    I don't know every time what to say! How can u explain the best & in simplest way possible every time ? How do u make awsome representation , simplest explaination with examples anyone can understand? How do u do that? Thanku so much for working hard. U really r very professional , knowledgeable , ur teaching skills r also the best. I m great fan of this channel. Hatts off....God bless u ! U r the best one so is The Campus X.

      Couldn't agree more. Hands down Nitesh sir is best when it comes to explaining hard core topics. I was blown away when I saw the "Principal Component Analysis" lecture. Sir is true gem 💎 for us.

    Your videos are really helpful. I am facing this issue of unable to think of the next step while coding. If someone tells me what to do or i see the solution, it takes ne seconds to write the correct code. Any idea how I can overcome this barrier. Thanks again for the awesome uploads.

    Is is ok to remove a column from a df which has high correlation with some other independent column in a classification problem? Or it should be done only in case of regression?

    Hi sir, that was very helpful indeed. However, one question still remains..like, how it is impacting the algorithms??

    • @ajaykushwaha4233
      @ajaykushwaha4233 2 года назад

      It all depends on computation power and time. If more features are there with multicolinearity that mean many features are giving same information and it is better to skip those features. So less features mean computation time will be less which is good.

    do we check Multicollinearity for classification problem as well ?

    • @pulkitaneja1739
      @pulkitaneja1739 2 года назад

      If your classification model is linear, ex: logistic regression, then you can check for multicolinearity

      Do more interesting projects which aligns with the vacancy that you're applying for and add it in your resume. Don't refrain from applying even if the requirement says 2-3yrs of experience. Once they go through your resume there's a High chance that you'll be called up for an Interview and then on it's your show

    But sir why exactly multicolinearity affects the performance of regression algorithms(if only prediction matters to us).
    I don't see any effect on the accuracy, although yes, it would take more processing power which could've been optimised but nothing else...

    • @geethasubramanyam
      @geethasubramanyam 5 месяцев назад

      From what I understand, multicollinearity doesn't impact the predictive performance of regression models significantly. I believe that it makes it difficult to individually identify the contribution of each predictor variable to the response variable. So the impact is on interpretation than on prediction, to put it simply.
