It is vital that credit card companies are able to identify fraudulent credit card transactions so that customers are not charged for items that they did not purchase. The dataset used contains transactions made by credit cards in September 2013 by european cardholders. This dataset presents transactions that occurred in two days, where we have 492 frauds out of 284,807 transactions. The dataset is highly unbalanced, the positive class (frauds) account for 0.172% of all transactions. The dataset has been collected and analyzed during a research collaboration of Worldline and the Machine Learning Group (http://mlg.ulb.ac.be) of ULB (Universite Libre de Bruxelles) on big data mining and fraud detection. More details on current and past projects on related topics are available on http://mlg.ulb.ac.be/BruFence and http://mlg.ulb.ac.be/ARTML.
As the dataset was created using a PCA, preprocessing of data is of little scope in this problem. The imbalance between classes is compensated using oversampling and undersampling. The logistic regression, random forest, support vector machine, k-means are used, within a cross-validation framework. Lastly the recall and accuracy are considered as metrics while choosing the best classifier. A buffer section on outlier detection is added at the end.
Deep Learning Project- Learn to apply deep learning paradigm to forecast univariate time series data.
In this supervised learning machine learning project, you will predict the availability of a driver in a specific area by using multi step time series analysis.
In this project, we are going to talk about insurance forecast by using regression techniques.
