- Logistic regression is a process of modeling the probability of a discrete outcome given an input variable. The most common logistic regression models a binary outcome; something that can take two values such as true/false, yes/no, and so on.

Mujhe samajh nhi aara ki koi project mil gaya aur use first kya karna hai kaise kaise karna hai
Elasticnet Skeweness quadratic anova test sub kahan use karna hai aur kaise use karna hai
I'm very confused
Thanks sir 😍
This is incomplete video like others, what about 3rd category " Setosa", which you removed before developing your model. Also you didn't show predicted value or category with new inputs?
It would be if you can explain the things for beginners. Basically this is a feedback for you it would be better if you explain more in your every video instead of explaining the upper things only.
It is beginner level only .. i m also a beginner … U just need to learn about pandas and some libraries prior to..
Sir, what about activation functions? You have not talked about activation functions in your model implementation.
Accuracy formula reverse nahi hoga kya??
accuracy_score(y_true, y_pred)
can u please explain logistic regression with its dot product and mathematical implementation on python?
Sir keep going with Stats playlist (in Hindi)
Rocking ...Sir glad to hear you in Hindi. I hope ML ka jo dar lag raha hai woh nikal jayega aab. Thank you so much Sir
Full course data science sikhne ke baad job mil jayegi sir?
I have 15 year of experience in html, excel , ms word
Sir please reply.
Sir abhi python Sikh rha hu
Hello sir
I'm afreen from hyderabad
Can you make 1 complete video on any
Dataset and explain how can we do complete data science project step by step
Eda feature engineering feature scaling and train and test data algorithm Pridction
How to test this model using new data set. Can anyone help me ?
How did you use y_pred u didn’t define it
Hi Krish Naik Sir, Request you to upload some ML Use case on Healthcare.
18:14 huyii nahi Sir hue 😂
Great Explanation!
aapne x me se target variable nikal diya pahele hi. to ye train kaise karega?
There is y train also
bro error here which didnt findout the solution
---------------------------------------------------------------------------
KeyError Traceback (most recent call last)
in
1 #find out the category of setosa species
----> 2 data=data[data['species']!='setosa']
3 data.head()
2 frames
/usr/local/lib/python3.8/dist-packages/pandas/core/indexes/range.py in get_loc(self, key, method, tolerance)
386 except ValueError as err:
387 raise KeyError(key) from err
--> 388 raise KeyError(key)
389 return super().get_loc(key, method=method, tolerance=tolerance)
390
KeyError: 'species'
Thank you sir.
When I'm trying to run classifier_regressor.fit(x_train,y_train) it says input contains Nan,infinity value loop or too large value for dtype float. I'm running code on colab. How to solve this error?
Please check for your Nan values or missing values before training model.
@@jitendrarathod6246 I did that but still got the same error
best video on end to end logistic regression, thanks
Sir, How to choose the value for random state? is it always supposed to be 42?
you can choose any random value.
Sir when I'm removing setosa I'm getting "NAN" Why?
Please let me know if you get the solution to the same, also are you using Colab by any chance
did you get the soln?
BCZ IT HAD NONE VALUE
what is difference between best score and accuracy? I tried doing with different datasets and I am getting same value for best score and accuracy
Finally got TH-cam channel where I can learn every thing ❤
💥thanks sir your 7days videos are really helpful
Hello sir, How to solve A Classification problem in which training data has only one class? 'This solver needs samples of at least 2 classes in the data, but the data contains only one class: 1', please help me out
Sir in cell number 11 I am writing the same code using .map() method but I am getting NaN values in species column as an output.pleas help.
i think you should check the place where species many of the data set there was written like = class =
Sir please upload more lectures of ML
Data science ka course bhi hindi me ayega kya?
Hello sir
Can I apply for data science jobs after doing MCA aiml specialization course
Please clearify my doubt.
The best and detailed tutorial. Thank You So much sir.
can we apply logistic regression for positive, negative, and neutral output of 3 dimensional data example. positive=1,negative=0 and neutral=2
Yeah but in this case u apply softmax regression becoz u have 3 clasess like u say positive negitive and netural
Thank you sir
Thank you Krish naik Sir
Very well explained
hindi me best lag raha hai sir
thanks sir for this amazing video
konsa shortcut use kr rahe ho defulat value dekhne ke liye logistc reg me
Shift+tab
Thanks
How do we select relevant features?
Principal component analysis
Well explained!
sir please explain this implementations in English language only !!!!
Thnnnquu so much sir for this video 👍👍👍
