@ 12:14 teams.corr()["medals"] didn't work for me so I did corr = teams.drop(["team", "country"], axis=1).corr()["medals"] print(corr) for those who are also running into the same issues as me :)
Thank you for providing such a great resource and making ML so digestible! YOU are who introduced me to machine learning, and I love it. I'm looking forward to applying everything I learn to my own projects!!!
Thank you for the amazing video! However, when I tried running this, I received a value error teams.corr()["medals"] This seems to be because the "Team" and "Country" column are in string, and hence making it impossible to get a corr value. So i removed them just to obtain the corr values. But it seems to work for you without filtering the string type columns out. Any ideas why?
Albania was in the olympics 1992 and i guess any other countries in that csv were also. They just did not win any medals, that's why there are missing values. So actually setting them to zero instead of dropping them is more accurate. In theory you would prefer first or second party data, in this case u would have to do some research to clarify the reson for missing values in the data set.
In step 5 the formula is not the mean absolute error.. you are missing the 1/D. Training with data that us wrong and fitting linearly when it seems exponential.
sir that was really simple and very well explained also excellently organised...... yet I struggled at one point I couldn't convert string(teams) to float while performing the corelation....if you see this hope you reply .....
There seems to be a problem when I run 'teams.corr()["medals"]'. Keeps throwing an error "ValueError: could not convert string to float: 'AFG''. Checked unique values and NaN. confused!
I faced the same problem as well, but managed to solve it. The error is due to some columns in teams that are nonnumerical like team and country, so i created a new table, ie teams = teams.drop(columns = [‘team’, ‘country’]) and it should work. Hope this helps.
Would love a math course that is shown directly relating to ML that I can take to get up to speed. for someone that might be self taught in tech w/ only a highschool education
It will be a good pratcise to use x_test,y_test,x_train,y_train instead of predictors, target, and it wil also be a good practise to use x , y as independent and dependent variable instead of test , and so on
Thank you for such a nice video! I have a question though about the error_ratio. You said countries like FRA, CAN, and RUS get a lot of medals in the olympics and it shown that their error ratio is low. With what should I compare the value of error_ratio?
Hi , I really loved your video. I was trying to follow along, but got an error and cant move forward. I would love it if you could help me fix it. i got an error for the predictions = reg.predict(test[predictors]). It kept saying ValueError: The feature names should match those that were passed during fit. Feature names unseen at fit time: - age - country - medals - team - year what do i do?
I bet this is an issue with doing it locally and not using a Jupyter Notebook because I had this problem as well. The best way around this is: teams.corr(numeric_only=True)["medals"] That will only generate value against numeric fields.
Maybe you meant IDE (integrated development environment)? Python only has one interpreter, it's builit-in and it compiles/interpretes the code. I'm pretty sure the IDE he is using in the video is Project Jupyter (interactive development environment) which is pretty much a standard environment in machine learning, data analytics, statistical analysis etc.
Sorry, of course I meant IDE@@eduardtoronto What differs from mine (PyCharm) is that the code gets executed immediately and the result are showd. I have to use the print command for that. Or is the video just edited?
@@baeche In jupyter ENTER inserts a new line, SHIFT+ENTER executes the code. Everything gets executed immediately. It depends on the functions he's using e.g. copy() gets executed but it wont print any output whereas something like 'shape' will output the result to the console like print.
Thank you very much@@eduardtoronto I moved to google colab where the last command gets printed too. I find google colab handy as I can work in the browser. Where I experience problems is accessing a SQL Server (not SQ Lite, mysql). Any idea where I can look for help? ChatGPT could not.

I was just studying the concepts for so long and getting overwhelmed, this video definitely helped to get the bigger picture.
Exactly bro can you tell me what you did after this to become better in machine learning
First person i saw who is explaing just perfectly and can be understand by a student thanks ane keep it up sir.
@ 12:14
teams.corr()["medals"]
didn't work for me so I did
corr = teams.drop(["team", "country"], axis=1).corr()["medals"]
print(corr)
for those who are also running into the same issues as me :)
It worked thanks
or u can use teams.corr(numeric_only="true")["medals"]
@@rohithsrisaimukkamala thank you!

love the simplicity of your step by step method. I am absorbing a lot in just one pass. Thank you and well done.

Perfect. Best video I’ve found precious and easy to understand so far. Thank you
Thanks a lot , it helps to understand ML with basic steps
This video realy shows how things are done.

A great video!
This answered some of my questions. Thanks
Glad it was helpful!
thank you so much!!! you are a really good teacher
I like how you showed to use the later data to test the model, but do you have a video that shows how to use the data to predict the future Olympics?
insightfull sir, thanks in advance
Thanks! This video is exactly what I needed 😀
I love your English
Your English is so perfect as indian

Your courses are awesome!!!
hi... how to sort the excel data into integer values?
hey, can i do a similar project for my college minor project ?
Is there a reason why the Plots disappear after running the code a second time on Jupyter notebook? They don't show anything anymore.
Please guys help me on the first step got stuck cannot import csv kinda problem with pandas
thank you so much man

Hello,
Did you get this resolved yet? Having the same issue now.
Great video! What coding software did you end up using for this (I haven't seen this python software before which is why I ask)?
That's Jupyter
it gives an error when i run correlation step complaining on data type of team, how can handle ?
I have this too, were you able to fix it?

Great video. Thanks for sharing your knowledge and expertise. I ran into an issue in the "corr()" step.
teams.corr()["medals"]
ValueError: could not convert string to float: 'AFG'. May be I can remove this column before doing the corr() call.
i had the same issue. what did you do to solve it?
teams.drop(["country", "team"], axis=1).corr()["medals"]
this code can work
add this to corr(numeric_only=True)["medals"]

how to correct it or what i had wrong
go to the document u download and take it's link and put it Instead teams.csv
