for age factor should scaling be consirdered ? if i dont include age in scaling will it affect in accuracy of the model?
I think it should be considered, you can try and see what effect does it have. Maybe it can increase the accuracy of the model.
okay i will thank you very much
Hey @aakashns ,can we have a friendly kaggle competition(like we had for pytorch: zero to Gans) for this course as well?
model.fit(train_inputs[numeric_cols + encoded_cols], train_targets)
i have tried running this block of code and i keep getting this error
ValueError Traceback (most recent call last)
----> 1 model.fit(train_inputs[numeric_cols + encoded_cols], train_targets)
ValueError: operands could not be broadcast together with shapes (16,) (102,)
@aakashns Sir , I built the model on breast cancer logistic regression , the model accuracy came out to be 91% , but when I was testing this model’s efficiency on random_guess model and all_no model , the accuracy came out to be 54% and 36% respectively.Is it expected or something is wrong?
Also , I was testing the model by providing the new single input in the end for prediction and I was scaling it the way I did for training and test set , but the new single input was not getting scaled.I am using the same scaler object.I wonder why.
I don’t remember exactly, so could be wrong but I think the
random_guess model and
all_no model were models that predicted a
random guess and
no respectively for any input value.
They are basically for reference, like suppose the model we trained has an accuracy of 50%, and then you see that a
random_guess model(a model that predicts with a
random guess and requires no training/modeling, etc.) has an accuracy of 54%
Then this would imply that our 50% accurate model is not a very successful model and requires changes.
In case I remember wrong and
all_no are test cases, then you would have to check your model for overfitting.
