WEKA Tutorial #1.1 - How to Build a Data Mining Model from Scratch

Key Takeaways

welcome back to the data professor I'm Tennant I said a mad and in this episode I'm going to give you a quick introduction about what is data science and how you can go about building your very first prediction model so without further ado let's get started data is ubiquitous and in this day and age we have an ever-increasing amount of data infamously known as big data which we can use to analyze to get insights and to drive the decision-making process so what exactly is data data pertains to information about entities of interest for example health parameters of a human being such as the red and white blood cell count the blood profile lipid profile and other parameters that describes the health status of an individual characteristics of cars such as the top speed that it can go and fuel consumption rates properties of drugs such as the molecular size solubility electronic and hydrophobic properties of the drug simply put data science is a very big field that encompasses several smaller disciplines such as statistics mathematics data visualization programming data mining machine learning so as you can see data mining is a subset of data science and it refers to the specific process of making use of the data in order to build a prediction model and extracting knowledge from the data while machine learning refers to the learning algorithms that are used to create the prediction models inside the data mining process so there you have it a very brief introduction to data science now comes the fun part let's get started in building our very first prediction model Vica is a program for performing data mining it has an intuitive graphical user interface that allows you to pre-process transform the data as well as construct the prediction model using a variety of machine learning algorithms and it was created by two developers in Witten and EEP Frank from the University of Waikato so let's begin by first installing weeka onto your computer so what you need to do is go to a go to Google and then search for weeka and then click on the first link so notice that the URL is coming from the University of Waikato so click on the link so it's the pace that was open a couple of seconds ago so let's get started by downloading the program so click on the download button and then scroll down you'll notice that they they're going to have several versions here snapshot is when they have a like a beta version which is not stable yet but what you want is the stable version right here or they also have the developer version where they also provide new features which are not yet stable but are included for your usage here if you're into the latest feature you might want to try this one but if you're starting out I would recommend using the stable version so it has for many platform on the windows platform for the Mac platform and also for Linux platform as well so before you begin you will have to select one of the four links right here so what are they well the first link is the week program right here version 3 point 8 point three and it also comes with a java virtual environment as you can see from the final name for the 64-bit version however the second file is the weaker program alone as you can see here by the name of weeka and the version number three eight three and then x64 would mean it is built for the 64-bit version of Windows but it does not come with the Java Virtual Machine so therefore you don't see that JRE in the file name and the third file are is similar to the first file in which it has the weaker program along with the java virtual machine but it is built for the 32-bit version of your windows and the fourth file is the weaker program built for the 32-bit version so if you are wondering which version should you go with well let's check out what is the version of your computer's but it is 64 or 32 bit oh it's right here properties and then notice the 64-bit version right here so this computer has 64-bit so I'm going to go for it with the 64-bit version however I will have to identify whether I want to have Java or without Java so in order to do that let's check whether my computer has Java or not and you can do the same by going to the search icon type in CMD and click on the command prompt and then then and then you will see this command prompt window coming up type in Java and if it says that Java is not recognize that it means that your computer does not have Java installed so let's go with the first file which has Java prepackaged along with the weakest software so let's click on here and that will take you to the download link wait a bit ok and then your download have started so it's a hundred and fifteen megabytes so that should take you a little while ok so the internet speed is going up and we are a couple of seconds away from downloading the program ok so it's finished and let's install so click on the installation file and it will ask whether you want to allow this program to make changes to your device so I'll click on yes and then the next step is pretty easy and straightforward so click on the next button and we are close to completion and now it's going to install the java virtual machine you so click on the install button click on ok wait some more ok so we're almost there ok so Java has successfully been installed and I will click on the close button and then weeka say it's ok it is completed so once it's a complete head or click on the next button and then it has to take for us to take on start Riga and click on finished so until next time I'm telling
