      This is the magic of RUclips. Shorter videos are often more information-dense and have "less noise" -> Less text = less things that you will mistakenly focus on instead of the true Banger concept.
      Teachers spend 30s explaining what we will learn. Everybody misses this part and are confused for th rest of the course. Here, we have a full 2-5min explanation of what we are talking about, then we delve in the subject.

      @@taheralipatrawala7300 no, i was in a coding boot camp but they kept dropping the ball so i was stuck waiting for long periods of time while they fixed mistakes and put the curriculum on hold so i enrolled in another course and they both ended up finishing around the same time.
      Then i enrolled in something else after, all the while i have a growing project portfolio full of cool projects people like discussing, which is pretty big if you are good at the interview stage.
      Tech is an interesting field in this respect:
      experience and education are both good, but both is great.

    There is so much, even too much, information out there on various topics. And too many people just give a talk, pouring out their expertise without considering how fast they're going, where their audience is coming from.
    I felt that wasn't as much the case here. Great job!

    1:30 To test how each machine learning model performs with our test data, we can use a confusion matrix.
    Let’s say we have two outcomes from our classification model, either true or false, then the rows can be the predicted values for our model (true and false) and the columns can be the actual truth results of our data (true and false)
    Data points can be classified by our model as true positive (both predicted and actual are true) or false positive (predicted is true but actual is false) or false negative (predicted is false but output is true) or true negative (predicted is false and actual is false)
    4:30 using confusion matrix to compare random forest and logistic regression.
    5:15 confusion matrix for multiple class classification, the diagonal represents number of true positives

    Sir, I am from India , I was enrolled in a Data Science programme which costed me 45k the python and SQL courses were nice but then also I had to put a lot of effort mastering it , but the ML classes was not at all good, currently my class is going on ML when I am writing this comment but I am not attending it and rather watching your video , I don't want to waste my time there just to satisfy myself that I have paid a huge amount of money rather I want to utilise my time into the video where I can really understand something.
    Lastly I want to thank you for providing such awesome content , currently I am not working so I have some limitation for spending money, but when I will get a job in data Science and ML I will surely contribute to this channel ."Thank You Again ....."
