Do you have to trace back the original definitions for each mean and what happens if there are repetitions?

Hi Krish, I have a question. So, we are normalizing all numerical fields which will make it in the range 0 to 1. While encoding categorical variables, we "one hot encode" a few which will make them either 0 or 1. However, there are a few categorical fields where we are "label encoding" as order matters. It would be encoded like 1,2,3,4,.... which is not in the 0 to 1 range unlike the first and second case that I had discussed. I would like your advice here whether I need to normalize after label encoding the data and range of this case alone won't be in 0 to 1 and normalizing would make it in 0 to 1 range.

I agree with all the encoding you treated, however I got doubts on assigning an ordinal label based on the mean value of the output. By doing this you are setting the distance between levels to one, while in reality, based on the output mean, some level might be close than others, with distances less than or more than 1. What do you think? I would also point out the risk of data leak in case of mean encoding, for this reason I'd add a random noise to the mean

@antrikshsingh7798 4 жыл бұрын

Hey awesome video there. Just one doubt in the KDD orange competition. They came up with top 10 categories. How exactly did they arrive at the figure 10? Isn't covering certain variance of total categories would have made more sense? What I mean is, let's say if there are 40 categories in a column and if I select 12 categories that covers a total of 80 percent or 90 percentage of all rows. Wouldn't that make more sense rather than choosing static figure of 10.

Hi krish, I am your new subscriber. I just started learning ML 2 months ago. I learned a lot from your videos. I just have a question regarding mean encoding. I have computed the mean encodings using the training set to avoid leakage but I have issues with the encodings identified in the training set when mapped to the test set because there are cases where some categories in test set are not identified and encoded in the training set. Can you tell me how I could resolve this?

@SumitSharma-pu6yi Жыл бұрын

May be a late reply.. then give those mean encoding of 0 because they didnt occur in the training set. There is also a stratified sampling approach.

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

Hi Krish, We cannot perform Mean or Target encoding on test data because we don't have target column in test data. So how can we deal with such a situation where we have variable with multiple level in it? I am talking in respect with Hackathon where we generally don't have target variable, this is something which we have to predict. Would appreciate your help.

@kentakeshi8716 6 ай бұрын

You already got the ordinal number or the float number for each category class from the training data . So you dont need to do it again in test data. You will simply use it. You might already know this. But I am answering if someone else has this doubt.
