 So, what I was actually telling you about the machine learning is that I mean other than machine learning you have to learn the technologies. So, we will have we will learn a lot of technologies which are associated with the analytics ok. Now, we have about two projects one is the create analytics report for Sunbird LMS. So, for that purpose we will be using the Sunbird data APIs and the Sunbird telemetry service ok. And the second is the enhancement of the open edX analytics. I think the my previous one Ropona has already talked to you about the open edX platform, but it has got an analytics platform which is separate than the open edX platform. The one which she talked about is a LMS and CMS that is a learning management system and content management system. So, that is a separate site and analytics is a separate site. So, you have to go from the instructor dashboard to the analytics site ok. So, we are talking about the enhancement of that analytics site ok. So, this is the whole purpose is to measure the effectiveness of FDPs of a faculty development program which is conducted by IIT Bombay X. So, in the faculty development program they have introduced some few measures to find out how effective is a course is. So, our whole idea is to give them the metrics of that that is whatever they have introduced the new features we have to give the metrics of those features. Now, first we will talk about the create analytics reports for Sunbird LMS that is learning management system. Now, that LMS Sunbird has got these components organization, users, courses, assessment forums and services like data API, gateway, telemetry services etcetera ok. So, organization is if they cater to different organizations. So, we you can have the organization data. So, whenever you are doing the analytics we will be doing the analytics for a particular organization. So, you need to use that organization data. This is for the users that is if you want to have a particular user or the collective collection of users we have to use the users database. Then you have the courses which is the content of the course then assessment is actually the quizzes. So, which you will be using to assess how much the learner has learned. And then forums, forums they have got some discussion forums in which the participation and other things that is how people are participating that we can find out. And all these things you can get from the using data API gateway that is you have to use data API you can you cannot directly access the data you have to use that API and their authentication service to get the data from the data API. They already have some analytics which is in two categories one is a creation analytics another is a consumption analytics. And for that you have to specify the duration during which you want to have the analytics figures. So, creation analytics is the like total number of contents created, total number of authors, total number of reviewers. This is actually the number of things that number of total content created on the portal. So, that kind of things and then you can download the reports using the CSV format. And the consumption analysis is that how many people number of users has visited the site then content consumption that is how much time they have spent on each content. So, average time spent by user power is easy. So, all these things are already available you can get it from their sorry dashboard. Now, we are I will be coming to that talking about the installation types this is important because we have to know which installation will be using for our development purpose. So, one is that first is that you can install it on your machine this is actually basically a portal installation and another is a medium scale installation. Now, in the first installation it will install only the front end and in the second installation it will install both the front end and the back end ok. So, but right now this medium scale deployment is not available which my earlier speaker dockers this he said. So, they will be installing using the dockers. So, that it uses a docker technology that medium scale deployment ok. Now, we will be using only developers installation. So, which is a portal installation and front end is a portal back end is a cloud instance of the sunbird which they have installed for the purpose of demonstration and usage of APIs. And you have to configure the sunbird portal using that API you have to get a API key from their authentication token and then you have to I mean use that for installation in the cloud. And the technological I mean technical components which are used is mostly node jays, angular jays and jquery angular jays used for the portal front end node jays is a back end and jquery is used by both of them. So, you will be using this one for creating reports and for creating reports you will be using the APIs. They have got four categories of APIs, feature APIs, administration APIs, setup APIs and data APIs. Second thing which you will be using is a telemetry service. Telemetry service is actually the logging of the events. So, that is most necessary for the analytic purpose. So, when they are doing this telemetry that even capturing they have got some standard structure where they have who is doing it which what content is accessing then where in which context all those things come in the whatever results they send the telemetry data which you get by sending the request. And in the telemetry request you have to have the auth token which you have to take from them. They will generate the auth token and will give it to you then you will be have to use a channel ID that is which content API key and they have got the standalone JS library for telemetry. So, you have to use that library.
