:25,160 --> 00:03:33,140 In our opinion, they are not end to end applications yet they are still in the demo, uh, side of 38 00:03:33,140 --> 00:03:33,710 things. 39 00:03:33,710 --> 00:03:42,920 So extremely it allows us to present and test demo applications is a simple and a fast way to have user 40 00:03:42,920 --> 00:03:51,440 interfaces for your LM app demos, and it can be loaded into the cloud at no cost. 41 00:03:52,370 --> 00:04:01,490 This is something you will see a to create a level two application is a good way to have a demo. 42 00:04:01,490 --> 00:04:10,520 You can share with your manager, with your uh, with your customer, with your user, but always with 43 00:04:10,520 --> 00:04:14,090 the a warning that this is just a demo. 44 00:04:14,090 --> 00:04:22,250 This is not a professional project, but they can see like a user interface, um, you know, is not 45 00:04:22,250 --> 00:04:22,700 the code. 46 00:04:22,700 --> 00:04:26,630 They have a user interface there, so it's more user friendly for them. 47 00:04:27,320 --> 00:04:27,980 A. 48 00:04:28,990 --> 00:04:35,230 So extremely to allow you to create simple but functional demos. 49 00:04:35,560 --> 00:04:43,000 And remember that, as always in this field, some of the exercises and apps level two apps we provide, 50 00:04:43,000 --> 00:04:51,520 they may not work in the near future if the packages they are based on are updated or changed, uh, 51 00:04:51,520 --> 00:04:56,530 in the next month or or or or whatever. 52 00:04:56,530 --> 00:04:56,980 Right. 53 00:04:56,980 --> 00:05:03,100 So remember that the important thing at this point is the conceptual learning you are going to make. 54 00:05:03,100 --> 00:05:05,890 So we are going to try to keep them updated. 55 00:05:05,890 --> 00:05:16,630 But in case you see that any of these apps, uh, do not work because any code update, uh, don't worry 56 00:05:16,630 --> 00:05:17,140 about that. 57 00:05:17,140 --> 00:05:25,150 Just keep the conceptual learning in mind and try to fix if there is something to fix. 58 00:05:25,180 --> 00:05:33,880 Uh, at the time we are going to see a five categories of level two applications. 59 00:05:33,880 --> 00:05:43,210 We will see some applications that are able to write content, some in order to improve your content, 60 00:05:43,210 --> 00:05:48,550 some in order to create new content, new content from a topic. 61 00:05:49,120 --> 00:05:55,990 We are also going to see apps from, uh, what we can call the summarizing category. 62 00:05:55,990 --> 00:05:58,480 So we are going to summarize a file. 63 00:05:58,480 --> 00:06:01,990 We are going to summarize a text. 64 00:06:02,050 --> 00:06:08,470 We also will be working with what we can call extracting apps. 65 00:06:08,890 --> 00:06:13,270 Uh, in in in the particular example you will see. 66 00:06:14,000 --> 00:06:22,850 We are going to extract key data from product reviews and then two more categories, a rag. 67 00:06:22,850 --> 00:06:28,400 So we are going to see a couple of level two apps and using the Rag technique. 68 00:06:28,400 --> 00:06:35,030 And finally we will see one app that we can call evaluating app. 69 00:06:35,030 --> 00:06:42,230 So it's an app that is going to help you evaluate uh, other apps okay. 70 00:06:43,110 --> 00:06:51,630 So in this lesson, we have provided a brief introduction to the level two applications uh section. 71 00:06:54,860 --> 00:07:00,980 In the next lesson, we are going to talk about the proof of concept phase. 72 00:07:00,980 --> 00:07:02,000 What is it? 73 00:07:02,030 --> 00:07:09,710 What is the difference between the proof of concept phase and the production phase and some, uh, interesting 74 00:07:09,710 --> 00:07:11,270 comments about that.
