Hey, have build the same project as u teached but with different dataset & while using logistic regression im facing the ValueError: as 'Could not ocnvert string to float' what should i do?

[@shaikhirfan7749]

What if i use Random forest (isolation forest algorithem)Instead of logistic regression?? With svm also bcz of the data is imbalenced and having some outliers?

[@subhamsaha2235]

Very nice explanation and really liked the video. The classification report is also very good measure of the model. I think if we do cross validation and use some boosting techniques then the score can be increased more and one more imp thing is that here accuracy score doesnt matters, main is precision and recall because we cant let a fraud trans to become non fraud. Thank you

[@Siddhardhan]

nice insights. you can definitely try to do some optimizations.

sir I have a question whenever I run this part of the code: credit_card_data['Class'].value_counts() it doesn't show the exact amount of fradulent transaction for example its supposed to show 492 but in my case its showing 239 why is that sir?

[@yassine.h3262]

Great. I would like to add some remarks that might help in future projects : - The way you dealed with imbalanced data will certainly lead to bad predictions, because alot of information were lost when taking a small sample from a large dataset. - use SMOTE instead of sampling - use decision trees or random forests algos they are better when dealing with imbalanced data - use more evaluation metrics like ROC curve, F1 score, recall...

How is he balancing the data ?

Since the data is balanced, accuracy score is a good metric. If the data is not balanced then something like Sensitivity, specificity can work

Hi, great work. I have a question. What is role of time feature in dataset towards prediction of fraud? Does fraudulent translation depend on time feature or we can just drop it? Hope you can answer.

hi! we cannot drop time feature. if you analyse the data more, you will get to know that the fradulent transactions are more at some time period.

For imbalanced dataset is accuracy a good metric to measure the robustness of a system?

as we have down-sampled the data, we can use accuracy. if we don't rectify the imbalance issue, we can use precision & recall as metrics for evaluation.
