      Hello, this may be late but i'll try to answer. Basically the output column is the target column. The example used on the video is binary classification, so there are only two class which is assigned to 0 and 1. If your target is not in numeric value, you can convert it yourself using pandas with assign function if i'm not mistaken.

  • @madunishant6052
    @madunishant6052 5 років тому +1

    Hey Krish! I have few questions based on encoding which are
    1. Let’s suppose I have a feature which has 1000 different categories which I need to convert to either an integer/float how should I do that?Here I can’t go for one hot encoding as it might create 999 columns.And also it has only 1100 record /rows by which even though going by the “one hot encoding with multiple categories” method the most repeated categories will be extremely less how do we handle it in such cases?
    2. In Ordinal encoding why are the ranks need to be assigned to a categorical label instead we can give some random unique number to the categorical values without ranking them for example PhD as 1 , BE as 2, Masters as 4 and Stats as 3.
    3. Also regarding “Label Encoding” how are the ranks decided say if PhD needs to be given higher rank let’s suppose ‘4’ how can a library know that it should be given a higher rank? Or is it something else that in the library code we need to manually set it?

      For the first point u should not apply one hot encoding instead we can go ahead with Mean encoding.
      Label encoding for ordinal categorical will be assigned with ranks. In this case PhD should have a highest rank or label. This will help us to specify the ML algorithm where in we are providing higher importance to phd

  • @HarpreetKaur-qq8rx
    @HarpreetKaur-qq8rx 4 роки тому +8

    Hi Krish, I am confused with your explanation. My doubts are: You said for target guided ordinal categories you are assigning the rank based on mean values then how does it matter if the category is nominal or ordinal since the ranks are assigned based on mean values and not the inherent rank/order of the variable itself. Also for label encoding the number actually mean anything since it isn't like price/sales where the number holds significance so won't the result be junk/unusable and if they are usable then how do you interpret the result

    • @benvelloor
      @benvelloor 4 роки тому +4

      If the categorical feature is ordinal then we can assign labels to it. Here the category which obtains highest target mean will be assigned the highest label value. If the categorical feature is nominal then we cannot assign labels.
      This is because in label encoding the number does mean something. Different numbers teach the model to make different predictions. For example, a value of 4 (PHD) in the salary prediction example results in a prediction of higher salary whereas a value of 1 (Bcom) results in prediction of a lower salary! This happens because, in the training data, entries with PHD as educational attribute will have a higher salary in the target column. This is generally useful when we do not know the exact ranking!! We find the correlation on the categorical feature to the target and then rank categories according to the mean of the values observed in the target!
      If the categorical feature is nominal, we do not want the algorithm to learn more from some categories compared to the others. Hence using one hot encoding, we set the values to be 1 and 0.
      Now as for Mean encoding of nominal categorical features, we essentially map a relationship between the categories and the target. When applied to the example of pin code numbers, some pin codes may result in higher salaries (assuming we are trying to predict salary again). Hence the mean of that pin code will be higher. We simply map in the mean value in place of that category!! So now when the model learns, it will know that a data point with high value in the pin code feature should predict higher salary!
      Regards!

    How would we calculate the mean if the output is a multi class classification. In that case shall we take 0,1,2 as output?
    In the eg you have taken 0&1. Here we can do the calculation. What if there are more than 2 classification outputs.
    If you could attach the notebooks in a link it would be easier i guess instead of sending personal emails. Just a suggestion.

    Hi Krish,
    At 20:23 the Label for A - 0 and A - 1 will be different based on mean right ?
    for example the mean will be calculated this way right ?
    A - 1 => 0.73
    B - 1 => 0.6
    C - 1 => 0.4
    A - 0 => 0.5
    B - 0 => 0.35
    C - 0 => 0.36
    Then the ordering of feature will be as below right ?
    A - 1 >> B - 1 >> A - 0 >> C -1 >> C - 0 >> B - 0

    Dear Sir - In one hot encoding with multiple categories - We are only taking the top 10 categories and applying One Hot Encoding on the same. What about the other categories, as we are dissolving the column completely to apply One-Hot-Encoding.

      use groupby function to create a data frame consisting of mean value of a feature wrt to the id , or name( of which you want to know the value , then use merge function to add this mean value data frame to your original data frame( which you will use for training you model)

    I read on scikit learn documentation that label encoding should be applied only to the output column.

    For one hot encoding with multiple catergories, it will create columns for top most categories.Then what happened for the records with remaining categories. Do they have 0 for all columns.
