I think that they are fantastic. I attended Yale and Stanford and have worked at Honeywell,Oracle, and Arthur Andersen(Accenture) in the US. I have taken Big Data and Hadoop,NoSQL, Spark, Hadoop... Read More
The project orientation is very much unique and it helps to understand the real time scenarios most of the industries are dealing with. And there is no limit, one can go through as many projects... Read More
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.
In this data science project, we will look at few examples where we can apply various time series forecasting techniques.
