Sir, Internet is flooded with Data Science materials,but none of it can match your standard. You keep things simple. Your can make any one fall in love with data.
Dr, thank you for the great video. I have a quick question. Do you think it is available to use the method of video while predicting the response variable is not value, but percent change from baseline? (e.g, -10%, 20%, -15%, etc.)
If you run str(forecast), it will show you what's inside. And yhat is one of the column that contains predictions. Similarly, 'm' contains lot of info too and we are selecting something that we need.
Hello Sir, I am not able to use prophet function & make_future_dataframe from prophet package(while using prophet function, I am getting this: Error in prophet(df) : could not find function "prophet"
Thank you Sir. I am learning too much things. 🙏🙏🙏 Sir, please make a tutorial for forecasting the number of cases using polynomial equation instead of linear, I think it would be more accurate in this scenario. am i correct, sir?
Thanks for the suggestion! However, note that the accuracy also depends on data and sources that generate data. This is a very powerful method and you can also improve accuracy by making some small adjustments to the model.
sir whenever I try to run this step "plot(actual, pred) I am getting an error Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ what to do sir
Dr. when i plot the predicted data the Y is in format 0e+00 1e+06 although i checked the structure it's numeric as i converted it as you said so what might be the problem?
If you look into tsc before extracting just US related info, you will see that it contains data from across the world. If we only want a specific country, we can do it by specifying Country.Region = "US".
@@bkrai thanks for replying sir...My question was a bit different... Since the column names are Country_Region....Then how are we getting output on using Country.Region( '.' Instead of '_') ...

Interesting Dr. Bharatendra Rai... Sir I appreciated your lectures..It's very simple and informative. Thanks again.
You are most welcome!
We were already missing your wonderful videos. Cheers from Brazil.
Thanks for comments!
Greetings from China. Thank you Dr.Rai!!
You're most welcome!
This is great Dr. I am apply the codes on data for East Africa. Thank you so much
Welcome!
Nice session 💐💐💐💐👌👌
Thanks!
Your videos are really great. Don't stop it anytime ,keep posting more videos♥️
Thank you so much!!

That should work fine.

Thank you sir for using Prophet.

Which is the better model arima or prophet ? How we decide which model to pick?
I've used R-sq, but other metrics such as rmse is also popular.
Thank you sir and you are the best 👍
Thanks for comments!
Dr. Bharatendra Rai please help me with this : Error in library(covid19.analytics) :

You need to first install that package and then run the library line.

Hello Sir,
I am not able to use prophet function & make_future_dataframe from prophet package(while using prophet function, I am getting this: Error in prophet(df) : could not find function "prophet"
Make sure to run library(prophet)
I did sir, but could not find both the functions. Is any other package required to install before the prophet?
If package is installed properly, then probably look for any typo in the codes.
Thank you Sir. I am learning too much things. 🙏🙏🙏

Can you make a video on machine learning for covid 19 prediction (polynomial regression)

Hello sir, How can I make forecast accuracy for this prophet model?
You can use R-sq used in this video.
Thank You Sir for this great video. :)
Most welcome!
Thank you very much sir .. we are learning a lot by following your videos.. it would be great if you can share the code too for learners to practice 🙏
The link should now be available in the description area.

Sir which deep learning algorithm is used in this project?
It was not deep learning, but forecasting here.
when I put str(tsc) my Confirmed column shows as factor but in your it shows character. Do you have any thoughts why its is different
than yours?
As long as you can covert them to numeric, it should be ok.
sir whenever I try to run this step
"plot(actual, pred)
I am getting an error
Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ

Dr. when i plot the predicted data the Y is in format 0e+00 1e+06 although i checked the structure it's numeric as i converted it as you said so what might be the problem?
1e+06 is 1000000, it just more compact notation.

Why do we use Country.Region = "US" to get US specific data...when the column names is Country_Region
If you look into tsc before extracting just US related info, you will see that it contains data from across the world. If we only want a specific country, we can do it by specifying Country.Region = "US".
@@bkrai thanks for replying sir...My question was a bit different...
Since the column names are Country_Region....Then how are we getting output on using Country.Region( '.' Instead of '_') ...
If you look at View(tsc), column name is Country.Region
excuse me sir when I run this codes this error appear Error in setup_dataframe(m, history, initialize_scales = TRUE) :

Sir I had question on GAN.
Suppose I have 25 images with me , how many new images can I generate from them using GAN.
Note that 25 is a very small sample, but once GAN can be trained, there is no limit on how many you can generate.
@@bkrai But the generated data would be redundant. I guess.
The new images are all likely to be slightly different from each other.
@@bkrai I will try it and get back to you , Thank you so much Sir.
