yesterday we have seen the demonstration of classification root process on dataset employee dot air effect by using j48. okay here we have to use the employee.trf dataset okay by using that we have to classify by using the algorithm okay j48 algorithm is a uh extinction of idp [Music] construction okay we have seen id3 after that the extended version is c 4.5 the c 4.5 will be executed by using the algorithm called j4800 okay here also we are going to construct the decision tree tree like structural and output okay the same way uh the x-men six that is demonstration of classification group process on student dot erf by using j48 algorithm same classification same algorithm j48 algorithm but uh data set is different guys that is student.drff all of you write down the game for this experiment demonstration of classification demonstration of classification rule process demonstration of classification rule process demonstration of classification rules process and student dot error what is the data set we have to use here student dot arff data set what is the algorithm we have to use mainly determining okay classification that is one algorithm related [Music] next we are in the classification previously we have implemented j48 okay employee.drff know the student.trffff we have to use it here okay right uh to explain this one guys uh i'm going to prepare our dot erf that is what is the process we have today is first we have to create one text file here okay classification student okay while saying that we have to use save as search especially [Music] previously this is a text one guys okay whenever we have changed it to a ff1 [Music] [Music] right attributes okay what are the values it takes also we have to mention it okay at the rate uh for that one entering the attributes you have to use at the rate attributes attribute okay next what is the uh here i am going to take uh five attributes ph income student credit card rating buying is a computer or not okay these are the attributes this age income student credit card rating based on that one we have to predict that he is able to buy a computer or not okay for this one i am going to construct the student data set okay right uh what is the attribute here i am going to use this h okay what are the values it is we are going to use here is less than 30 next we have to use comma okay next 32 40 that is the second attribute next one is greater than 40 these are the three attributes next for each okay first we have to for entering the attributes we have to use income we have to use okay for that one we have to function what are the values i'm going to use in the data okay that is low income next one is medium okay and high income these are the three values it is taking attribute income these are the three values it is taking that next attribute is that is is okay now the next one is credit card rating nice at the rate attribute we have to use the rate attribute okay credit card rating these are the two values it is taking okay now last one that is uh at the rate attribute okay buying a computer that is the next one okay here it is yes or no okay these are the five attributes i am going to use for the student creation guys okay for a specific first the thing we have to mention is what is the relation name for that we have to mention that the relation nothing space followed by the name of the relation that is student here okay at reverse for mentioning the attributes we have to use at the rate attribute okay followed by different different attributes right okay here i am going to use five attributes for the student okay and moreover that while mentioning the attributes after the attribute name we have to mention what are the values it is taking also we have to mention it okay for that reason i have mentioned what is the values for the age what is the value is for the income what is the values for the student card rating buying a special computer okay computer or not okay no relation mentioning is our attribute mentioning and what are the values also now coming to the data for mentioning the coming data related to the data we have to use the rate data followed by data guys okay we have to separate it by comma less than 30 comma next second attribute that is income comma next one is uh student related information yes or no okay comma credit card rating sorry that is credit card rating i am going to use this fair next one is uh buying a special uh computer or not that is okay this is the rate first we have to mention the age that is less than 30 next income high and student s are no no credit rating that is fair and uh buying a special computer no this is the one data guys likewise i'm going to mention the different person's second one 30 less than this is the age and the next one is income high and the next one is student or no no okay next one is credit card rating excellent next one is buying a special computer now okay this is the second person data likewise i'm going to enter the third person data body comma income high comma student sr no no the particular this data okay right three process data entering is over let us go for the fourth person that is greater than what is the age okay come on next one is income medium next comma okay is no not a student next his credit card rating is fair this is the computer by next one is greater than 40 again low yes fair [Music] yes next again greater than 40 low yes that's it this is the data for okay likewise next letter that is 30 to 40 h next income no next student is excellent is uh okay next less than 30 sh form a medium computer okay exponents less than 30 next low is the income next student is next fair no the next one is greater than 40 is the age next median next yes yes less than 30 media yes excellent yes 3240 select yes 30 to 40. right [Music] greater than 40. that's it 11 12 13 14. okay let us serve this one okay i've saved this one yes okay information is there okay okay now we have to open the become we have to give it this one as a input for uh so you can just [Music] once it is open okay we have to load this uh student. after that we have to select the classification button and we have to select j48 it's going to show some information after that you have to view the tree structure okay because step by step what we have done also we have to write it in the observation guys step by step what we have done that is also you have to include in the preparation shhh and just continue uploading uh so never caught [Music] now we have to select the explorer noise okay window okay we have to open your file you have to do that so so okay so this is the information guys okay these are the five attributes h okay we have to pre-process this one okay is there any mistakes three okay then equal is zero these are the values for that one next for the student our missing value is two inequalities zero next one is zero distance r is zero [Music] uh then you should try the j4800 you have to select it okay these default values you guys don't have to change anything okay okay more will give us the information related to this classification g48 algorithm okay okay having capital keys if you want to see this is the thing you have to press it okay after selecting the term we have to press start okay to use the information like this how many what classified instance is 78 percent okay incorrectly classified instance 21 percentage so that is the acceptable thing we have to press okay view then visualize the tree okay here also you will have the different different values so dp rate if the rate uh precision and confusion matrix also it is generated okay to view the decision tree we have to preserve the result list and we have to select which one we are going to visualize that okay this is the trigger which whenever it is less than 30 okay he's unable to buy a computer 30 to 40 is a victory computer okay when it is when he says is greater than or equal to 40 means okay based on the credit card rating he is able to buy a computer credit [Music] observation that is 35 days of accuracy okay for income the accuracy rate is correctly classified instance is 14 take the student okay his law is a student okay median not a student income iii is not a student okay this is the district [Music] [Music] foreign foreign [Music] okay we have to select the open file and we have to give them okay not a rff file this is the air ffa after that one it is showing the attributes okay and their values for age uh the missing values are zero okay income missing values are zero and the student attribute missing values are zero and credit card rating the missing values are zero okay buying a special computer uh that is also missing value is zero guys okay now we have to go for the x-men that is excellent name is demonstration of classification rule process on student.arff by using j48 algorithm okay means we have to select the class a and we have to choose the j48 that will be there in the trees okay after selection that one for more information if you have to press the show the information related to the j48 and capabilities of j48 okay we have to press the camera matrix to show some information okay only to change any default one is after that one just press start button okay once the start button is pressed it will show the information related to that one classification information correctly classified instances 11 that is 78 percent incorrectly classified instances 21 percent okay okay that will show the different confusion matrix information different error rates okay and different different accuracy values also it will give the information okay so to get the tree structure we have to press on the okay result list okay select just one we have to visualize that just it will use the information related to the uh given data okay whenever a is equal to less than 30 okay he is not able to buy a computer that is the specification and whenever the is equal to 30 to 40 is able to buy a computer whenever 30 greater than 40 means you have to check the credit card rating if it is okay when the age is greater than 40 means credit card rating we have to check if it is fair means he is able to buy a computer okay whenever the credit card rating is excellent he's unable to buy computer case this is the overall information okay in the form of tristan understand guys likewise guys now we have to change it okay i have specified the leaf nodes as a buying a computer likewise we can change it okay for suppose i have for my age i am going to construct correctly classified instances here 35 incorrectly classified instances that is 64 okay likewise nature particularly buying a computer doctor we have to select that one okay start okay for this one accuracy rate is 17 okay correctly classified instances is 78 percent incorrectly classified instance percent okay the injection to that one uh in the summary it will increase the other information like mean absolute error statistic okay root means where error all these errors okay likewise it will also display confusion matrix also correct [Music] different to view the new structure we have to press this okay on the result list it shows the time also that's the energy this is the one we have to write it in observation okay finally for the classification j48 gives the tree like structure by using that one we are going to predict the unknown class like this right for suppose no person came okay says is in between 3240 he is able to buy a computer how we can recheck his is between the 30 to 40 what is the value here yes means he is able to buy a computer likewise for suppose one person came in 45 years age okay again we have to check that person's credit card rating okay uh his credit card rating is excellent then we can say that he's not able to be a computer okay right in this way we are going to classify the unknown class labels okay we are going to predict how he is able to buy a computer based on this pre-structure right okay by using that one we are going to use you have to write down the all the overall process okay step by step process okay finally you have to write the year of f5 okay finally how we are going to generate the tree also we have to write it in the process case okay step by step you have to write it you know six exponents is completed lay down this weekend this red now
