Post which various regression techniques like Logistic/Tree/Random Forrest were applied to figure out the main driving factors, also to find the best model providing the accuracy.

Result: Initial accuracy found for predicting a card transaction as threat or not, is around 88% but the model validation on various kinds of data is still in Progress.

Tools and modelling technique used: Python and various regression techniques like Logistics/Tree/Random Forest, Cross Validations
